Genghis Kahn (Part VI)

Georgia, Crimea, Kievan Rus and Volga Bulgaria

After the defeat of the Khwarazmian Empire in 1220, Genghis Khan gathered his forces in Persia and Armenia to return to the Mongolian steppes. Under the suggestion of Subutai, the Mongol army was split into two forces. Genghis Khan led the main army on a raid through Afghanistan and northern India towards Mongolia, while another 20,000 (two tumen) contingent marched through the Caucasus and into Russia under generals Jebe and Subutai. They pushed deep into Armenia and Azerbaijan. The Mongols defeated the kingdom of Georgia, sacked the Genoese trade-fortress of Caffa in Crimea and overwintered near the Black Sea. Heading home, Subutai's forces attacked the allied forces of the Cuman–Kipchaks and the poorly coordinated 80,000 Kievan Rus' troops led by Mstislav the Bold of Halych and Mstislav III of Kiev who went out to stop the Mongols' actions in the area. Subutai sent emissaries to the Slavic princes calling for a separate peace, but the emissaries were executed. At the Battle of Kalka River in 1223, Subutai's forces defeated the larger Kievan force. They may have been defeated by the neighboring Volga Bulgars at the Battle of Samara Bend. There is no historical record except a short account by the Arab historian Ibn al-Athir, writing in Mosul some 1100 miles away from the event.  Various historical secondary sources – Morgan, Chambers, Grousset – state that the Mongols actually defeated the Bulgars, Chambers even going so far as to say that the Bulgars had made up stories to tell the (recently crushed) Russians that they had beaten the Mongols and driven them from their territory. The Russian princes then sued for peace. Subutai agreed but was in no mood to pardon the princes. As was customary in Mongol society for nobility, the Russian princes were given a bloodless death. Subutai had a large wooden platform constructed on which he ate his meals along with his other generals. Six Russian princes, including Mstislav III of Kiev, were put under this platform and crushed to death.

The Mongols learned from captives of the abundant green pastures beyond the Bulgar territory, allowing for the planning for conquest of Hungary and Europe. Genghis Khan recalled Subutai back to Mongolia soon afterwards, and Jebe died on the road back to Samarkand. The famous cavalry expedition led by Subutai and Jebe, in which they encircled the entire Caspian Sea defeating all armies in their path, remains unparalleled to this day, and word of the Mongol triumphs began to trickle to other nations, particularly Europe. These two campaigns are generally regarded as reconnaissance campaigns that tried to get the feel of the political and cultural elements of the regions. In 1225 both divisions returned to Mongolia. These invasions added Transoxiana and Persia to an already formidable empire while destroying any resistance along the way. Later under Genghis Khan's grandson Batu and the Golden Horde, the Mongols returned to conquer Volga Bulgaria and Kievan Rus' in 1237, concluding the campaign in 1240.

Western Xia and Jin Dynasty

The vassal emperor of the Tanguts (Western Xia) had earlier refused to take part in the Mongol war against the Khwarezmid Empire. Western Xia and the defeated Jin dynasty formed a coalition to resist the Mongols, counting on the campaign against the Khwarazmians to preclude the Mongols from responding effectively.

In 1226, immediately after returning from the west, Genghis Khan began a retaliatory attack on the Tanguts. His armies quickly took Heisui, Ganzhou, and Suzhou (not the Suzhou in Jiangsu province), and in the autumn he took Xiliang-fu. One of the Tangut generals challenged the Mongols to a battle near Helan Mountains but was defeated. In November, Genghis laid siege to the Tangut city Lingzhou and crossed the Yellow River, defeating the Tangut relief army. According to legend, it was here that Genghis Khan reportedly saw a line of five stars arranged in the sky and interpreted it as an omen of his victory.

In 1227, Genghis Khan's army attacked and destroyed the Tangut capital of Ning Hia and continued to advance, seizing Lintiao-fu, Xining province, Xindu-fu, and Deshun province in quick succession in the spring. At Deshun, the Tangut general Ma Jianlong put up a fierce resistance for several days and personally led charges against the invaders outside the city gate. Ma Jianlong later died from wounds received from arrows in battle. Genghis Khan, after conquering Deshun, went to Liupanshan (Qingshui County, Gansu Province) to escape the severe summer. The new Tangut emperor quickly surrendered to the Mongols, and the rest of the Tanguts officially surrendered soon after. Not happy with their betrayal and resistance, Genghis Khan ordered the entire imperial family to be executed, effectively ending the Tangut lineage.
