He continued his father Philip's plan to take over the Persian Empire.
Only the Greek states of the Hellenic League (also called the League of Corinth by historians) which was a federation of most of the Greek states created by Alexander's father, Philip II of Macedon, and were vassals of Macedon, and the Kingdom of Epirus (in western Greece), an ally, had never been part of the Persian Empire. Even Alexander's own kingdom of Macedon, had been part of the Persian Empire. It had been a vassal state of the Persians for nine years (512-493 B.C.) and was conquered by the Persians in 492 B.C. and remained a fully subordinated part of the Persian Empire for thirteen years. The Thracian tribes Alexander's father, Philip II, had conquered had also been part of the Persian Empire
He had immense vanity and ambition, like his father Philip II of Macedonia. After Philip was assassinated on the eve of his departure for Asia to take on the Persian Empire, Alexander took over and carried out his father's project successfully.
Having subdued his opponents in mainland Greece and elected Hegemon of Greece, Phillip II of Macedon wanted to stop the Persian interference in Greek affairs and exact payback for the Persian invasions in the 5th Century BCE (and incidentally of course gain an empire). He was assassinated before he set out, and his son Alexander carried out his father's plan.
King Xerxes tried to carry on his father Darius I's attempt to establish an ethnic frontier by subjugating mainland Greece, as the mainland Greek states were fomenting rebellion in the Greek states in Asia which were under Persian control. He lost, and Athens established an anti-Persian league which dominated the eastern Mediterranean. Although the internal fighting in the Greek world subsequently eroded the strength of the Greek states, and Persian gold was able to buy influence in them, the rise of Macedonia, and Philip II's and then Alexander's control of Greece tipped the balance of power against Persia. Alexander took the empire's Mediterranean coastline and so removed the Persian fleet, and as on land Persia's military forces were unable to match the power of Macedonian-Greek forces, he was able to defeat them in three major battles, and so take over the Persian Empire.
