#7 The Japanese Empire
While this empire may not have lasted as long as some of the others on this list, it was still extremely powerful. The empire lasted from 1868 to 1947, when U.S.-dropped atomic bombs lead to the surrender of the empire. The Japanese Empire was also amongst the largest maritime empires in history.
#6 The Mongol Empire
The Mongol Empire will perhaps go down as one of the most violent and dominant empires of all time. The empire is without a doubt best known for its leader, Genghis Khan. This empire existed during the 13th and 14 centuries, and under Khan, ruled much of Central Asia and China. The next empire was also known best because of its leader.
#5 The Nazi Empire
This was a very short reign but was without a doubt one of the deadliest in history. Nazi Germany refers to a period in the country’s history when it was ruled by Adolf Hitler (from 1933 to 1945). Hitler and his party had total control over German life and of course went on to incite the biggest and deadliest war of all time, World War II.
#4 The Spanish Empire
The Spanish Empire began with Christopher Columbus and his voyages West. Quickly, the empire founded colonies and territories all over the world. During their prime, this empire was extremely wealthy and thus, held a lot of power. They were also masters at navigation, which is how they were able to spread so far so quickly.
#3 The Russian Empire
This empire lasted from 1721 until 1917 and was among the biggest in history. In fact, in terms of land mass, it was third to only the British and the Mongol empire. At the end of this empire, it was estimated there were about 181 million people who called it home before it collapsed.
