Battle of the Eurymedon
The Battle of the Eurymedon was a double battle, taking place both on water and land, between the Delian League of Athens and her Allies, and the Persian Empire of Xerxes I. It took place in either 469 or 466 BCE, in the vicinity of the mouth of the Eurymedon River (now the Köprüçay) in Pamphylia, Asia Minor. It forms part of the Wars of the Delian League, itself part of the larger Greco-Persian Wars. The Delian League had been formed between Athens and many of the city-states of the Aegean to continue the war with Persia, which had begun with the first and second Persian invasions of Greece (492–490 and 480–479 BCE, respectively). In the aftermath of the Battles of Plataea and Mycale, which had ended the second invasion, the Greek Allies had taken the offensive, besieging the cities of Sestos and Byzantium.
