Persia

Persia was the largest empire known to the world back then and was undefeatable. The Persia Empire was 10.7 million square kilometers. One of the reasons why Alexander was so great because he concurred and defeated Persia. No other ruler could concur Persia because of its massive size and army, but when Alexander was in charge, he demolished the Persian Empire. Persia never had a strategic army, but they had massive amounts of people in it. Alexander was a smart man but he had on 35 thousand men. he thought he had no chance. Alexander traveled to Persia by ships. The Persian Empire ignored them. Little did the Persians know that they were surrounded by Macedonians. Persia was ambushed and Persia was then defeated. Alexander got in control.
