(356-323 B.C.) Alexander the Great was born to his parents, King Phillip II and Queen Olympia. He was tutored by Aristotle and was in charge of the Companion Cavalry at the age of 18.
Alexander assisted Phillip into defeating the Theban and Athenian armies at Chaeronea. After his father's death, Alexander gathered the support of the Macedonian Army. Soon he eliminated his army to be king and leader of Corinthian League.
Alexander continued on to overcome Persian Empire and all of Asia Minor, present day, turkey, Syria, and Palestine. Though Phillip only wanted to liberate these cities.
(334 B.C.E.) Alexander won the battle by sending in 34,000 men through the Asia Minor. His army won very single battle.
Alexander the great used a very effective military formation in ancient warfare called the Greek Phalanx. The phalanx formation was a close-rank,dense grouping of warriors armed with long spears and interlocking shields. Alexander combined this with cavalry on horseback in the rear.
With these tactics, Alexander was able attack the cities by the Mediterranean Sea and destroy Persia's Navy in Egypt. Because of this, Persia was not able to attack Greece due to Alexander's army. Once the Coastal was calmer, Alexander goes east and takes over Mesopotamia; though the Persian King ended up fleeing.
Alexander arrives in Persia in hoping to find Darius III ( The Persian leader) but instead he finds Darius killed by his officers.
Alexander marries a Persian woman named Roxana, as he also encouraged his officers to pro-generate or commingle with the Persians.
(323 B.C.E.) Alexander the Great passed away. Because of this, there was no longer a unified leader. They eventually split into four: Ptolemies in Egypt; Seleucid in Western Asia; Antigonids in Macedonia; Pergamum.
