Alexander the Great created a huge empire not only by the standards of the time but even by today’s standards. This is why he is believed to be the greatest conqueror of all time. But if we take a look at actual facts, we will see that the Mongol Empire was actually the biggest in the world.

In the 12th-14th centuries, the Mongols owned all of Central Asia, China, the Middle East, Korea, and Eastern Europe all the way up to Austria. To put this in perspective: Alexander the Great only had ancient Egypt, a part of Persia, and a part of India. Also, right after the monumental Alexander the Great died, his empire ceased to exist whereas the Mongol Empire existed for a much longer time.
