Step-by-step explanation:
Genghis Khan was the Mongolian warrior-ruler who consolidated tribes into a unified Mongolia and then extended his empire across Asia to the Adriatic Sea. He ruled the Mongol Empire for twenty-one years, establishing a law code and creating a sophisticated war machine capable of surprise attacks and deadly sieges. The Mongols created the largest contiguous empire in the thirteenth and fourteenth centuries, controlling an area stretching from central Europe to the Pacific Ocean.
During their conquests, the Mongols connected parts of the world that had never been connected before, facilitating trade and travel along the caravan routes of Central Asia. However, they made no technological breakthroughs, founded no religions, and didn't contribute much in terms of culture or civilization.
