Mongol Invasion of Kievan Rus (1237-1240) and the Fall of Kyiv

The Mongol invasion of Kievan Rus was a series of campaigns from 1237 to 1240 in which the armies of Batu Khan conquered the principalities of the Rus, the medieval East Slavic state centred on Kyiv. City after city fell, from Ryazan and Vladimir in the north-east to Chernigov and finally Kyiv itself on 6 December 1240. The conquest placed the Rus lands under the overlordship of the Golden Horde for more than two centuries and shaped the later histories of Russia, Ukraine and Belarus.

Background: a divided Rus

By the 13th century Kievan Rus was no longer a single state. Since the time of Yaroslav the Wise in the 11th century it had split into a dozen or more principalities, ruled by branches of the Rurikid dynasty that fought each other for Kyiv and other prizes. Powerful centres included Vladimir-Suzdal in the north-east, Novgorod in the north, Chernigov, Galicia-Volhynia in the south-west, and Kyiv, still the senior city and the seat of the Church’s metropolitan.

The Mongols had already appeared once. In 1223 a reconnaissance force under the generals Jebe and Subutai defeated an alliance of Rus princes and Cumans at the Kalka River, then vanished back into the steppe. The Rus did not treat it as a warning.

The Mongol Empire founded by Genghis Khan continued to expand after his death in 1227. In 1235 a great assembly, or kurultai, under his son Ögedei decided on a major western campaign. Its commander was Batu, son of Genghis Khan’s eldest son Jochi, whose share of the empire lay in the west. Subutai, the victor of the Kalka, served as his chief general. Princes from every branch of the family joined, including Möngke and Güyük.

The northern campaign, 1237-1238

In 1236 the Mongols destroyed Volga Bulgaria, a trading state on the middle Volga. Late in 1237 they moved against Ryazan, the easternmost Rus principality. Prince Yuri of Ryazan asked for help, but Grand Prince Yuri II of Vladimir did not send it. Ryazan was besieged from about 16 December and stormed on 21 December 1237. The chronicles describe the slaughter of its people.

The Mongols then advanced in winter, using frozen rivers as highways. Kolomna and Moscow, then a minor town, were taken in January 1238. Vladimir, the capital of the grand principality, was besieged from 3 February and fell on 7 February. Members of the grand prince’s family died when the cathedral where they had taken refuge was set on fire. Suzdal, Rostov, Yaroslavl, Tver and other towns were captured during February.

Yuri II had gathered an army on the Sit River, north of the Volga. On 4 March 1238 the Mongols surprised and destroyed it, and Yuri was killed. The next day, after a two-week siege, Torzhok fell. The road to Novgorod seemed open, but about 100 versts (roughly 100 km) short of the city the Mongols turned south, probably because of the spring thaw, which turned the land into marsh. Novgorod was spared. It would soon accept Mongol overlordship without a siege, and its prince, Alexander Nevsky, became one of the khans’ most reliable vassals while fighting western enemies such as the Teutonic Knights.

On the way south the small town of Kozelsk held out for about seven weeks. The Mongols reportedly called it the “evil city” and killed all its inhabitants when it fell.

Pause and the southern campaign, 1239-1240

The Mongols spent 1238 and much of 1239 on the steppe, fighting the Cumans, Alans and Circassians. Thousands of Cumans under Khan Köten fled west into Hungary. In 1239 Mongol forces took Pereyaslavl (3 March) and Chernigov (18 October), and attacked Mordovian and Rus towns in the east.

Kyiv’s princes had been quarrelling over the city. Around 1239 Möngke reached the Dnieper and is said to have admired the city and called on it to surrender, without success. Prince Mikhail of Chernigov, who then held Kyiv, fled to Hungary. By 1240 the city belonged to Prince Daniel of Galicia, who left it in the hands of his military commander, the voivode Dmytro (Dmitri).

The fall of Kyiv, 1240

In late 1240 Batu’s main army surrounded Kyiv. The Hypatian Chronicle, the main Rus source for the south, says that the noise of carts, camels and horses was so loud that people inside could not hear each other speak. The Mongols battered the walls near the Polish (Lyadsky) Gate with siege engines and broke in. The defenders made a last stand around the Church of the Tithes, Kyiv’s oldest stone church, built after the Christianization of Rus in 988. It collapsed under the weight of the people who had climbed onto it. The city fell on 6 December 1240.

Dmytro was wounded and captured, but Batu spared him for his courage. Much of the city was burned, and its population was killed, enslaved or scattered. In 1246 the papal envoy John of Plano Carpini, travelling to the Mongol court, wrote that Kyiv had been reduced to about 200 houses and that countless skulls and bones of the dead lay on the fields.

Archaeologists have found evidence of the destruction across Kyiv and in other towns, including burned houses, hidden hoards of treasure never recovered, and mass graves.

Galicia-Volhynia and the road west

From Kyiv the Mongols moved into Galicia-Volhynia, taking Volodymyr, Halych and other towns in the winter of 1240-1241. In spring 1241 they invaded Poland and Hungary, winning the Battle of Legnica on 9 April and the Battle of Mohi on 11 April. In 1242 Batu withdrew to the lower Volga after news of Ögedei’s death.

Key people

• Batu Khan (c. 1205-1255): grandson of Genghis Khan, commander of the western campaign and founder of the Golden Horde.
• Subutai: the veteran Mongol general who planned many of the campaign’s operations.
• Yuri II Vsevolodovich: Grand Prince of Vladimir, killed at the Sit River in 1238.
• Daniel of Galicia: Prince of Galicia-Volhynia, who held Kyiv in 1240 and later accepted Mongol overlordship.
• Dmytro: the voivode who led the defence of Kyiv.
• Mikhail of Chernigov: Prince of Chernigov and Kyiv, executed at Batu’s camp in 1246 and later venerated as a saint.

Consequences: the Golden Horde

Batu founded a state on the lower Volga, centred on his new capital of Sarai, known in Western and Russian tradition as the Golden Horde. The Rus princes kept their thrones but now needed a patent (yarlyk) from the khan to rule. In 1243 Grand Prince Yaroslav II of Vladimir travelled to Batu’s camp and was confirmed as senior prince, setting the pattern for the following centuries.

The Mongols carried out censuses in the 1250s and imposed regular tribute, often collected by the princes themselves. Revolts were punished with new raids. Many craftsmen were deported, and stone building almost stopped for decades in the north-east. Trade routes shifted, and the old centre of Kyiv lost its leading role. In 1299 the metropolitan of the Church moved his residence from Kyiv to Vladimir, and later to Moscow, a symbolic sign of how far the balance of power had shifted to the north-east.

Legacy

Mongol overlordship over the north-eastern principalities is traditionally said to have ended with the Great Stand on the Ugra River in 1480, under Ivan III of Moscow. Russian historians later called this period the “Tatar yoke”. Its long-term effects are still debated: older historians stressed destruction and isolation from Europe, while others point out that Moscow rose to power partly as the khans’ favoured tax collector and borrowed Mongol administrative practices.

In the south-west, Galicia-Volhynia survived as a separate state for another century before being divided between Poland and Lithuania. Kyiv itself gradually recovered and later came under Lithuanian rule. The different paths taken by the former Rus lands after 1240 are one of the roots of the separate histories of Russia, Ukraine and Belarus.

Why it matters

The Mongol conquest ended the age of Kievan Rus. It destroyed many of its cities, bound its princes to the khans for over two centuries, and set the eastern Slavic lands on separate paths that still shape the map of Eastern Europe.
