The Mongol Empire Was the Largest Contiguous Land Empire in History

The Mongol Empire founded by Genghis Khan in 1206 became the largest contiguous land empire in world history. At its greatest extent in the late 13th century, it spanned roughly 9 million square miles or 23 million square kilometers of territory. This vast realm stretched from the Pacific Ocean in the east to the Danube River and the shores of the Persian Gulf in the west. The empire encompassed all of modern-day China, Central Asia, the Middle East, and large portions of Eastern Europe. To put this in perspective, the Mongol Empire was larger than the Roman Empire, the British Empire, and the Alexandrian Empire combined in terms of contiguous landmass. The sheer scale of the empire meant that it connected diverse civilizations and facilitated unprecedented cultural and economic exchange across Eurasia.
