Frequently Asked Questions
5 questions
Greece's city-states remained politically fragmented and competed internally, weakening collective strength. Macedonia's Philip II and his son Alexander conquered Greek territories (338 BCE), and Rome systematically absorbed Greek lands after 146 BCE. Rome's centralized government and professional military proved superior to autonomous city-state militias. The Peloponnesian War (431-404 BCE) also exhausted Greek city-states, killing ~10% of Athens' population.
