Final answer:
Philip II aimed to unite the Greek city-states to launch a campaign against the Persian Empire after his victory at the Battle of Chaeronea in 338 BCE. The goal was both to satisfy his troops' desire for loot and to assert Macedonian dominance over Greece by avenging previous Persian incursions.
Step-by-step explanation:
Philip II's Goal for a United Greece
After consolidating power with the decisive Macedonian victory at the Battle of Chaeronea in 338 BCE, Philip II declared that the goal for a united Greece would be to wage war against the Persian Empire. This initiative was both a response to his men's demand for further conquest and loot and an attempt to unify Greece with a common objective. Despite the Greeks' reluctance to accept Macedonian leadership and the occupation that followed their defeat, Philip exercised diplomacy and military strength to maintain control, using the cultural pretext of avenging past Persian invasions to foster a sense of unity and purpose among the Greek city-states.
Philip II of Macedon sought to expand his newly obtained territories and to utilize Greece's resources for a grand campaign, now recognized in history as shifting Greece towards the Hellenistic Era. His son, Alexander the Great, later realized his father's vision by defeating the Persian Empire and further stretching the boundaries of the Macedonian Empire.
