Step-by-step explanation:
The Mongol Empire rose to power in Asia by uniting several tribes in northern Asia. The founder of the empire, Chinggis Khan, was able to forge a unified empire between 1206 and 1227. The Mongol armies, consisting of highly disciplined cavalry, quickly overran vast territories, including China, Russia, and the Middle East. Their military success, combined with their efficient administration and encouragement of trade, allowed them to build the world's largest empire.
