Upon the accession of Xerxes, Egypt again rebelled, this time possibly under Psamtik IV, although different sources dispute that detail. Xerxes quickly quelled the rebellion, installing his brother Achaemenes as satrap. Xerxes ended the privileged status of Egypt held under Darius, and increased supply requirements from the country, probably to fund his invasion of Greece. Furthermore, Xerxes promoted the Zoroastrian god Ahura Mazda at the expense of traditional Egyptian deities, and permanently stopped the funding of Egyptian monuments. Xerxes was murdered in 465 BC by Artabanus, beginning a dynastic struggle that ended with Artaxerxes I being crowned the next King and Pharaoh.
