The Habsburg Monarchy

The bloody sabre

Süleyman the Magnificent inherited his father's own unfinished design on Hungary and pursued it with a skill and ambition the Ottoman throne had never before combined. He took Belgrade - the fortress that had once defied Mehmed II under Hunyadi himself - through simple treachery rather than the desperate defense Hungary's own defenders had mustered two generations earlier, added Rhodes to his conquests soon after, and by the winter of 1525 was massing his forces on Hungary's own frontier. He found the kingdom badly placed to resist him: a young king absorbed in pleasure, a nobility fractured by faction, and Christian Europe too consumed by its own religious quarrels and wars to send help.

"To arms!"

When Süleyman finally crossed the Danube with two hundred thousand men, Hungary's own king revived an old custom - a blood-stained sabre carried from village to village as a call to arms - but even that could not unite a nobility split into rival factions. Louis's own council urged patience: hold a defensive position until Bohemian, Austrian and Transylvanian reinforcements arrived. A bishop commanding the vanguard, flushed with a few minor skirmish victories and convinced God had already promised him the field, overruled that caution, and the nobles drowned their own young king's hesitation with shouts of "To arms!" - branding anyone who counseled otherwise a traitor. Louis yielded. On 29 August 1526, thirty thousand Hungarians met Süleyman's army at Mohács, fighting with real religious fervor that could not make up for the disparity in numbers or match the sultan's own tactical skill: twenty-two thousand of the thirty thousand who fought fell on the field, seven bishops and hundreds of nobles among them.

A king drowned in a marsh

Louis himself tried to escape the collapse, but at a marshy crossing near the village of Csele his own heavily armored horse, struggling to climb the far bank, fell backward and crushed him beneath it. A Silesian nobleman who had crossed safely turned back to help, pulled him from the mud and unlaced his helmet, but the king had already been mortally injured and died within moments. Ottoman troops were too close for any proper search, and his body was not recovered for two months, eventually buried at Székesfehérvár. Buda and Pest surrendered without a fight in the immediate aftermath, and only Süleyman's own need to turn back and suppress a rebellion in distant Karaman - sparked by a false rumor of his own death - spared Hungary from being subjugated outright in that same campaign. Louis died childless, the last of his line, and left both the Bohemian and Hungarian crowns open to whichever claimant could actually make good on them.

Two kings in one year

Ferdinand of Austria had two separate grounds to claim Louis's own vacant crowns - old family compacts entailing the succession on the House of Austria in default of a male heir, and his own marriage to Anne, the dead king's sister - but he understood, as his predecessors often had not, that Bohemians and Hungarians valued their right of election too highly to simply accept a hereditary claim asserted over their heads. He offered himself as a candidate through the normal electoral process in both kingdoms rather than resting on inheritance alone. Bohemia gave him little real contest: opposed only by the Duke of Bavaria, he was chosen by a twenty-member electoral committee on 26 October 1526, promised in writing to respect Bohemia's own rights, privileges and customs, and was crowned at Prague with his wife Anne the following February.

A rival crowned the same year

Hungary proved far harder to settle. John Zápolya, Voivode of Transylvania, had led forty thousand men toward Mohács too late to join the battle, and used that intact army to put himself forward as a native alternative to a foreign candidate - convening the estates at Tokaj, where a faction of nobles averse to Habsburg rule crowned him with Hungary's own sacred Crown of St. Stephen that November. Ferdinand's own sister Mary, Louis's widow, countered by summoning a rival diet at Bratislava, where nobles who judged Zápolya's own assembly improperly convened declared his election invalid and raised Ferdinand to the throne instead. Ferdinand backed the claim with real force, marching into Hungary with a combined German and Bohemian army; town after town surrendered without resistance, Zápolya abandoned Buda without a fight, and a fresh diet confirmed Ferdinand's own kingship, giving Zápolya's remaining supporters a three-and-a-half-week ultimatum to submit or be declared enemies of the country. Zápolya's own forces lost engagement after engagement, and he was eventually driven into exile in Poland, sheltered by a brother-in-law king.

A sultan's threat

Ferdinand, secure for the moment in both kingdoms, overreached almost immediately: confident in the strength of his own legal claim, he sent an embassy to Constantinople demanding the return of Belgrade and other fortresses the Ottomans had already taken from Hungary - a demand delivered, by contemporary account, with enough arrogance to provoke Süleyman himself into a furious reply. "Belgrade! Go tell your master that I am collecting troops and preparing for my expedition. I will suspend at my neck the keys of my Hungarian fortresses, and will bring them to that plain of Mohács where Louis, by the aid of Providence, found a defeat and a grave. Let Ferdinand meet and conquer me, and take them after severing my head from my body! But, if I find him not there, I will seek him at Buda, or follow him to Vienna." Zápolya, still fighting for his own restoration, allied openly with the sultan against Ferdinand, and within three years Süleyman himself was marching on Vienna at the head of an army numbering, by report, three hundred thousand men - a threat the newly composite Habsburg state would have to answer at the very gates of its own capital before its first decade was out.

The flotilla that never arrived

Süleyman crossed into Hungary in the spring of 1529 with an army put at three hundred thousand men, and found almost nothing standing in his way. John Zápolya, driven into Poland after Ferdinand's own troops had broken his cause in the field, met the sultan's camp on the plain of Mohács and was received with regal honours - a client king restored by the same power that had killed his rival's predecessor on that same ground three years before. Süleyman advanced through Pest, took Buda by the treachery of its own garrison and handed the castle to Zápolya, then pushed on almost unopposed - Wissegrad, Gran, Komorn, Raab and Altenburg fell in quick succession - until his army stood beneath the walls of Vienna itself. Coxe's own explanation for how little resistance so warlike a kingdom offered is unsparing: Bohemia was too divided by its own internal feuds to send help, Charles was occupied with his Italian wars, and the German states were too consumed by religious antipathy toward one another to unite against a distant enemy. Ferdinand did what he could regardless, throwing some twenty thousand reinforcements into the city and pressing the German diet for troops; a relief corps under Frederick, Count Palatine, reached Krems in September, too late to enter Vienna itself but near enough to keep the Turkish camp in continual alarm.

A dilapidated wall and a sunken flotilla

The city Süleyman found was badly placed to withstand him: open, extensive suburbs and walls built in an old style never meant to answer artillery. What actually held it was a combination the sultan had not fully weighed - the skill of the commandant, Nicholas, Count of Salm, the courage of his garrison, and the loyalty of Vienna's own burghers, reinforced by a stroke of luck rather than design. The flotilla carrying Süleyman's heavy artillery up the Danube never reached the siege at all; the garrison at Pressburg dispersed or sank it on its passage upriver, leaving the sultan to invest a European capital without the guns that would ordinarily have opened its walls. Reduced to mining, he spent thirty days attempting to breach the defences from beneath rather than above, and every assault that followed a breach was thrown back by Salm's own garrison. A last, desperate effort in the closing days of the siege fared no better than those before it, and with winter closing in and the fear of Frederick's approaching relief force weighing on his own council, Süleyman broke off the siege and turned back toward Buda.

A crown delivered on the retreat

He did not leave empty-handed. At Buda, before a large assembly of Turkish and Hungarian nobles, Süleyman proclaimed John Zápolya king in earnest, received his homage, and handed over the sacred crown of St. Stephen and the rest of the regalia he had held since capturing the city. Zápolya kept a Turkish garrison in Buda as the price of his own restoration, and Süleyman withdrew from Hungary the way he had come - devastating the country as he went, carrying off captives in numbers large enough, Coxe notes, to draw tears even from the king who owed his own throne to the army doing the devastating. Ferdinand, watching the Turkish army retreat, judged the moment right to move against his rival directly, retaking Altenburg, Gran and other posts before the season closed against him - the opening exchange in a contest over Hungary that Süleyman had left unsettled on purpose, and would return to finish himself within three years.

A siege too petty to mention

expansionDrafted from Coxe, History of the House of Austria, from the Foundation of the Monarchy by Rhodolph of Hapsburgh to the Death of Leopold the Second, 1218-1792 (1847)

Stung by his failure before Vienna, Süleyman spent two years preparing a second invasion meant to settle Christendom's fate outright rather than merely punish Ferdinand's rival claim - not just the Austrian dominions this time, but Germany itself. He marched with a larger army than he had ever led into Hungary before, and after a march of fifty-six days reached the country around Belgrade, spreading what Coxe calls a "direful alarm" through provinces that still carried the fresh memory of the last invasion's devastated fields and captured families. Ferdinand tried negotiation first, sending ambassadors to Süleyman with rich presents and proposals of peace; the sultan answered by ordering the ambassadors to follow his camp and await his pleasure, then embarked his artillery in a flotilla of three thousand vessels and led his army through the western provinces as though making for Styria over the mountains.

Eight hundred men at Güns

His route brought him to a small, badly fortified town called Güns, garrisoned by only eight hundred men under Nicholas Jurišić - and there his advance stopped for nearly a month. The Turkish army planted artillery on the surrounding hills and even on earthworks raised above the town's own rooftops, breached the walls repeatedly, and assaulted the breaches again and again; Jurišić refused every bribe, promise and threat alike, and after twenty-eight days Süleyman accepted a token submission rather than press a siege that a garrison of eight hundred had already cost him a month to fail to finish.

Christendom together for once

The delay before Güns gave Ferdinand and Charles exactly the time they needed. Charles had just pacified Germany's own religious disputes with the peace concluded at Ratisbon on 23 July 1532, and turned that settlement immediately to military account, drawing Catholic and Protestant princes alike into a common muster with a unanimity Coxe calls almost unexampled. Charles brought veterans from the Low Countries and Italy, Ferdinand raised troops from Bohemia and the neighbouring provinces, the pope sent subsidies and officers, and even King Sigismund of Poland let his own subjects join the field. The combined force that gathered under Vienna's walls ran past ninety thousand foot and thirty thousand horse - the flower of Germany, in Coxe's phrase, from the Vistula to the Rhine.

Süleyman, discouraged by how long so small a place as Güns had held him and alarmed by the size and unanimity of the army now waiting for him at Vienna, gave up his design on the capital outright. Separated from his own artillery flotilla, which dared not run the guns of Pressburg a second time, he turned his irregular cavalry loose to raid the countryside and crossed the mountains to Graz instead, avoiding the very engagement his own massive preparations had seemed built for. Charles, judging correctly that winter would finish what he chose not to risk in battle, kept his army at Vienna and let the season do the work; a diversion by Andrew Doria's fleet against Ottoman positions in the Aegean, including the capture of Coron, added pressure from the opposite end of Süleyman's own empire.

An army too useful to keep together

Süleyman withdrew in September 1532 by the same route he had advanced on, and his retreating irregulars, cut off from the main army's protection, were cut to pieces or captured almost to the last man. The retreat opened a genuine opportunity to recover Hungary outright, but the army capable of doing it evaporated almost as quickly as it had assembled: winter approached, provisions ran short, disease spread through the camp, and Charles himself cared more about convening a general council to settle Germany's religious quarrel than about finishing a Hungarian campaign. The great combined host dispersed, and Ferdinand was left, within a season, with barely more than his own forces - to face a rival king still very much in the field, and a sultan who had lost a battle of nerve rather than a war.

A monk who put on armour

Years of indecisive raiding followed Süleyman's retreat from Güns, broken by occasional truces and treaties that changed little while John Zápolya kept possession of most of the kingdom. Both rivals came to see, eventually, that the sultan profited from their quarrel far more than either of them did, and in 1538 they concluded the treaty of Várad under Charles V's own mediation: Zápolya would keep the royal title, Transylvania, and whatever Hungarian territory he already held for life, but on his death his own male heirs would inherit only his family's private lands and the voivodeship of Transylvania, while the crown itself reverted to Ferdinand. The arrangement favoured Ferdinand precisely because Zápolya was old and unmarried - until, almost as soon as the ink dried, he married his young cousin Isabella of Poland. She bore him a son, John Sigismund, and a fortnight later, on 21 July 1540, Zápolya died of a stroke.

The bishop who would not yield an inheritance

Ferdinand's claim under the Várad treaty was now, on paper, simply due

• but Isabella refused to surrender a kingdom she had just become regent of, backed by a churchman whose ambition matched her own resolve. George Martinuzzi, bishop of Várad, had risen from a poor Croatian family through a monastery, a friendship with Zápolya formed in his own youth, and a talent for both administration and command that let him move, in Coxe's description, as easily in armour as in vestments. Under his direction a party of Hungarian nobles crowned the infant John Sigismund in place of a proper election, carried mother and child to Buda, and sent to Constantinople for Süleyman's own protection - a maneuver Coxe judges a breach of both patriotism and good faith, and the opening of a civil conflict that would keep Hungary divided under Ottoman influence for more than a century.

Ferdinand answered first with diplomacy, offering to hold Hungary himself as an Ottoman fief on the same terms Zápolya had once accepted. Süleyman refused outright - an infant he could crown or depose at will suited his own purposes better than a grown king from a powerful family who might one day outgrow his tribute - and demanded, as the price of peace, that Ferdinand give up not only Hungary but acknowledge Austria itself as an Ottoman fief. Ferdinand sent an army instead, which reached Buda in 1541 and besieged Isabella and her infant son in the citadel; Martinuzzi held the defence with what Coxe calls singular skill and resolve until the pasha of Belgrade arrived and broke the siege outright.

Ten thousand janissaries in the citadel

Süleyman followed in person with a still larger force, took the gates of Buda by stratagem, and secured the queen and the infant prince under a garrison of ten thousand janissaries - occupying the very capital he had handed Zápolya as an ally a decade before, this time for himself. Buda's fall gave the sultan command of the Danube and a base from which to extend his own territory on both banks, and every attempt Ferdinand made to recover the lost ground failed: his brother Charles was absorbed in his own ambitions elsewhere, imperial subsidies arrived scant and irregular, and his own hereditary lands were exhausted by more than a decade of intermittent war. By August 1545 he had no real choice left but to ask Süleyman for a truce, granted for five years only at the French king's own intercession, and only on humiliating terms: an annual tribute of thirty thousand ducats, and formal status as a feudatory of the Ottoman Porte.

Isabella and Martinuzzi were made, in the same settlement, to renounce the crown outright in the infant's name; in exchange John Sigismund kept Transylvania and the district east of the Tisza as a tributary principality Süleyman could resume at pleasure - not the kingdom his father had died holding, but a fragment of it, held now on Ottoman sufferance rather than Hungarian election, and the durable shape Hungary's own three-way division between Habsburg, Ottoman and Transylvanian rule would keep for the rest of the century.

An ear cut off and sent to Ferdinand

expansionDrafted from Coxe, History of the House of Austria, from the Foundation of the Monarchy by Rhodolph of Hapsburgh to the Death of Leopold the Second, 1218-1792 (1847)

The 1545 truce bought time rather than peace. Within Martinuzzi's own regency government, rivalry between the bishop and his fellow guardian Petrovics, compounded by Ottoman exactions the country could no longer absorb, pushed Martinuzzi himself toward the enemy he had spent a decade resisting on Isabella's behalf. In 1550, backed by his own partisans and an Austrian corps under General Castaldo, he pressed Isabella - partly by persuasion and partly by force - into ceding Transylvania and John Sigismund's Hungarian possessions to Ferdinand outright, taking the Silesian duchies of Oppeln and Ratibor and a cash payment of 100,000 ducats in exchange, and surrendering the crown and regalia the Zápolya family had kept since Süleyman handed them over at Buda. Ferdinand rewarded Martinuzzi with a cardinal's hat, the archbishopric of Gran, and the governorship of Transylvania itself.

A colleague turned accuser

The reward carried its own poison. Ferdinand split military authority between Martinuzzi and Castaldo, a Spanish general whose own haughty temper matched neither the cardinal's influence nor his methods, and the two men's rivalry curdled quickly: Martinuzzi used his own standing to obstruct Castaldo's command, while Castaldo fed Ferdinand a steady account of a minister he suspected - or claimed to suspect - of secretly angling to hand Transylvania back to the Turks. Ferdinand, already wary of a subject whose ability he could not match with trust, concluded there was no safer remedy than to have him killed. Castaldo had the cardinal's own secretary carry out the killing, visiting Martinuzzi's residence at Vinţu under the cover of ordinary business on 19 December 1551; when the first knife-blow to the neck failed to kill him, Martinuzzi fought back and wrestled his attacker to the ground before the rest of the party burst in, cut him down with a sword, and mutilated the body further - and, in a detail Coxe records without comment, cut off an ear notable for a distinctive tuft of hair and sent it to Ferdinand as confirmation the deed was done.

The province the murder was supposed to secure

The killing achieved the opposite of its purpose. No manifesto Ferdinand issued to justify it could reconcile Transylvania's nobles to the loss of the one governor capable of holding the province together, and only the presence of the Austrian army kept outright rebellion from breaking out immediately. Isabella and her son returned within years, backed by a Turkish army under the pasha of Belgrade, and by 1556 the Zápolya family was restored to power in Transylvania under Ottoman protection - Ferdinand keeping only the fortress of Erlau and a strip of territory east of the Tisza for his own trouble. Isabella herself, no happier under Ottoman tutelage than she had been under Ferdinand's pressure, opened talks to cede the province a second time, but died in 1559 before any agreement was reached; her son John Sigismund chose Ottoman protection over a Habsburg settlement instead, demanding the royal title, the disputed district between the Tisza and Transylvania, and the Silesian duchies his mother had once accepted in exchange for all of it.

An old man's truce

Three more years of raiding followed before Ferdinand, wanting a settled peace above all to secure his own eldest son Maximilian's succession, obtained a fresh eight-year truce from Süleyman in 1562 - resuming the annual tribute, promising not to disturb John Sigismund's own hold on Transylvania, and keeping only the ground his own troops already occupied. John Sigismund refused to be bound by an agreement he had no part in making, and kept raiding Habsburg Hungary regardless; Ferdinand, unwilling to risk reopening the wider war over what remained a marginal frontier dispute, absorbed the losses and left the frontier's real settlement to the son whose own accession the truce had been built to protect.

The bloody diet

expansionDrafted from Coxe, History of the House of Austria, from the Foundation of the Monarchy by Rhodolph of Hapsburgh to the Death of Leopold the Second, 1218-1792 (1847)

Bohemia's own crown came to Ferdinand as an elective one, hedged by a constitution that left him, in Coxe's own phrase, "reduced to a mere cipher" in public affairs: no tax, troop levy, war, peace, coinage or law without the consent of a diet of barons, knights and town deputies that he could not even summon without their own cooperation. When Charles moved in 1546 to crush the Protestant League of Schmalkalden and its leader, Ferdinand's own brother-in-arms the Elector of Saxony, Ferdinand needed Bohemian troops for the campaign - but Bohemia's own Calixtin majority sympathized openly with Saxony's Lutheran cause, and an old hereditary compact bound the kingdom to the elector's own family besides. Ferdinand maneuvered around both obstacles: he talked a diet into voting troops for vaguely worded "defence," then marched them against Saxony directly.

A confederacy against the king's own mandate

The troops mutinied the moment their real orders became clear, and when Ferdinand followed with an outright mandate in January 1547 demanding fresh levies on his own authority alone, Prague's own citizens and a mass of nobles and knights answered by forming a confederacy to defend the constitution rather than obey him - collecting taxes, raising their own army, and renewing Bohemia's old compact with Saxony over the king's express objection. Ferdinand's own exchanges with their deputies, as Coxe records them, ran to open threats: "We are determined to prosecute this warfare, whether you will go with us or not... If you persist in your disobedience, you are alone accountable for all the misfortunes which may overwhelm you." The confederates held their ground regardless, mustering troops and warning Ferdinand's own ally the emperor against "the effusion of Christian blood" - until news reached Prague that Charles had crushed the Elector of Saxony outright at Mühlberg.

Six hundred men behind a locked gate

The defeat of their own patron broke the confederacy's resolve overnight; the same assembly that had defied Ferdinand weeks earlier now begged to disband its army and congratulated him on his victory. Ferdinand answered submission with punishment rather than mercy. He marched into Prague at the head of an army, summoned more than six hundred of the city's magistrates, councillors and leading citizens to the palace, had the gates locked behind them the moment they had entered, and from a throne flanked by his own son and the magnates of Moravia and Silesia, read out the charges against them himself. The assembled citizens fell to their knees and begged for royal mercy; he kept them under guard for hours before granting a pardon conditioned on surrendering the city's own arms, tolls, privileges and property outright, and forcing an immediate ratification before anyone had the chance to consult the wider citizenry a confederacy of this size would otherwise have organized behind.

The order that formed the resistance

Similar summonses went to every town in the kingdom except the three that had stayed loyal throughout. Forty of the most prominent prisoners were held back for public punishment: four were executed to open the diet Coxe calls, from that act alone, the Bloody Diet, including a seventy-year-old high judge of the kingdom; eight more in each of the three Prague towns were publicly whipped under a proclamation naming their crime as inciting the people "against their hereditary master" - a title, Coxe notes pointedly, Ferdinand had not previously claimed to hold. A contemporary Bohemian historian's own verdict on the result, which Coxe quotes directly, reads as an epitaph for the towns' political power: "the order of the burghers... disarmed, weakened, chastised, and so much reduced that they can scarcely now be said to form one of the three estates of the kingdom."

An elective crown made hereditary

Ferdinand followed the punishment with structural change: a royal court judge in every town to watch over royal authority, the Jesuit order brought into Bohemia in 1556 to take over public education, and a standing censorship committee over every publication printed or imported. He left the Calixtins' own religious privileges formally untouched, even securing a fresh papal confirmation of their right to receive communion in both kinds, and created a single court of final appeal at Prague to spare his subjects the expense of carrying cases to German tribunals. But the change that outlasted every other was constitutional: in 1562 he obtained the diet's consent to crown his own son Maximilian as heir apparent, converting Bohemia's crown from an elective one into a hereditary one in fact if not yet fully in name. Coxe's own verdict on the whole episode is divided rather than triumphant - praise for ending "the mischiefs of unbridled liberty" paired with regret for the severity of the method, and a note that Bohemia's own once-famous commerce and military reputation began their visible decline under the very reign that finally tamed them.

Obsequium, not obedientiam

expansionDrafted from Coxe, History of the House of Austria, from the Foundation of the Monarchy by Rhodolph of Hapsburgh to the Death of Leopold the Second, 1218-1792 (1847)

Charles's own abdication in 1556 handed Ferdinand the imperial title he had spent thirty years serving as King of the Romans to secure, but even the formal transfer took two years to settle - the electors insisting on a fresh capitulation to fold in the religious peace agreed since Ferdinand's own election, before proclaiming him emperor in 1558. What followed did more to reshape the office itself than anything in the transfer's own paperwork. Custom held that no emperor was fully emperor without a coronation at Rome, and Pope Paul IV - already offended by the religious concessions Ferdinand had granted Protestants in the Peace of Passau - refused his ambassador an audience, dismissed Charles's own abdication as the act of a madman, and declared Ferdinand's election void because electors he judged heretical had taken part in it.

A crown that stopped needing Rome

Ferdinand answered with a deadline: three days for an audience, or his ambassador would leave Rome outright. Paul backed down just far enough to avoid open rupture without withdrawing his claim, and died that same year; his successor Pius IV opened talks instead, and accepted Ferdinand's own compliment of devotion once an aide, working the diplomatic language rather than the substance, slipped the word "obedience" into it. Ferdinand let the phrasing stand without either endorsing or disowning it - he had what he actually wanted, an acknowledged imperial title without the journey to Rome a personal coronation required - and when his own son Maximilian was elected King of the Romans soon after, his own compliment to the pope substituted obsequium, mere deference, for obedientiam outright. Every emperor after Ferdinand followed the same practice: the centuries-old dependence of the imperial title on a Roman coronation ended, in practice, with his own quiet refusal to make the trip.

A referee between two faiths

As emperor Ferdinand kept the same balancing act he had run as king, enforcing the Peace of Passau against encroachment from either side and working, without real success, to reunite the churches outright - pressing Rome, in one memorial the pope himself published to his own embarrassment, to let priests marry and the laity receive communion in both kinds, "the last only transgress a law which is capable of being changed, whereas the first sin against a divine law." Protestant princes meeting at Naumburg in 1560 answered a papal invitation to the reconvened Council of Trent by returning the briefs unopened, refusing even the title of "sons" from a bishop they no longer recognized as a father - and splitting, in the same meeting, between Lutheran loyalists and the Calvinist-leaning faction around the Elector Palatine, a division Coxe notes Ferdinand watched with quiet satisfaction. The reconvened council at Trent closed in 1563 having granted the laity communion in both kinds but refused clerical marriage outright; Ferdinand kept pressing the second point until his own death the following year.

Three sons, three shares

Away from religion, Ferdinand's reign gave Germany a reformed coinage edict that bound every state to strike money bearing its own ruler's name and likeness, a purged and reordered Aulic Council, and faster deputation-diets in place of the empire's unwieldy general assemblies. Confident enough in his own standing that no rival contested his son's succession, he had Maximilian crowned hereditary king of Bohemia and later of Hungary in his own lifetime, securing all three crowns for the next generation before he died. His own testament, signed in 1555, divided the family's hereditary lands rather than keeping them whole: the Archduchy of Austria itself to Maximilian and his own line alone, Tyrol and the outlying provinces to his second son Ferdinand, and Carinthia, Styria and Carniola to his third son Charles - a partition his own three sons signed themselves, and the seed of a family split future reigns would spend decades unwinding.

Ferdinand died on 25 July 1564, sixty-one years old, of a fever Coxe attributes to the chagrin of watching his own efforts at religious reunion fail. Educated on Erasmus's own plan and fluent enough in Spanish, Italian, German and French to correspond directly with scholars across the continent, he left his children a written exhortation to hold to the Catholic faith regardless of what came next - paternal advice that outlived him by less than a generation before his own grandson would turn Bohemia's throne into the opening battlefield of a war that outlasted every Habsburg who started it.

I will sacrifice all worldly interests

expansionDrafted from Coxe, History of the House of Austria, from the Foundation of the Monarchy by Rhodolph of Hapsburgh to the Death of Leopold the Second, 1218-1792 (1847)

Maximilian II grew up in Philip II's own bigoted Spanish court, but absorbed from a secretly Lutheran tutor a religious conviction his family never managed to dislodge. As a young man he kept a Lutheran priest in his own household under the title of secretary, received communion in both kinds from him, corresponded with the leading Protestant princes of Germany, and answered his own father's threats of disinheritance with open defiance: "I will sacrifice all worldly interests for the sake of salvation." His accession in 1564 was dreaded by Catholics and celebrated by Protestants in equal measure - until political calculation did what paternal pressure could not. Maximilian saw the Protestant states divided by their own doctrinal quarrels while the Catholics stood united behind Philip II and the papacy, weighed the succession to the Spanish crown his own family still stood to inherit, and concluded that abandoning the Catholic church outright would cost him more than it gained. He kept his father's own confessor, made a public profession of Catholic faith, and stayed within the church - while never once abandoning the tolerant instincts his own upbringing had given him.

A mediator, not a partisan

That balance defined his whole reign. At his first diet, held at Augsburg in March 1566, he sidestepped an opening religious quarrel by persuading Catholics and Protestants alike to vote emergency funds against the Turks before taking up their grievances - securing far larger subsidies, in men and money, than any diet had previously granted, precisely because both sides trusted him enough to set their dispute aside first. When the religious debate reopened, he refused to take either side directly, simply relaying each faction's complaints to the other until both recognized their own grievances mirrored in their rival's - a studied neutrality that won him, from the pope himself, a subsidy of fifty thousand ducats against the Ottomans, proof that even Rome preferred an impartial emperor to a doctrinally committed rival.

The elector who split the Protestants

Maximilian's even hand was tested again when Frederick III, Elector Palatine, broke from Lutheran orthodoxy toward Calvinism, publishing the Heidelberg Catechism and drawing furious demands from rigid Lutherans - including the Elector of Brandenburg - that the emperor enforce Lutheran worship against him. Catholics saw an opening to split their opponents and pressed for a public reckoning; Maximilian, though personally unable to approve Calvinist doctrine, refused to let Catholics dictate an internal Protestant dispute and left the Protestants to settle the question among themselves. The diet eventually restricted formal toleration to Catholics and adherents of the Augsburg Confession alone - but Maximilian let the Elector Palatine shelter under that same confession's nominal cover rather than expel him outright, extending the Calvinists a toleration that was tacit rather than legal, and holding the empire together without ever fully satisfying anyone inclined to press him for more.

The keys of a burning fortress

John Sigismund's continued raiding gave Maximilian his opening in Hungary: an Austrian force under General Swendy overran Transylvanian positions through the winter of 1565, and when Maximilian offered to resume his father's own tribute in exchange for the existing truce, an aging Süleyman chose provocation instead, mustering for one final campaign. He reached Belgrade in the spring of 1566, received John Sigismund with the same regal honours he had shown him before, and declared that despite his own failing health he had taken the field again to "chastise the house of Austria, or perish under the walls of Vienna."

Count Zrínyi's sally

Süleyman's march up the Danube turned aside when the garrison of a small marsh fortress called Szigetvár killed one of his own favourite pashas in a raid. Count Miklós Zrínyi held the town with barely fifteen hundred men, and for thirty-four days matched the endurance Güns had shown a generation before - the Turks forced across the surrounding marsh on causeways of their own construction, raising earthworks for their batteries, launching assault after assault. Zrínyi's garrison, reduced at last to six hundred men and an inner fort already burning around them, chose a final sortie over surrender: Zrínyi took the keys of the fortress, armed himself with his own ancestral sabre, and led what remained of his men out to die fighting rather than be overrun. Almost none survived it. The Turks took the ruin at a cost Coxe puts at twenty thousand men - and Süleyman himself did not live to see the victory, dying on 4 September 1566 of fatigue and the marsh's own foul air, his death concealed by the grand vizier until the new sultan Selim could reach the army and order it home.

A peace that cost one fortress and gained a province

Maximilian, who had kept his own main force on the defensive near Győr rather than risk a battle that could have opened Hungary outright to John Sigismund, used Süleyman's death to negotiate from strength: an armistice concluded in May 1567 left each side in possession of what it actually held, costing Maximilian only Szigetvár and Gyula while extending his own territory some two hundred miles beyond the Tisza. John Sigismund refused to be bound by a peace he had no part in making and kept intriguing among Hungary's own magnates, but died in 1571 without ever reopening a war Maximilian's own truce with the sultan had made unwinnable for him.

A crown he hesitated too long to take

Poland's own elective throne fell vacant the same decade, and Maximilian's own hesitation - weighing whether to take the crown himself or transfer it to his son Ernest, wary of the war with the Turks a Polish throne might invite, unwilling to accept the onerous terms Poland's own nobility demanded - let a faster rival, Stephen Báthory, marry the Polish princess Anne and take the crown outright in May 1575. Maximilian signed the same terms only after his rival already held them, and was still trying to rally Sweden and Denmark against Báthory when his own health, already failing, gave out. He died at Regensburg on 12 October 1576, fifty years old, in the middle of a diet whose business closed the same day - a reign contemporaries in every one of his kingdoms, Catholic and Protestant alike, praised with a rare unanimity Coxe records at length: a Bohemian embassy's own tribute called his subjects "as happy under his government as if he were our father," and Germany revived for him the old Roman title Delight of Mankind.

Rudolf II inherited an empire Maximilian's own tolerance had left calm, and spent his reign undoing that calm one concession at a time. Raised from age twelve at Philip II's own Spanish court and educated by Jesuits trained to fix rather than open a young mind, he emerged devoted to his mother's rigid Catholicism, absorbed in alchemy and judicial astrology rather than government, and unwilling to extend the informal toleration his own father had allowed Vienna's Protestant nobility. Where Maximilian had quietly let burghers attend Lutheran services held for the nobility, Rudolf enforced the letter of the old law, confined Protestant worship among the nobles and knights to a room too small for any other audience, and stripped Vienna's most popular Protestant preacher of his office - lighting, in Austria, Hungary and above all Bohemia, the same resentment his father had spent a reign defusing.

A brother made king in Hungary

Rudolf's own incapacity gave his ambitious younger brother Matthias the opening his father-in-Habsburg-terms had never had. When Hungary's own nobility, exhausted by Rudolf's mismanagement of the Ottoman frontier and his refusal to confirm their privileges, turned openly to Matthias instead, he accepted their allegiance, negotiated a favorable peace with the Turks on his own authority, and in 1608 forced Rudolf to cede him Hungary, Austria and Moravia outright, keeping only Bohemia and the imperial title for himself. Matthias returned to Vienna intending to crush the Protestant unrest his own rise had depended on, but found himself needing Moravian mediation to hold his new territories together, and on 19 March 1609 confirmed the same religious privileges for Austria's Protestants that Maximilian had once granted and Rudolf had revoked.

The Letter of Majesty

Bohemia's own Protestants, watching their neighbors win by pressure what petitions had never obtained, organized their own defiance: a diet convened without royal permission in May 1609, an armed militia under Count Thurn raised within days, and an alliance with Silesia's own Protestant estates that put several thousand troops in the field before Rudolf could respond. Isolated, humiliated, and unable to summon help from a brother he had already lost most of his territory to, Rudolf capitulated on 5 July 1609 with the document history remembers as the Letter of Majesty - full freedom of worship for anyone receiving communion in both kinds, the right to build churches and schools, an elected Protestant consistory, and a clause voiding any future royal act that contradicted it. Bohemia's Protestants held their arms until Silesia secured the same terms, then stood down; for a brief interval, Coxe notes, Catholic and Protestant villages returned to worshipping side by side in something like the tolerance Maximilian's reign had once made ordinary.

An abdication torn under his own feet

The concession bought Rudolf no real peace. Matthias, backed by an army and by Bohemia's own restless nobility, forced the issue a second time in 1611: Rudolf, on hearing his envoys had failed to hold Prague for him, was said to have flung open his own window and cried, "Prague, unthankful Prague, who hast been so highly elevated by me; now thou spurnest at thy benefactor." He refused for as long as he could to sign the instrument releasing his own subjects from their oath of allegiance, and when finally compelled, blotted the document and snapped the pen underfoot rather than complete it cleanly. Matthias was crowned King of Bohemia on 23 May 1611 under guard, in a city whose gates stayed shut against any last attempt on Rudolf's own behalf. Rudolf lived barely a year longer, dying in Prague in January 1612 in the sixtieth year of his life, reportedly welcoming death as a release from "the calamities of human nature" after a reign that had converted his father's hard-won religious balance into the standing grievance the whole House of Austria would spend the next three decades fighting over.

An ancient custom of Bohemia

expansionDrafted from Coxe, History of the House of Austria, from the Foundation of the Monarchy by Rhodolph of Hapsburgh to the Death of Leopold the Second, 1218-1792 (1847)

Matthias, childless and aging, spent his own last years maneuvering to secure the succession for his cousin Ferdinand of Styria - a devout Catholic already notorious for suppressing Protestant worship in his own duchies - and had him crowned King of Bohemia in 1617 over Protestant objections that his own Letter of Majesty guarantees would not survive such a successor. Those fears proved founded almost immediately: when Bohemia's Protestant estates complained that two churches built on royal land had been shut down in violation of the Letter, the council of regents governing in Matthias's name - guided, in the delegates' own eyes, chiefly by two hardline Catholic councillors, William Slavata and Jaroslav Martinic - sent back an answer they read as an outright denial of their rights.

Out the window

A delegation of Protestant nobles led by Count Thurn confronted the council directly at Prague Castle on 23 May 1618, demanding to know who had actually drafted the offending reply. When persuasion failed to satisfy them, one delegate invoked what Coxe records as "the ancient custom of Bohemia" and called for the offending councillors to be thrown from the window; Martinic went first, into the castle ditch, followed - after the delegation's own momentary horror nearly broke their resolve, and Thurn rallied them back to the act - by Slavata and his secretary. All three survived an eighty-foot fall, saved by the moat's own soft mud and a broken landing rather than any mercy from the crowd still firing on them from above. Thurn moved immediately to make the act irreversible, riding through Prague to declare to the gathered crowds that "the die is thrown, it is too late to recall what is past," and within days the estates had revived their old confederacy, elected thirty directors, expelled the Jesuits and the archbishop, and appealed to every Protestant power in reach for support.

A king who stayed at dinner

Matthias's death in 1619 left Ferdinand to inherit a revolt already in open war: Bohemia's estates deposed him outright and offered the crown instead to Frederick V, the young Calvinist Elector Palatine, whose acceptance turned a regional rebellion into a contest for the whole religious balance of the empire. Ferdinand, elected Holy Roman Emperor in the middle of the crisis, spent a year assembling the coalition that would decide it - the Catholic League under Bavaria's Duke Maximilian, the Elector of Saxony detached from the Protestant cause with the promise of Lusatia, and support from Spain and the pope - while Frederick's own popularity in Bohemia curdled as quickly as it had bloomed. When the two armies finally met outside Prague at the White Mountain on 8 November 1620, Frederick was at the palace hosting a dinner for the English ambassador rather than with his own troops; by the time repeated couriers convinced him to ride out, his army had already broken, and he watched its final collapse from the city ramparts before ordering the gates opened for the fleeing survivors. Offered a chance to hold Prague itself behind seventeen intact battalions and reinforcements still in the field, Frederick chose flight instead, leaving the Bohemian crown and regalia abandoned in the marketplace and slipping out of the city by night - earning, from the war he had accepted a crown to fight, the lasting nickname "the Winter King."

The reckoning

Prague surrendered the next morning, and for three months Ferdinand's own restraint let former rebels believe the worst might be over. It was not. Forty of the revolt's leaders were arrested in a single night on 21 January 1621; after four months' imprisonment, twenty-three were publicly executed in Prague's own old town square, their property confiscated outright, and the rest banished or imprisoned for life. A mandate of what Coxe calls "more than inquisitorial severity" then ordered every landholder who had taken part in the rising to confess their own guilt under threat of still harsher punishment if convicted later without having done so - and in the panic that followed, more than seven hundred nobles and knights, guilty and innocent alike, added their own names to the list rather than risk the alternative. The rebellion that had begun with two councillors thrown from a castle window ended with the confiscation of most of the Bohemian nobility's own land, the Letter of Majesty it had been fought to defend torn up by Ferdinand's own hand, and a religious and political settlement imposed on Bohemia that would hold, in one form or another, for the better part of two centuries.

My hour is written in heaven

Victory at White Mountain emboldened Ferdinand II past the point his own coalition could sustain. Flush with conquered Bohemia and a war that seemed decided, he issued the Edict of Restitution on 6 March 1629, ordering every piece of church property secularized since the Peace of Passau in 1552 - two archbishoprics, a dozen bishoprics, hundreds of monasteries - returned to Catholic hands outright. The edict alarmed Protestant and Catholic princes alike, who saw in it an emperor no longer bound by the empire's own settled compromises, and it gave Sweden's King Gustavus Adolphus the pretext he needed to carry his own army into Germany the following year, landing on the Pomeranian coast to defend a Protestant cause his own conquests would soon eclipse in scope.

A general dismissed, then recalled

Ferdinand had already been forced to dismiss the general most responsible for his run of victories, Albrecht von Wallenstein, whose private army and outsized ambition had alarmed German princes on both sides of the religious divide. Gustavus's own advance - a rout of the Catholic League's forces at Breitenfeld in 1631, a march that carried Swedish troops as far as the Rhine and into Bavaria itself - left Ferdinand no real alternative but to recall the one commander capable of matching him. Wallenstein returned to raise a fresh imperial army from nothing within months, and the two greatest commanders of the war finally met in open battle outside the small Saxon town of Lützen on 6 November 1632.

Lützen

Fog delayed the fighting past midday, and when the lines finally engaged, Gustavus led a cavalry charge into a gap in his own line without adequate escort and was shot from his horse in a confused melee his own army barely noticed until his riderless mount reappeared. The Swedes fought on without knowing their king had already died, and carried the field by nightfall regardless - Wallenstein's army broke and retreated, leaving Sweden the tactical victor of a battle that cost it the one commander no other general in Europe could yet match. Coxe's own eulogy calls him "one of the greatest monarchs who ever adorned a throne," a soldier who told those urging him to spare himself in battle that "my hour is written in heaven, and cannot be reversed on earth." His body, stripped and left under a heap of the slain, was carried first to Naumburg and eventually home to Stockholm.

A general too powerful to keep

Gustavus's death did not end the war Wallenstein's own victories had briefly seemed to be winning back for Ferdinand. Wallenstein's own conduct after Lützen - opening independent negotiations with Sweden and Saxony, holding his army apart from the emperor's own strategic direction - convinced Ferdinand's court that a general who had once raised and paid an entire army on his own credit could no longer be trusted with one. Officers loyal to the emperor assassinated Wallenstein at Eger in February 1634, ending, by violence rather than dismissal, the career of the one commander whose private resources had kept Ferdinand's war effort solvent through its hardest years - and opening a command structure the emperor's own son, the future Ferdinand III, would take over in the war's final, exhausting phase.

The definitive year

expansionDrafted from Coxe, History of the House of Austria, from the Foundation of the Monarchy by Rhodolph of Hapsburgh to the Death of Leopold the Second, 1218-1792 (1847)

Wallenstein's assassination and Gustavus's death did not shorten a war that had already outgrown its own original religious quarrel. Ferdinand III, who succeeded his father in 1637 with a reputation for mildness and prudence Coxe judges better suited to peace than to war, spent his own reign managing a contest that had become a straightforward struggle between the Bourbon and Habsburg dynasties, fought increasingly by Swedish and French armies on German soil for stakes that had little left to do with the Bohemian succession that started it. Sweden's own armies reached the outskirts of Vienna and besieged Prague in the war's final years; France, allied with Sweden since Richelieu's own intervention, fought as much to weaken the Habsburgs generally as to defend German Protestants in particular. By the 1640s exhaustion had outpaced ambition on every side, and negotiations opened at two neighboring Westphalian towns, Osnabrück for the empire's own religious and internal settlement, Münster for the wider peace with France - a division that let Catholic and Protestant power in Germany settle its own account separately from the international one.

What changed hands

The peace signed in 1648 redrew both the map and the rulebook. France gained sovereignty over Alsace and confirmed its hold on Metz, Toul and Verdun; Sweden took Western Pomerania and a cash indemnity, along with three votes in the imperial diet; Brandenburg, Bavaria, Mecklenburg and Hesse-Kassel each received territorial compensation for their own losses or services; and the Palatinate was split, its restored branch given a newly created eighth electorate rather than displacing Bavaria from the one it had held since 1623. Every prince and state stripped of rights since the Bohemian revolt of 1619 was formally restored to its prewar standing, and the Swiss Confederation was released from imperial jurisdiction outright, closing three centuries of nominal subjection that had been a fiction since Basel's own day.

A settlement built on a fixed date

The religious terms mattered more than any territorial line. Calvinists won the same legal standing Lutherans had held since 1555, ending the narrower peace that had recognized only two confessions; the disputed question of secularized church property was settled not by principle but by a fixed calendar date, 1 January 1624, chosen as the "definitive year" whose ownership pattern would simply be restored and then frozen

• a compromise that asked neither side to concede the argument, only to stop refighting it. Ferdinand's own Edict of Restitution, the act that had reignited the war in 1629, was effectively undone by the same stroke.

Ferdinand III lived nine more years after the peace he had spent a decade negotiating toward, working to rebuild imperial authority within the settlement's own new limits before his death in 1657. His own successor, Leopold, inherited a Habsburg Monarchy that had held Bohemia, Hungary and the Austrian lands together through Europe's longest and costliest religious war, at the price of a Germany now formally, permanently divided among rival faiths and a France newly established, by treaty, on the Rhine's own left bank.

The standards on the Kahlenberg

Leopold I's own reign settled into a long, grinding contest over Hungary rather than the set-piece wars that had defined his predecessors. A Protestant and noble rebellion under Imre Thököly, fed by Leopold's own broken promises of religious toleration and backed by Ottoman support, controlled Upper Hungary by 1682 and drew the sultan directly into the conflict the following year: Grand Vizier Kara Mustafa marched on Vienna with an army Coxe puts at two hundred thousand men, while Leopold's own court could barely muster forty thousand to meet it. When the Duke of Lorraine's outnumbered forces fell back on the capital, they found a city already emptying - Leopold and his court had fled the night before amid what Coxe records as open curses against the ministers and Jesuits blamed for provoking a war the population had been left undefended against.

A city that emptied and a city that held

What saved Vienna was not the emperor's own presence but Lorraine's preparations and the defense mounted by the city's governor, Rüdiger von Starhemberg: suburbs demolished for clear fields of fire, walls hastily repaired, citizens and students drilled alongside the garrison. The Ottoman siege opened on 14 July 1683 and ground on for two months while Vienna's own defenders, reduced by disease and constant assault, watched the outer works fall one by one with no relief in sight - German reinforcements slow to muster, the Polish army still gathering on the Silesian frontier. Leopold himself, reduced to pleading rather than commanding, wrote directly to King John Sobieski of Poland to march ahead of his own main force: "however inferior in number, your name alone, so terrible to the enemy, will ensure a victory."

Rijksmuseum, Amsterdam · Coxe, History of the House of Austria, from the Foundation of the Monarchy by Rhodolph of Hapsburgh to the Death of Leopold the Second, 1218-1792 (1847) · Rijksmuseum · CC0

The twelfth of September

Sobieski answered by force-marching a vanguard of three thousand cavalry across Silesia and Moravia before his own full army had assembled, and on 12 September the relief force appeared on the heights of the Kahlenberg above the city - the sight of Christian standards on the hillside reviving a garrison that had all but given up hope of rescue. The combined imperial and Polish attack broke the already-exhausted besiegers within hours; the grand vizier abandoned his own camp in the night rather than risk annihilation, leaving behind artillery, provisions and a standard believed at the time to be the Prophet's own banner. Sobieski, writing to his own queen with the plunder still being catalogued, joked that "the grand vizier has left me his heir, and I inherit millions of ducats."

Two very different entrances

Vienna's own gratitude fell entirely on the Polish king. He entered the city the next morning to crowds that hailed him as father and deliverer, struggling to touch his horse or his garment; Leopold's own return three days later, by contrast, drew no cheers at all - he walked to the cathedral on foot, carrying a candle, in what Coxe reads as genuine humility rather than performance, aware the city's gratitude belonged to someone else. The military campaign that followed the relief pushed the Ottomans out of most of Hungary within a decade and a half: Leopold's own diet at Pressburg declared the Hungarian crown hereditary in the House of Austria in 1687, ending the elective kingship that had shaped two centuries of contested Habsburg succession there, and Prince Eugene of Savoy's decisive victory at Zenta in 1697 forced the sultan to the negotiating table. The Peace of Karlowitz, signed in 1699, confirmed nearly all of Hungary and Transylvania under Habsburg rule for the first time since the disaster at Mohács a century and three-quarters before - closing, in Leopold's own reign, a contest that had outlasted seven Habsburg rulers before him.

A crown worn three days

Spain's own throne fell vacant in 1700 when Charles II died without an heir, and Leopold I answered the resulting Bourbon claim by pressing his own family's rival right through his second son, the Archduke Charles - a dispute that widened almost immediately into a European war, since neither England nor the Dutch Republic would accept a single Bourbon crown spanning both France and Spain. Charles himself, not yet eighteen, was proclaimed King of Spain at Vienna in 1703 and shipped off through England on his way to the Iberian peninsula; Queen Anne received him at Windsor for three days, and a contemporary account Coxe quotes admired a gravity "beyond his age, tempered with much modesty" in a young man who managed to seem pleased with everything at court without smiling once. The war that followed his own claim ground on across the Netherlands, Germany, Italy and Spain itself for a decade, carried in the north chiefly by the Duke of Marlborough's own generalship and in the empire's own name by Prince Eugene of Savoy, without ever fully settling the Spanish succession Charles had gone to Madrid to claim.

An emperor gained, a Spanish crown lost

Leopold's own death in 1705 passed the imperial title and the Austrian hereditary lands to his elder son Joseph I, leaving Charles to fight on as the Austrian claimant to Spain alone. Joseph's reign lasted barely six years, cut short by smallpox in 1711, and left no son to inherit - only two daughters, and a brother still contesting a Spanish throne an ocean away. The war's own logic collapsed the moment Charles became the only plausible heir to the whole Habsburg inheritance: the same coalition that had gone to war to stop one family uniting France and Spain now balked at uniting the empire and Spain under Charles instead, and English support for his Spanish claim evaporated almost overnight. Charles inherited Austria, Bohemia and Hungary as Charles VI, and the Peace of Utrecht in 1713 settled Spain itself on the Bourbon claimant his own war had been fought to prevent

• leaving Charles with the empire his brother's death had handed him, and the Southern Netherlands and Habsburg Italy as compensation for a Spanish throne he had spent a decade trying to reach in person and never sat on for more than a few contested years.

A daughter guaranteed by Europe

contractionDrafted from Coxe, History of the House of Austria, from the Foundation of the Monarchy by Rhodolph of Hapsburgh to the Death of Leopold the Second, 1218-1792 (1847)

Charles VI came to the Austrian throne through a family compact that had never actually settled who should inherit if a Habsburg emperor died without a son - only that Joseph's own daughters would take precedence over Charles's if both brothers left none. Charles reversed that order almost as soon as he was crowned, and on 2 August 1718 issued the decree known as the Pragmatic Sanction, entailing the succession first on any daughters of his own, ahead of his late brother's. The reversal mattered because it was never merely theoretical: his only son died in infancy, and three daughters - Maria Theresa, Maria Anne and Maria Amelia - survived him instead. Charles forced his own nieces to renounce their competing claims as the price of their marriages to the Electors of Saxony and Bavaria, but distrusted paper renunciations enough to make something larger his life's central project: securing every major European power's own guarantee that his daughter would inherit intact.

The price of a guarantee

That pursuit shaped two decades of Habsburg foreign policy, and Coxe's own verdict is blunt - Charles sacrificed nearly every other interest of his reign to it. He bought Spain's own acceptance of the succession by conceding Habsburg claims to territories the War of the Spanish Succession had only just secured; he bought Britain's support with commercial concessions that crippled his own newly founded Ostend trading company; he bought France's eventual guarantee, in 1738, at the cost of the whole War of the Polish Succession, ceding Lorraine outright to the deposed Polish king and, through him, to France on his death. One by one, the great powers of Europe put their own names to a guarantee of an inheritance none of them had any real stake in honoring once Charles was no longer alive to enforce it.

A daughter who inherited a paper promise

Charles never took the one step his own ministers, his wife and the British court all pressed him toward: securing his son-in-law Francis of Lorraine election as King of the Romans while he still lived, which would have kept the imperial title itself inside the family regardless of what happened to the female succession elsewhere. He judged his own wife's death more likely than his own and held out hope for a second marriage and a male heir that never came. He died in 1740, and Maria Theresa, not yet twenty-four, inherited the full Habsburg patrimony under a Pragmatic Sanction every neighboring power had formally guaranteed - a guarantee that, within weeks of her father's death, proved worth exactly as much as the armies Prussia's own new king was already marching to test it against.

A guarantee worth nothing

Every European power had put its name to the Pragmatic Sanction while Charles VI lived. Weeks after his death, Frederick II of Prussia tested exactly what that guarantee was worth: he marched twenty thousand men into Silesia in December 1740, offering Maria Theresa an alliance and his own support for her husband's imperial election in exchange for the province outright, and warning through his envoys that he would have Silesia one way or another. Maria Theresa's own reply, delivered without hesitation, set the tone for the whole reign that followed: sooner lose her last man and cede her last town than surrender what her own signed guarantees had promised her. France, Bavaria and Spain read Prussia's opening move as an invitation, and by 1741 what had started as a single land grab had become a general War of the Austrian Succession, with a Bavarian elector crowned Holy Roman Emperor in Frankfurt while Austrian troops were still fighting to hold Vienna itself.

Silesia lost, a throne held

Maria Theresa never recovered Silesia - the province stayed Prussian through the war's formal end at Aix-la-Chapelle in 1748 and through the Seven Years' War that reopened the same quarrel between 1756 and 1763, despite an alliance with France and Russia that briefly seemed capable of dismembering Prussia outright before Russia's own withdrawal from the coalition saved Frederick's kingdom at its lowest point. What Maria Theresa did hold, against every expectation the Prussian gambit had rested on, was everything else: the Pragmatic Sanction's larger promise survived intact, her husband Francis was elected emperor in 1745, and the Bohemian and Hungarian estates whose loyalty had been anything but assured rallied to a young queen most of Europe had expected to be a pushover.

Centralizing a patchwork state

The wars that defined her reign's first two decades pushed Maria Theresa toward reforms no purely peaceful Habsburg monarch would have needed: a standing army rebuilt and professionalized, a unified system of taxation that for the first time reached the nobility and clergy rather than falling on the peasantry alone, a centralized bureaucracy replacing the patchwork of provincial estates that had slowed Ferdinand I's own great-great-grandchildren for two centuries, and a public school system extended, by decree, into the countryside. Much of the practical work fell to ministers like Prince Kaunitz and Haugwitz rather than to Maria Theresa personally, but the direction - a state that could tax, conscript and educate more of its own population directly, rather than through the intermediary privileges of nobles and towns - was hers.

Forty-one years

She died on 29 November 1780, sixty-three years old, after a decline Coxe describes at length and with evident admiration: dictating state business between attacks of illness almost to the end, and answering her own son's plea that she rest with the reply that she would soon stand before the judgment of God and saw no reason to spend her last hours asleep. Coxe's own summary balances real affection against real criticism - a ruler who combined public generosity with private economy and genuine popular devotion, but whose own religious intolerance, most visibly toward Bohemia's Protestants and Austria's Jews, "cast a shade on her memory" even by his own admiring account. Of the sixteen children she bore Francis, her own son Joseph, already her co-regent for the final fifteen years of her reign, succeeded her outright - inheriting a monarchy larger, more centralized and more fiscally capable than the one she had nearly lost to Prussia in the first weeks of her reign.

A sovereign who never carried a project

Joseph II had spent fifteen years as his mother's co-regent chafing against a share of power that left him touring Europe's arsenals, courts and charitable institutions while real authority stayed in Maria Theresa's own hands. When he inherited the monarchy outright in 1780, he moved to remake it faster than any Habsburg before him: an Edict of Toleration extending legal protection to Protestants and Orthodox Christians in Catholic-only hereditary lands, and full civic rights to Jewish subjects previously barred from most trades and professions; the abolition of serfdom across the Bohemian and Austrian lands, converting peasants bound to their lords' own soil into free subjects who owed rent rather than labor and person; the dissolution of contemplative monasteries whose revenue he redirected to parish priests and charitable institutions; German imposed as the single administrative language across a monarchy that had never had one; and a codified, more humane criminal law that abolished torture and sharply limited capital punishment.

Reform issued faster than it could be enforced

Joseph's own method undid much of what his reforms might have achieved. Frederick the Great's own verdict, which Coxe quotes with evident agreement, called his rival's mind "a confused magazine of despatches, decrees, and projects" - laws issued before the machinery to enforce them existed, then revised or reversed by the next courier before the first had taken effect. Hungary's own nobility, whose privileges and Latin administrative language Joseph overrode without ever having himself crowned with St. Stephen's crown, resisted almost every one of his edicts outright; the Austrian Netherlands, whose own constitutional liberties he dismantled with the same impatience he brought to Vienna's bureaucracy, rose in open revolt in 1789 and drove his own garrisons out of Brussels within months.

A revolt he could not put down

The Netherlands rebellion broke Joseph as much as any military defeat could have. Already weakened by tuberculosis and by a costly, largely fruitless war against the Ottomans undertaken more from personal rivalry with Catherine of Russia than from any Austrian interest, he wept openly on hearing Brussels was lost, and spent his final months watching every power he might have appealed to for help - Prussia, England, the Dutch Republic - decline to lift a hand for a ruler each had reason to see humbled. He died on 20 February 1790, not yet fifty, reportedly composing his own epitaph in the final weeks: "Here lies a sovereign, who with the best intentions never carried a single project into execution." Twice widowed and without a surviving child, he was succeeded by his younger brother Leopold, who inherited a monarchy whose Netherlands provinces were in open revolt, whose Hungarian nobility was in a state of organized refusal, and whose Turkish war was still unfinished - the practical wreckage of a decade spent trying to remake, by decree, what Maria Theresa's own reign had built more slowly and more durably.

A throne no longer tottering

Leopold II inherited, in his own brother's final weeks, a monarchy in open crisis on every front: the Austrian Netherlands functioning as an independent republic after driving out Joseph's own garrisons, Bohemia and Lower Austria's estates in open remonstrance against a new land tax, and a faction in Hungary arguing that Joseph's own refusal to be crowned had voided the Habsburg succession outright and returned the crown to the nation's own choice - "Hungary," as Coxe records the claim, "has no need of an Austrian king." Prussia backed every one of these fractures deliberately, sheltering Hungarian dissidents at Berlin and allying with the Ottomans in the hope of stripping Galicia from Austria while the monarchy was still reeling.

A year that undid a decade of crisis

Leopold answered with negotiation rather than force on every front at once. He met Prussia at the Convention of Reichenbach in 1790, trading territorial concessions for an end to Prussian meddling in the Netherlands and Hungary; he restored the privileges Joseph had stripped from Hungary and Bohemia's own estates, defusing the succession argument by having himself properly crowned in both kingdoms; and he recovered the Netherlands from its short-lived republic through negotiation rather than reconquest. Within a single year, Coxe judges, Leopold had relieved his country of foreign war and internal revolt alike and left a throne that had been tottering at his accession standing on firmer ground than his own brother had managed to build in a decade of continuous reform.

A death that opened a different war

Leopold turned his own attention last to France, where his sister Marie Antoinette's own safety and the French National Assembly's increasingly radical dismantling of the monarchy demanded some response. A declaration warning against foreign interference in France's internal affairs, issued jointly with Prussia, only inflamed the revolutionary factions in Paris further - Leopold's own name was met with insult in the Assembly, and calls for war against Austria spread through the city before he could develop any policy beyond the declaration itself. He never lived to see where that confrontation led: seized by dysentery on 27 February 1792, he died within three days, forty-four years old, leaving a throne he had spent barely eighteen months securing to his own son.

Francis succeeded to the hereditary dominions immediately and gained the imperial crown that July - inheriting, in the same year as his own accession, a war with revolutionary France that would run, in one form or another, for the next generation, reshaping the empire his family had spent five centuries building into a form none of his predecessors would have recognized.

A scattered empire, easy prey

contractionDrafted from Lingelbach, Austria-Hungary (1910)

Francis II inherited, at twenty-four, a monarchy second only to Russia and France in size, but scattered across six historically distinct blocs of territory - the Austrian and Bohemian hereditary lands, the Kingdom of Hungary with Croatia, Slavonia and Transylvania, Galicia, the Milanese and Mantuan districts cut off from everything else by Venetian territory, and the Austrian Netherlands standing entirely alone on the far side of Germany. That scattering, rather than any single weakness in its own army or treasury, made the monarchy what Lingelbach calls "an easy prey to an enemy": whichever outlying province an opponent could reach first would be the one that fell first, and the Netherlands, most isolated of all and least attached to Habsburg rule, proved exactly that.

The Low Countries lost twice over

War with revolutionary France broke out before Francis had even been elected emperor - the French declared war on him simply as King of Bohemia and Hungary - and the fighting bore out the monarchy's own geography almost immediately. A French victory at Jemmappes in November 1792 carried the Austrian Low Countries as far as Luxembourg into French hands; an Austrian counterattack the following spring won them back only long enough for a second French victory at Fleurus in June 1794 to take them for good. Prussia, nominally Austria's ally, gave what Lingelbach calls lukewarm support throughout, more absorbed in partitioning Poland than in holding the coalition together, and pulled out of the war entirely in 1795 by signing a separate peace at Paris - leaving Francis unable even to avenge his own aunt Marie Antoinette's execution, let alone hold the Netherlands he had already lost.

Poland instead of Belgium

Denied any real compensation from France, Francis turned to the one place still open to Habsburg expansion: what remained of a Poland Russia and Prussia were already dismantling. The third and final partition, agreed with both powers, gave Austria the palatinates of Sandomierz and Lublin along with portions of Kraków, Mazovia, Podlachia and Brest - territory organized as the new province of Western Galicia, a substitute Lingelbach frames plainly as compensation for a Belgian loss no diplomacy had been able to reverse.

A treasury and a press both mortgaged to the war

Eight years of continuous fighting drained a monarchy that had never been wealthy to begin with. Francis mortgaged his own private estates to raise money; paper currency multiplied, forced loans were raised across every province, and Joseph II's own internal free-trade reforms were undone as customs barriers went back up between Hungary and the rest of the Austrian lands. Domestic policy moved in the opposite direction from his uncle's reforming instincts on nearly every other front too: press censorship passed from university professors to the police outright, and a tax on printed matter was added on top of it - a government that met revolutionary ideas from across its own western border by tightening exactly the freedoms Joseph had spent a decade extending. Not every reform stopped: serfdom was abolished in Galicia in 1799, roads were pushed through Carniola, Croatia, Bohemia and Moravia, and the legal code Maria Theresa had begun continued to grow

• but Francis, in Lingelbach's own phrase, did nothing at all for public instruction, judging the risk of educated subjects not worth the reward.

Only one Vienna

endDrafted from Lingelbach, Austria-Hungary (1910)

Peace with France in 1801 stripped the House of Habsburg-Lorraine of every remaining German possession beyond the archduchy of Austria itself, leaving Francis II's own imperial title over Germany real in theory alone. What was left of his actual power lived entirely in his own hereditary dominions - the hereditary Austrian provinces, Bohemia, Hungary, Galicia and Venetia, the last two held by conquest rather than by the older claims of inheritance or compact that secured the other three. No single title captured that patchwork, and Francis judged the old styles - archduke of Austria, king of Bohemia and of Hungary - no longer adequate to a ruler of a monarchy this size, nor impressive enough to stand beside the courts of Europe.

An answer to Napoleon's own coronation

Napoleon's own assumption of the imperial title in France gave Francis the occasion he needed. He announced his decision in a public letter whose language Lingelbach preserves directly: bound already, "by the grace of God and the choice of the electors," to the Romano-German imperial dignity, Francis declared his wish "to strive for the maintenance of complete equality between our imperial title and hereditary dignity and those of the other sovereigns," and, following the precedent of Russia's own imperial title and now Napoleon's, resolved to take for himself and his successors "the hereditary title of emperor of Austria, after the name of our house" - while promising that every one of his kingdoms and provinces would keep its own separate title, constitution and privileges undisturbed.

A title that changed nothing and everything

The new style was recognized by every foreign court without objection, and Lingelbach is careful to note what it did not do: it altered no province's actual government, Francis and his successors continued to be separately crowned kings of Bohemia and Hungary exactly as before, and no Austrian sovereign has ever undergone a coronation specifically as Emperor of Austria. What it did do was state outright, for the first time, the historical unity the Pragmatic Sanction had only implied - a step Lingelbach judges Charles VI himself would never have dared take explicitly in his own century. At thirty-six, already aged by eight years of continuous war into what Lingelbach calls a timid and suspicious man with little interest beyond natural science and music, Francis had spent his reign losing the Netherlands, ceding ground to Napoleon, and watching his own uncle's reforms rolled back one by one - and closed its opening chapter not with a victory, but with a new name for the same scattered inheritance seven generations of his family had spent nearly three centuries assembling piece by piece from a dead king's crowns at Mohács.
