The Mongol Empire existed in the 13th and 14th centuries and was the largest contiguous empire in history. At its height it stretched from the Baltic Sea to the Sea of Japan, and from the frozen shores of Russland to the jungles of south-east Asia.
The Mongol Empire emerged from the unification of many Mongol and Turkic tribes under the leadership of Genghis Khan. Under the rule of he and his successors the empire grew rapidly, sending raids and invasions in all directions. By connecting east and west it allowed the dissemination and exchange of trade, technologies, scholarship and ideologies all across Eurasia.
