How big was the Mongol Empire

The Mongol Empire, under the reign of Genghis Khan (1162–1227 C.E.; also spelled Chingis Khan) and his son Ögedi Khan (1186–1241), became one of the greatest contiguous empires in world history. It would eventually stretch from what is now modern-day Korea and China in the east to Poland in the west, and to Vietnam and Oman in the south.
