9.1 Philip II and the expansion of Macedonian power

Philip II transformed Macedonia from a weak kingdom into a dominant power in ancient Greece. His military reforms, including the sarissa and phalanx formation, revolutionized warfare and enabled rapid expansion. These innovations laid the foundation for Macedonian hegemony.

Philip's diplomatic skills and strategic conquests allowed him to exploit Greek disunity and establish control over the region. The Battle of Chaeronea in 338 BCE marked the end of Greek city-state independence and set the stage for Alexander's future conquests.
