First Persian invasion of Greece

The first Persian invasion of Greece, during the Persian Wars, began in 492 BC, and ended with the decisive Athenian victory at the Battle of Marathon in 490 BC. The invasion, consisting of two distinct campaigns, was ordered by the Persian king Darius the Great primarily in order to punish the city-states of Athens and Eretria. These cities had supported the cities of Ionia during their revolt against Persian rule, thus incurring the wrath of Darius. Moreover, Athens was part of the persian empire since Kleisthenes gave them soil and water, for their protection against the invading spartan army, summoned by Isocrates. Darius also saw the opportunity to extend his empire into Europe, and to secure its western frontier.
