The Mongols resumed their assault on the lands of Rus in 1239, when they conquered Pereiaslavl (March) and Chernigov (October). A year later, after conducting additional campaigns in the steppe and the Caucasus, they laid siege to Kiev. The date of its fall—December 1240—marks the collapse of Kievan Rus. The Mongols continued their advance westward, subduing Galicia and Volhynia and pressing into Poland and Hungary. They halted their advance only in September 1242, when their leader Batu was recalled to Mongolia for the selection of a new great khan.
The Mongol campaigns devastated the lands of Kievan Rus. Among its major towns, Riazan, Vladimir, and Suzdal in the north-east, and Pereiaslavl, Chernigov, and Kiev in the southwest had been severely damaged. The ruling élite was also decimated. At the Battle of Sit alone, Prince Iurii Vsevolodich, three sons, and two nephews had all been killed. The invaders also ravaged the villages and fields in their path; peasants who were not slain or enslaved fled to safer locales. Where the Mongols passed, farming, trade, and handicrafts ceased. The Mongol invasion shattered the economic vitality and cultural vibrancy characteristic of Kievan Rus.
The Mongol invasion, however, did not disturb all the norms and traditions of the Kievan Rus. The devastation was neither ubiquitous nor total. In the north-east some towns, such as Rostov, Tver, and Iaroslavl, had not been touched. Although initially strained by the influx of refugees, these communities ultimately benefited economically from the labour and skills brought by their new residents. Novgorod, which similarly escaped the Mongol onslaught, continued to engage in commercial exchanges with its Baltic trading partners and import vital goods, including silver, to the Rus lands.
Lines of authority also remained unbroken: the metropolitan of Kiev and all Rus was still the leader of the Orthodox community, and the Riurikid dynasty remained the ruling house of Rus. While the Mongols pursued their westward campaign, the Riurikid princes were left to restore order, organize recovery efforts, and attempt to avert further invasion and destruction. They followed dynastic custom: the senior surviving prince of the eldest generation assumed the highest position in the northeast. When Prince Iurii Vsevolodich of Vladimir was killed at the Battle of Sit, his brother Iaroslav succeeded to his throne; their younger brothers, sons, and nephews assumed the thrones of other principalities—Suzdal, Starodub, Rostov, and Novgorod—in accordance with the dynastic rules of succession. In the southwestern principalities the princes of Volhynia and Chernigov similarly resumed their former seats.
The distribution of lands and resources among the remaining princes facilitated effective defensive measures against other foes. As early as July 1240 Prince Alexander, son of Prince Iaroslav Vsevolodich, earned the epithet ‘Nevsky’ by defeating the Swedes in a battle on the Neva river, thereby repulsing their attempt to seize control over Novgorod’s routes to the Gulf of Finland and the Baltic Sea. In another battle at Lake Peipus in 1242, he halted an eastward drive of the Teutonic Knights, who had been threatening the frontiers of Novgorod and Pskov.
When Batu returned to the steppe, he organized his realm as the Kipchak khanate or Desht-i-Kipchak, but commonly called the Golden Horde. It encompassed not only the Rus principalities but the steppe lands, extending from the Danube river in the west through the northern Caucasus and across the Volga river to the Sea of Aral. Its capital was Sarai, built on the lower Volga river. The Golden Horde constituted one component of the much larger Mongol Empire, which, at its peak, spanned an area stretching from Rus, Persia, and Iraq in the west to China and the Pacific Ocean in the east. The khans of the Golden Horde were subordinate to the great khan of the Mongol Empire (at least until the end of the thirteenth century), and their policies were shaped by imperial politics and their interactions with other components of the empire.
These factors influenced the nature of the khans’ relationships with the Riurikid princes. The khans assumed the right to confirm the Riurikid princes’ right to rule; to obtain a patent of authority
