Plataea was an ancient Greek city located in Boeotia, near the foot of Mount Cithaeron. It played a significant role in the Greco-Persian Wars, particularly during the Battle of Plataea in 479 BCE, where a coalition of Greek city-states defeated the Persian army. This victory marked a turning point in the struggle against Persian expansion in Greece. The city was also known for its strategic location and fertile land, which contributed to its prosperity. After the wars, Plataea became a member of the Delian League, an alliance of Greek city-states led by Athens. However, it later faced conflicts with Thebes, leading to its eventual decline.
