Why did king Philip II of Macedonia take an interest in coquering Greece?

King Philip II of Macedonia sought to conquer Greece to unify the fragmented Greek city-states under his rule and establish Macedonian dominance in the region. He aimed to create a powerful coalition that could defend against external threats, particularly from Persia. Additionally, Philip's ambition was fueled by a desire for military glory and the potential to spread Hellenistic culture, which would later influence the broader Mediterranean world. His conquest also provided access to the wealth and resources of Greece, further strengthening Macedonia's position.
