Creation of the Mongol empire

It is probable that Turks were incorporated in the nascent Mongol empire. In a series of tribal wars that led to the defeat of the Merkits and the Naimans, his most dangerous rivals, Genghis gained sufficient strength to assume, in 1206, the title of khan. Acting in the tradition of previous nomad empires of the region, Genghis directed his aggressive policies primarily against China, then ruled in the north by the Jin dynasty. His western campaigns were set in motion quite accidentally by a senseless attack on Mongol forces by the fugitive Naiman prince Küchlüg, and they maintained their momentum through the pursuit of ʿAlāʾ al-Dīn Muḥammad of Khwārezm, who in 1218 ordered the execution of Mongol envoys seeking to establish trade relations.

As a result, many of the flourishing cities of Khwārezm, Khorāsān, and Afghanistan were destroyed, and, by 1223, Mongol armies had crossed the Caucasus. Although an important Russo-Kipchak force was defeated on May 31, 1223, at the battle of the Kalka, the Mongols did not make a definite thrust into eastern Europe until the winter of 1236–37. The fall of Kiev in December 1240—with incalculable consequences for Russian history—was followed by a Mongol invasion of Hungary in 1241–42. Although victorious against the forces of King Béla IV, the Mongols evacuated Hungary and withdrew to southern and central Russia. Ruled by Batu (d. c. 1255), the Mongols of eastern Europe (the so-called Golden Horde) became a major factor in that region and exerted a decisive influence on the development of the Russian states.

Simultaneously with these western campaigns, Genghis’s successor Ögödei (ruled 1229–41) intensified Mongol pressure in China. Korea was occupied in 1231, and in 1234 the Jin dynasty succumbed to Mongol attacks. The establishment of the Yuan (Mongol) dynasty in China (1260–1368) was accomplished by the great khan Kublai (1260–94), a grandson of Genghis.
