Kievan Rus'

A river taken from two countrymen

The Book of Annals, the medieval compilation that is the main narrative source for this period, tells a founding story that starts with an invitation rather than a conquest. Around 862, it says, the Slavic and Finnic peoples of the north had fallen into such disorder fighting among themselves that they sent across the sea for a Varangian chieftain named Riurik to come and rule them, and Riurik settled at Novgorod with his brothers. Whether a real Riurik stands behind the story, or whether it is a founding legend built around a genuine Varangian presence in the region, is disputed among historians; what happened next is better attested.

Two Varangians already held the prize

Riurik died leaving an infant son, and it was Oleg, ruling as regent, who made the decision that actually founded this Kyiv-based polity. Two other Varangians, Askold and Dir, had already made themselves masters of Kyiv, far to the south on the Dnieper, independently of Riurik's own authority. Around 878 Oleg moved south, took the city from them, and shifted the centre of the whole enterprise there - trading Novgorod's access to the Baltic for a capital on the river road that ran all the way to the Black Sea and Byzantium.

What the river was for

The whole point of the position was the water. Furs, honey, wax and slaves moved down the Dnieper toward Byzantine markets; silver and manufactured luxuries moved back up it. Oleg spent much of his reign extending control over the Slavic tribes along that route and drawing them into paying tribute to Kyiv rather than to the Khazar khaganate, whose own reach had previously extended into the same territory. A war against Magyar raiders passing through the region around 890 was, by the chronicle's own account, indecisive - a reminder that the new Kyiv-based polity was one power on a contested frontier rather than an unchallenged one.

An old man's death, and a house that would rule for centuries

Oleg died in 913, according to the chronicle tradition, and was succeeded by Riurik's own son. Every prince who would later hold any part of this loose federation, for the whole three and a half centuries down to the Mongol conquest, claimed descent from that same house - a single genealogical thread run through a political structure that would prove, in practice, to be anything but single.

A sister for an army

Vladimir did not become a Christian because a missionary convinced him. He became one because the Byzantine emperor Basil II was, in the winter of 987-88, in genuine danger of losing his throne to a rebel general who had seized most of Anatolia and was approaching Constantinople itself, and Basil needed an army Vladimir alone could supply on short notice.

What was actually being traded

Byzantine envoys reached Kyiv in January or February 988 to ask for six thousand Varangian troops. What they offered in return was extraordinary by the standards of Byzantine court protocol: the hand of Princess Anna, Basil's own sister, in marriage. Anna was "porphyrogenete" - born in the imperial palace to a reigning emperor - and a Byzantine court that had, within living memory, refused a similar request from the German emperor's own son had never given a woman of that rank to a foreign ruler. Vladimir accepted, and his one obligation in return was to be baptised.

The soldiers arrived. The bride did not, at first.

Vladimir kept his side of the bargain in full: six thousand Varangian troops reached Constantinople that summer, tipped the military balance against the rebellion, and helped destroy the rebel army the following spring. Vladimir was baptised, apparently in February 988, and took the Christian name Basil in honour of the emperor whose throne he had just saved.

Basil, once the danger had passed, found himself much less eager to actually send his own sister north. Vladimir's answer was to attack the Byzantine possessions in Crimea directly, applying exactly the kind of pressure that finally produced the marriage the treaty had promised - and with it, most historians believe, the beginnings of an organised Christian church answering to Kyiv rather than simply to Constantinople.

What arrived along with the treaty

Christianity came to Rus' bundled with an entire administrative and cultural apparatus: a written liturgy in Slavonic rather than Greek, an alphabet already adapted for Slavic speech by earlier missionaries to the Bulgarians, and a model of sacred kingship that let a prince who had just paid for his own bride with an army present his rule as divinely sanctioned rather than merely won by force. Vladimir's own reputation in later Rus' memory rests less on the transaction that produced his conversion than on what he did with the authority it gave him - but the transaction is what actually happened, negotiated in the same terms as any other alliance of the age.

A code and a continent of in-laws

Iaroslav did not come to Kyiv's throne peacefully. Vladimir's death in 1015 set off a war among his sons in which one brother, Sviatopolk, seized power first and was accused by later chroniclers of murdering several of his own siblings to secure it. Iaroslav, ruling from Novgorod, was the one brother who fought back, and it took the better part of a decade of intermittent civil war - with both sides hiring outside troops, Iaroslav's Varangians against Sviatopolk's Pecheneg allies - before he held Kyiv without a serious rival.

What he did with an uncontested throne

Once secure, Iaroslav governed for close to two decades in relative peace, and used it to give Rus' its first written body of law: the Russkaia Pravda. It set compensation payments for injury and death by precise rank and circumstance, regulated commercial disputes, and gave Rus' a legal code of its own generations before many of the polities that would later outlast it had anything comparable. His sons expanded it further after his death, adding provisions that reflect a more developed commercial economy than his own reign had known.

Constantinople's princesses, in reverse

The most striking measure of the kingdom's standing under Iaroslav is who wanted to marry into it. Where his father Vladimir had needed an army to win a single Byzantine bride, Iaroslav's own daughters were sought by ruling houses across Europe on ordinary diplomatic terms. Elizabeth married King Sweyn II of Denmark. Anna, in 1051, married Henry I of France and was crowned queen - the marriage arranged specifically because the French court, needing an heir after Henry's first wife died childless, concluded that the prince of Kyiv's own family was worth approaching. Widowed in 1060, Anna served as a power behind her young son Philip I's regency and signed at least one surviving document "Anna Regina" in Slavic characters, a queen of France still writing in the alphabet Rus' had taken from Bulgaria seventy years before.

What the marriages actually measured

None of this reflected Kyiv projecting power abroad in any military sense. It reflected the opposite: a kingdom secure and prosperous enough, under one uncontested ruler, that distant courts thought a marriage tie to it worth having on its own terms. That kind of reputation depends entirely on the stability that produces it, which is exactly what Iaroslav's own death would remove. The division of authority he arranged among his surviving sons was meant to preserve what he had built. It became, within a generation, the mechanism that undid it.

A ladder nobody would climb in order

Iaroslav's arrangement for his succession was, on its own terms, a reasonable answer to a real problem. Rather than name one son to inherit a single throne and leave the others to fight for scraps, he divided authority among his surviving sons collectively, on the principle that Kyiv and its lesser cities belonged to the whole princely house rather than to any one branch of it. The senior member of the family, by age within the generation, held Kyiv; the next senior held the next most important city; and when a prince died, everyone below him was supposed to move up a rung.

What made the ladder impossible to climb in order

The rule assumed a family willing to wait its turn and princes content to hold whatever rung their birth order gave them. Neither assumption held for long. A prince who died before reaching Kyiv left sons who believed they had been cut out of an inheritance their father would eventually have received, and those sons rarely accepted exclusion quietly. Within a couple of generations the "ladder" was less a working system than a standing justification both sides in any given war could invoke for their own claim, and Rus' politics from the mid-eleventh century on is a near-continuous record of princely coalitions fighting each other over whose reading of seniority was the correct one.

A capital taken and abandoned in the same campaign

The clearest sign of how far the old order had come apart happened in 1169, when Andrei, prince of the northeastern city of Suzdal, led an army against Kyiv itself over exactly this kind of succession dispute. His forces took "the mother of Russian cities" - the honorific by which Kyiv was still known - and sacked it without restraint. Then Andrei did something no earlier winner of Kyiv had done: he went home, ruling from his own northeastern capital rather than moving to occupy the throne he had just captured by force.

What the shrug meant

Kyiv kept its ceremonial primacy as the notionally senior seat of the whole princely house for another seven decades. It never again carried the political weight that title had once implied. Power in the Rus' lands had visibly begun shifting toward the northeast, toward Novgorod's own trading networks, and toward the southwestern principality of Galicia-Volhynia - three separate centres of gravity rather than one, each capable of fielding an army but none capable, any longer, of holding the others in a single working system. It was that fragmented federation, not the unified realm Iaroslav had once ruled, that the Mongols would find when they arrived.

What a federation could not do

By the time a Mongol army under Batu reached the Dnieper in the winter of 1240, Kyiv had not been the effective centre of Rus' power for seventy years. It kept a title. It did not keep an army large enough, or allies close enough, to matter against what was coming.

A federation, not a fortress

The Rus' principalities Batu's forces met were exactly what a century of succession wars had made them: separate courts at Kyiv, at Suzdal and Vladimir in the northeast, at Galicia and Volhynia in the southwest, and around Novgorod in the north, each with its own army and its own quarrels with the others, and none of them under any single command that could have organised a combined defence even if all of them had wanted one. Mongol columns had already broken Rus' forces once before, at the river Kalka in 1223, in a battle several princes had ridden to and several others had ignored.

December 1240

Kyiv itself, when Batu's army reached it, was governed in the name of an absent prince, Michael of Chernigov, by a boyar acting as his deputy. There was no reigning ruler in the city to lead its defence or to negotiate its surrender. The city fell and was destroyed. What had been, within living memory of some who died in it, "the mother of Russian cities" ceased to function as anyone's capital.

What ended, and what did not

No Rus' prince, in the aftermath, claimed to be founding something new. Every princely line that continued - in the northeast, in Novgorod, in the southwest - traced its own legitimacy back to the same house Riurik's tradition had begun, the same claim every contender in the preceding century's succession wars had already been making. What changed was that all of them now held their thrones by a khan's confirmation rather than by right of the house alone, a condition that would last two and a half centuries and that none of the princes who lived through 1240 had any way of knowing would eventually be undone by one of their own descendants, ruling from a city that had barely mattered while Kyiv still did.
