The Battle of Plataea took place in 479 BCE during the Greco-Persian Wars. It was a decisive confrontation between the Greek city-states, led by Sparta and Athens, and the invading forces of the Persian Empire under General Mardonius. The battle occurred near the town of Plataea in Boeotia, Greece, and marked the end of the Persian invasion. The Greek forces, numbering around 38,000, successfully outmaneuvered and defeated the larger Persian army, which had approximately 100,000 troops. This victory solidified Greek independence and marked a turning point in the conflict, leading to the eventual decline of Persian influence in Greece.
