The greatest confrontations involved the heirs of Grand Prince Vladimir Monomakh (1113–25). By the time of his death, his sons had become the exclusive heirs to the grand princely throne; first Mstislav (1125–32), then Iaropolk (1132–9) ruled as grand prince. An attempt by Iaropolk to arrange for his nephew (Mstislav’s son) to be his successor provoked objections from his younger brother, Iurii Dolgorukii, the prince of Rostov-Suzdal. The struggle persisted until 1154, when Iurii finally ascended to the Kievan throne and restored the traditional order of succession.
An even more destructive conflict commenced after the death in 1167 of Grand Prince Rostislav Mstislavich (who had appropriately succeeded his uncle Iurii). When a member of the next generation (Mstislav Iziaslavich, the prince of Volhynia) attempted to seize the throne, a coalition of princes formed to oppose him. Led by Iurii’s son Andrei Bogoliubskii, it represented the senior generation of eligible princes, but also included the sons of the late Grand Prince Rostislav and the princes of Chernigov. The conflict culminated in 1169, when Andrei’s sons led a campaign that resulted in the flight of Mstislav Iziaslavich and the sack of Kiev. Andrei’s brother Gleb, as prince of Pereiaslavl (traditionally the main seat of the house of Monomakh), became grand prince of Kiev.
Prince Andrei personified the growing tensions between the increasingly powerful principalities of Kievan Rus and their centre Kiev. As prince of Vladimir-Suzdal, he concentrated on the development of Vladimir and challenged the primacy of Kiev by building the Church of the Dormition in 1158 and his own Golden Gate. He also constructed his own palace complex of Bogoliubovo outside Vladimir, conducted campaigns against the Volga Bulgars, celebrated a victory over them in 1165 by building the Church of the Intercession nearby on the Nerl river, and extended his influence over Novgorod. Andrei used his power and resources, however, to defend the principle of generational seniority in the succession to Kiev. But his victory was short-lived: when Gleb died in 1171, Andrei’s coalition failed in its attempt to secure the throne for another of his brothers. The renewed struggle ended instead with a prince from the Chernigov line on the Kievan throne; his reign and the accompanying dynastic peace lasted until 1194.
By the turn of the century, eligibility for the Kievan throne was confined to three main lines: princes of Volhynia, Smolensk, and Chernigov. When the prince of Volhynia (representing the junior generation) claimed the throne, the rules of eligibility and succession were temporarily waived due to the sheer power that he was able to muster. Although the primacy of the senior generation was restored upon his death in 1205, new rivalries emerged. By the mid-1230s, princes of Chernigov and Smolensk were locked in a prolonged conflict over Kiev. But in this case the combatants were of the same generation and each was the son of a grand prince; dynastic traditions were offering little guidance for determining which prince had seniority.
The dynastic contests of the early thirteenth century had serious consequences. During the hostilities Kiev was sacked twice more, in 1203 and 1235. The strife revealed the divergence between the southern and western principalities (which were deeply enmeshed in the conflicts) and those of the north and east (which were indifferent). Intradynastic conflict, compounded by the lack of cohesion among the components of Kievan Rus, undermined the system of shared power that had previously ensured the integrity of the realm. Kievan Rus was thus left without effective defences when it had to face a new, overwhelming threat from the steppe—the Mongols.
The Rus Principalities under Mongol Domination
In 1237–40, the Mongols extended their empire, founded by Genghis Khan, over the lands of Rus. Their first victim was the north-eastern principality of Riazan. After besieging and sacking its capital, the Mongols next destroyed the fortified outpost of Moscow and then advanced northward towards the capital of the main principality in the north-east, Vladimir. By the time they arrived there in early February 1238, its prince, Iurii Vsevolodich, had left the city to gather an army; meeting little resistance, the invaders laid siege, stormed, and sacked Vladimir as well as the neighbouring town of Suzdal. When Prince Iurii belatedly brought up his army to face the Mongols, it suffered a crushing defeat in a battle on the Sit river (4 March 1238). The Mongols then proceeded westward towards Novgorod, but broke off their campaign to summer in the steppe. The following winter they subdued the Polovtsy and the peoples of the North Caucasus.
