Genghis Khan started the Mongol Empire
The Mongol Empire, which Genghis Khan (Mongolian: Chinggis Khaan) is credited with creating, was the largest empire in recorded history at the time. He ruled over a large portion of what is now modern China. On an incredible scale, he and his army killed, destroyed, and reformed. Although he is renowned as the greatest conqueror in history, little is actually known about him.
Other tribes oppressed the Qiyan tribe when it was in decline. Genghis Khan was captured during a raid by the Tayichi'ud tribe, but he managed to escape. Genghis Khan recognized that in order to fend off persecution, he had to look for protection from a stronger force. He then turned to Toghrul, the clan chief of the Keraites and a close friend of his father's. He then started to gain strength and loyal supporters.
The Mongol tribes attacked because they could not stand Genghis Khan's rising dominance. He was able to unite or subjugate a number of large nomadic tribes and minor countries that fell under his dominion through the defeat of his adversaries, the formation of alliances, and winning the devotion of others. Finally, he succeeded to unify the Mongols. At a council of Mongol emperors in 1206, he was referred to as Genghis Khan and recognized as a "Khan" ('ruler' or'military leader').
