Final answer:
Philip of Macedon conquered every major city-state in Greece except Sparta.
Step-by-step explanation:
Philip of Macedon conquered every major city-state in Greece except Sparta. He first defeated the allied armies of Athens and Thebes at the Battle of Chaeronea in 338 BCE. After that victory, he sought to unite the Greek city-states under his leadership and organized them for war against the Persian Empire.
The height of Hellenistic influence was evident in the establishment of cities like Alexandria, which became one of the world's largest and most culturally vibrant cities of the period. In 330 BCE, the Greeks even burnt Persepolis to the ground. Through these actions and the establishment of a common Hellenistic culture, Alexander drastically changed the landscape of the ancient world.
