The Mongolian Empire

Among the countries that were part of this infamous colonizer were Iran, Iraq, and Pakistan, to name a few. In addition, when the topic is Mongolian Empire, one name always pops up, Genghis Khan. He is often referred to as one of the greatest conquerors in the history of the planet. During his reign, his leadership was responsible for wiping out around 40 million people on the planet, about 10% of the existing population.

When Kublai Khan passed on in 1294, however, the empire fragmented and slowly declined. By the 14th century, it was only a remnant of what it was before. While credit still goes to the Khans for leading successful campaigns, Alauddin’s army was the one who successfully thwarted further expansion.
