The Persian Wars

499 – 449 BC · four phases · 50 years

Not one war but a series of them: a revolt in Ionia, two Persian invasions of Greece, and thirty years of Greek counterattacks. Thermopylae, Marathon and Salamis all belong to this story, but to different chapters of it.

The Persian perspective

How did Persia see these wars?

Almost everything we know comes from Greek writers, above all Herodotus. No Persian account of the wars survives. For Darius and Xerxes, Greece was a small frontier on the western edge of an empire that reached from Egypt to India: a matter of punishing Athens and Eretria for helping the Ionian revolt and burning Sardis.
