In which year did the Battle of Plataea occur?

The Battle of Plataea occurred in 479 BC and is significant as it was one of the final battles of the Greco-Persian Wars. This decisive engagement saw the Greek city-states, united against the invading Persian forces, achieving a critical victory that helped to secure their independence from Persian control. The battle is particularly noteworthy because it demonstrated the effective collaboration and strategic planning among the Greek forces, primarily the Spartans and Athenians.

In the context of the other years provided, 405 BC refers to a later period in Greco-Roman warfare, specifically the time of the Peloponnesian War, while both 52 BC and 48 BC are associated with the Roman civil wars. These dates fall outside the timeframe of the Greco-Persian Wars and are not relevant to the events surrounding the Battle of Plataea. Therefore, the choice of 479 BC correctly identifies the year this important historical battle took place.
