Ancient Egypt was an ancientcivilization of eastern North Africa, concentrated along the lower reaches of the Nile River in what is now the modern country of Egypt. The civilization coalesced around 3150 BC with the political unification of Upper and Lower Egypt under the first pharaoh, and it developed over the next two millennia. Ancient Egypt reached its pinnacle during the New Kingdom, after which it entered a period of slow decline. Egypt was conquered by a succession of foreign powers in this late period, and the rule of the pharaohs officially ended in 31 BC when the early Roman Empire conquered Egypt and made it a province.
Egypt has left a lasting legacy for all to see. Its art and architecture has been widely copied, and its antiquities have been carried off to the far corners of the world. Egypt's monumental ruins have inspired the imaginations of travelers and writers for centuries. A newfound respect for antiquities and excavations in the early modern period led to the scientific investigation of Egyptian civilization and a greater appreciation of its cultural legacy for the earth.
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 brother was 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 but 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.
