Persia

Achaemenid Empire

In 499 BC, Athens supported a revolt in Miletus, resulting in the sacking of Sardis. This led to the Greco-Persian Wars, which lasted the first half of the 5th century BC. In the First Persian invasion of Greece, Persian general Mardonius re-subjugated Thrace and made Macedon a full part of Persia. Darius' successor Xerxes I (r. 486–465) launched the Second Persian invasion of Greece. At a crucial moment in the war, about half of mainland Greece was overrun by the Persians, including territories to the north of the Isthmus of Corinth. This was reversed by a Greek victory following the battles of Plataea and Salamis, during which Persia lost all of its footholds in Europe, and withdrew from it.
