Military of the Mongol Empire

During the Mongol invasions and conquests, which began under Genghis Khan in 1206–1207, the Mongol army conquered nearly all of continental Asia, including parts of the Middle East, and parts of Eastern Europe. The efforts of Mongol troops and their allies enabled the Mongol Empire to become the contemporarily largest polity in human history. Today, the former Mongol Empire remains the world's largest polity to have ever existed in terms of contiguous land area and the second-largest polity overall, behind only the British Empire.
