Alexander the Great was born in 356. B.C, in Pella, which was once Macedonia’s capital. He was the son of Phillip II, whom at the time was King of Macedonia. King Phillip the second was assassinated in 336 B.C, when Alexander was forced to take over the crown. After stabilizing his role at home, he began strategizing his first attack.
First he attacked Thessaly to restore Macedonian rule there, and then in 335 B.C. he defeated the Thracians, up through the Danube River. Upon his return, he defeated and crushed the Illyrians, but rushed back afterwards to Thebes, which was in revolt. Thebes was destroyed by Alexander, sparing only temples and the house of Pindar, a well known Greek poet of the 5th Century B.C. Many more Greek states then turned to Alexander 's control.
Alexander declared war on Persia in 334 B.C., defeating a Persian army near the city of Troy. This resulted in the submission of all states in Asia Minor to him. Alexander then traveled south, where he defeated King Darius III, whom was the leader of the main Persian army. This battle occurred in 333 B.C. at Issus of Northeastern Syria. His next conquest occurred in Tyre in 332 B.C. Then he began his travels towards the Eastern Mediterranean. First he captured Gaza, and then traveled into capture Egypt. This gave him control over the entire eastern Mediterranean coastline, where he would establish the City of Alexandria, located at the mouth of the Nile River. The city of Alexandria would later become the scientific, literary, and commercial center of the Greek world.
After all his work in the eastern Mediterranean, he moved his forces to Babylon. Again, he defended Darius, now in 331 B.C., forcing Babylon to surrender. The following conquest after Babylon
