A Slavic empire built by a Frankish-installed prince who turned independent, whose ruler Rostislav brought in Cyril and Methodius to build a Slavic-language Church free of German clergy, and which reached from Kraków to Magdeburg under Svatopluk before its own princes' quarrels let the Magyars conquer it outright.

Louis the German deposes MojmirSuccession crisis
A Frankish army under Louis "the German" deposed Mojmir and set his own nephew Rostislav on the Moravian throne in his place - a client appointment that backfired badly, since the man the Franks had chosen to obey them would spend the following decade trying to pry his own country loose from their grip instead.

Cyril and Methodius arriveConversion
Answering Rostislav's own request for teachers who could preach "in our own language," the Byzantine Emperor sent the brothers Constantine and Methodius, who built a Slavic-language liturgy and Church independent of the German clergy Rostislav distrusted - a mission with as much political purpose, in the source's own judgment, as religious.

Svatopluk turns on his own captorsBattle
Svatopluk, who had betrayed his own uncle Rostislav to the Franks the previous year and was then imprisoned in turn by the same Germans he had served, broke free, put himself at his own countrymen's head, and wiped out the pursuing force - both Austrian margraves dead among the casualties - to become Moravia's sole and unchallenged ruler.

The Treaty of ForcheimTreaty
After Svatopluk carried the war into Germany itself, King Louis agreed terms that secured Svatopluk his conquests in northern Hungary under nominal German overlordship alone - a peace that let Moravia's own empire expand toward the reach it held at its height, from Kraków to the Bohemian interior.

Svatopluk's death and the empire's ruinSuccession crisis
Svatopluk's death broke Moravia's own unity: his sons Mojmir and Svatopluk fell to fighting each other over the succession, and the Bohemian prince Spytihněv seized the resulting disorder as his own chance to break free of Moravian control and put an independent Přemyslid back in charge of Bohemia - the largest single territory Svatopluk's own empire ever lost.

The Magyar conquestCatastrophe
A combined German and Slavic force meant to check the Magyar advance instead broke apart at Pressburg, and the victors went on to occupy Moravia itself for the next half-century and more - erasing, in a campaign whose own date the source cannot pin down with confidence, an empire that had once stretched from the Elbe to the Carpathians.

A nephew installed by Frankish spears
formationDrafted from Lützow, Bohemia: An Historical Sketch (1920)
The Morava valley's earlier history is as obscure as Bohemia's own,
sharing what evidence there is of Avar conquest and, later, a share in
the short-lived realm the Frankish merchant Samo built after freeing
the Slavic tribes from Avar rule in the seventh century. Real
documentation begins only in the ninth century, with a ruler named
Mojmir governing Moravia with what the sources credit as genuine
ability, uniting scattered tribes under a single dominion for the
first time - the "real founder," in Lützow's own words, of a Moravian
empire that would for a time include Bohemia as well.

A puppet who would not stay one
Mojmir's success drew the attention of the Frankish king Louis "the
German," who sent an army into Moravia in 846, deposed him, and
installed his own nephew Rostislav as ruler in his place - a
straightforward act of imperial engineering, meant to leave Moravia in
Frankish hands through a client prince. The Germans then turned their
army against Bohemia as well, but were defeated there, opening thirty
years of intermittent war between Germany and the Bohemian lands that
Lützow judges of little interest to English readers beyond the fact of
its length. Rostislav proved a poor investment for his Frankish
patrons: rather than governing as their instrument, he spent his own
reign working to free Moravia from exactly the German supremacy that
had put him on the throne, and the mission he would soon send to
Constantinople was the clearest expression of that ambition.
Teachers who speak our own language
expansionDrafted from Lützow, Bohemia: An Historical Sketch (1920)
In 862 Rostislav sent envoys to Constantinople with a request to the
Byzantine emperor Michael: "Our people have rejected paganism and
already observe Christian law. But we have no teachers who can in our
own language teach us the true Christian faith." The plea was sincere,
but Lützow judges it carried an equally real political purpose -
Rostislav and his uncle wanted a Moravian Church free of the Frankish
hierarchy, since the German priests already active in Moravia served
their own nation's interests as much as their faith's. Michael chose
two brothers from Thessalonica, Constantine and Methodius, native
speakers of a Slavic dialect, and sent them to Moravia the following
year.

An alphabet and a liturgy
Constantine arrived with a Bible he had already translated into
Slavic, written in a new alphabet of his own invention that would
later take his monastic name, Cyril, as its own - the first time a
Slavic language had been rendered in writing, and the point at which
it took its place beside Latin and Greek as a language fit for
worship. Churches multiplied and congregations came eagerly to
services conducted in a tongue they could actually understand, and the
brothers' reputation spread beyond Moravia's own borders into
neighbouring Pannonia. German clergy, and especially the Archbishop of
Salzburg whose own diocese the mission encroached on, denounced the
brothers to Rome as heretics, made easier by their Eastern origins and
their past association with the Byzantine Patriarch Photius - though
both brothers had in fact sided consistently with Rome throughout.
Constantine died in a Roman monastery in 869, but Methodius continued
the work, eventually securing from the Pope himself the title
Archbishop of Moravia and Pannonia and formal recognition of the new
script.

Betrayal repaid with betrayal
The religious contest ran alongside a political one that never really
paused. German armies attacked Rostislav's domains again in 864 and
868, without lasting success, and the resulting truce did nothing to
secure Rostislav's own position: his nephew Svatopluk, who governed
the district of Neutra under his uncle's authority, allied himself
with the Germans instead, captured Rostislav, and handed him over to
the Frankish prince Carlomann in 870. Carlomann's forces then occupied
the whole of Moravia, imprisoned Methodius and delivered him to hostile
German bishops, and - mistrusting the loyalty of the man who had just
delivered them their victory - arrested Svatopluk as well when a
Moravian revolt broke out shortly after. Svatopluk would answer that
betrayal in kind.
Uncontested lord of Moravia
peakDrafted from Lützow, Bohemia: An Historical Sketch (1920)
Appointed by the Germans to lead the army sent to crush the Moravian
revolt he had himself, in effect, provoked, Svatopluk deserted his
captors instead, put himself at the head of his own countrymen, and
destroyed the German force in a battle that killed both of the
Austrian margraves commanding it. The victory, in 871, left him
uncontested lord of Moravia - a position he moved quickly to secure
through an alliance with the Bohemian prince Bořivoj, sealed by a
marriage to Bořivoj's own sister, and through renewed war against the
Germans who were certain to come again. When Svatopluk carried that
war directly into Germany the following year, attacking Carlomann on
his own ground, Carlomann's father King Louis judged it wiser to
negotiate, and the resulting Treaty of Forcheim in 874 secured
Svatopluk's own conquests in northern Hungary, even if nominally still
under German supremacy.
The empire at its widest
Peace with Germany let Methodius return from captivity, and one of his
first acts was very likely the baptism of Bořivoj, the Bohemian prince
whose own wife Ludmila was received into the Church alongside him -
Christianity's decisive entry into Bohemia's own ruling house. Svatopluk
himself used the years of relative peace to expand in every direction,
becoming, in the source's own words, "the chief of a mighty Slavonic
empire" whose exact borders no one can now specify with confidence:
Kraków and the surrounding part of Poland, Silesia, a swath of
northern Germany reaching as far as Magdeburg, and a large part of
northern Bohemia had all, by one account, acknowledged his supremacy.
After Bořivoj's own death Svatopluk went further still, reducing
Bořivoj's sons Spytihněv and Vratislav to local chieftains under his
own authority and ruling Bohemia directly himself - temporarily
displacing the Přemyslid dynasty from the throne of the country it
would otherwise hold without interruption.

One more German war
Peace with Germany did not last through the reign. Svatopluk fought a
major war against King Arnulf, an illegitimate son of Carlomann,
beginning in 890, and two years later Arnulf brought in an unfamiliar
ally to help him: the Magyars, a people recently arrived in Europe and
at that time still settled somewhere near the lands the sources call
Moldavia. Svatopluk held off these combined attacks for the rest of
his reign, and the empire he had built reached, by his own death, the
furthest extent it would ever hold.
The quarrel that let the Magyars in
endDrafted from Lützow, Bohemia: An Historical Sketch (1920)
"The greatness of the Moravian Empire ended with his death," Lützow
writes of Svatopluk, who died in 894 leaving two sons, Mojmir and
Svatopluk, whose quarrel over the inheritance did more damage than any
outside enemy had managed in decades. The Bohemian prince Spytihněv
saw his opening in that intestine struggle and used it to shake off
Moravian overlordship entirely, restoring the Přemyslid dynasty's own
independent rule over the whole of Bohemia - the first and largest
piece of Svatopluk's empire to fall away, and one that would never
return to Moravian hands. Seeking his own protection against a Moravia
he had just broken from, Spytihněv turned to the same German power his
predecessors had fought for two generations, appearing with his
brother Vratislav at King Arnulf's own court at Regensburg to submit
to German and ecclesiastical supremacy in exchange for support - a
reversal that also brought Bohemia formally under the Latin liturgy,
though the Slavonic rite Cyril and Methodius had planted continued
alongside it for years after.
Pressburg
While Germans and Slavs wore each other down in their own recurring
wars, the Magyars - the very people Arnulf had once called in against
Svatopluk - grew steadily stronger on ground both powers had largely
ignored. Germans and Slavs eventually made common cause against this
shared threat, but their combined army was routed at the Battle of
Pressburg, traditionally dated to 907 though the source stresses that
"the exact date cannot be ascertained in the complete absence of
contemporary evidence." In the aftermath the Magyars overran Moravia
outright and held it for more than half a century afterward; only a
small western district survived under Bohemian rule. Lützow, quoting
the Czech historian Palacký, calls the Magyar conquest simply "the
greatest misfortune that has befallen the Slavonic world during
thousands of years" - the empire Rostislav had built to escape German
supremacy, and Svatopluk had carried to Kraków and Magdeburg, ended not
by the Germans at all, but by a people neither ruler had ever
seriously had to reckon with until it was already too late.

Svatopluk of Moravia had reduced Bohemia to a subject duchy under his own direct rule; his death in 894 set his sons quarrelling, and the Bohemian prince Spytihněv used the opening to throw off Moravian overlordship and restore the Přemyslid dynasty's own independent rule over the whole of Bohemia.
A joint German-Slav army raised to meet the Magyar advance broke at Pressburg, and the Magyars overran Moravia in the campaign that followed, holding it for more than half a century - the conquest the Kingdom of Hungary's own record traces its beginning to.
