Alexander the great was born around July 20, 356 B.C., in Pella.
Alexander's father, Philip the II became king of Macedonia and made his weapons more advanced by extending them to 18 feet and began winning wars was tad bit easier.
Philip the II attended his daughters wedding and one of his body guards killed him.
20 year old Alexander was left to be in charge of an entire kingdom of Macedonian Greece.
Most of the kingdom did not like Alexander because of his young age and fought over the throne but not many of them knew how smart he was until he started fulfilling his fathers by concurring Egypt, Greece and Persia.
Your not even smart!
Your not good enough!
Let me be the king!
Your to young!
Later he began concurring city states, villages, and other kings. He took over by force if they did not want to listen and took over by politeness if they surrendered and listened. He even spread the religion about Greek gods and saying everyone is equal.
