How big was the Mongol Empire? In this video, we've mapped out a timeline of the Mongol conquests, from Genghis Khan to Kublai Khan and beyond.

You'll find out how the Mongol Empire grew from a collection of nomadic tribes on the Central Asian steppe, to the largest land empire in history. Charting the Mongols territorial expansion through the conquests of the Chinese Jin Dynasty to the Khwarazmian Empire in Persia, we'll show just how close the Mongols eventually came to conquering Medieval Europe.

Our Mongol Empire map shows how Genghis and his successors extended their rule over 20% of the world's land mass, and how the empire eventually fractured and broke apart.

Charting History is a brand new series for the History Hit YouTube channel, where we chart the rise and fall of history’s most successful empires. By unrolling the map, we’ll give you the big picture of events, plotting the course of imperial expansion, and collapse, as it really happened.
