Artaxerxes III of Persia (c. 425 BC – 338 BC) (Persian: اردشير سوم) (Old Persian: 𐎠𐎼𐎫𐎧𐏁𐏂𐎠,transliterated as Artaxšaçā), was the Great King (Shah) of Persia and the eleventh Emperor of the Achaemenid Empire, as well as the first Pharaoh of the 31st dynasty of Egypt. He was the son and successor of Artaxerxes II and was succeeded by his son, Arses of Persia (also known as Artaxerxes IV). His reign coincided with the reign of Philip II in Macedon and Nectanebo II in Egypt. Before ascending the throne Artaxerxes was a satrap and commander of his father's army. Artaxerxes came to power after one of his brothers was executed, another committed suicide, the last murdered and his father, Artaxerxes II died at the age of 86. Soon after becoming king, Artaxerxes murdered all of the royal family to secure his place as emperor. He started two major campaigns against Egypt. The first campaign failed, and was followed up by rebellions throughout the western empire. In 343 BC, Artaxerxes defeated Nectanebo II, the Pharaoh of Egypt, driving him from Egypt, stopping a revolt in Phoenicia on the way. In Artaxerxes' later years, Philip II of Macedon's power was increasing in Greece, where he tried to convince the Greeks to revolt against Achaemenid Persia. His activities were opposed by Artaxerxes, and with his support, the city of Perinthus resisted a Macedonian siege. There is evidence for a renewed building policy at Persepolis in his later life, where Artaxerxes erected a new palace and built his own tomb, and began long-term projects like the Unfinished Gate. According to a Greek source, Diodorus of Sicily, Bagoas poisoned Artaxerxes, but a cuneiform tablet (now in the British Museum) suggests that the king died from natural causes.
