Xerxes I of Persia(519–465 BC), was the 4th King of Kings of Persia. In 465 BC, Xerxes was murdered by Artabanus, the commander of the royal bodyguard and the most powerful official in the Persian court. Although Artabanus bore the same name as the famed uncle of Xerxes, a Hyrcanian, his rise to prominence was due to his popularity in religious quarters of the court and harem intrigues. He put his seven sons in key positions and had a plan to dethrone the Achamenids.
The Battle of Mycale was one of the two major battles that ended the second Persian invasion of Greece during the Greco-Persian Wars. It took place on or about August 27, 479 BC on the slopes of Mount Mycale, on the coast of Ionia, opposite the island of Samos. The battle was fought between an alliance of the Greek city-states, including Sparta, Athens and Corinth, and the Persian Empire of Xerxes I.
