How many square kilometers did the Mongol Empire cover at its peak, making it history's largest contiguous land empire?
Answer
24,000,000 square kilometers
That's about 16% of Earth's entire land surface, stretching from Korea to Hungary — all conquered within roughly 70 years, mostly on horseback. The Roman Empire at its height was around a fifth of that size.
