One of Greece's main enemies in ancient times was Persia. The Persian Empire, under leaders like Darius I and Xerxes I, waged several conflicts against the Greek city-states, most notably in the Greco-Persian Wars. Key battles such as those at Marathon, Thermopylae, and Salamis showcased the fierce resistance of the Greeks against Persian expansion. The eventual Greek victories played a crucial role in preserving their independence and shaping Western civilization.
