Ptolemaic Kingdom capital Alexandria
Background
In 332 BC, Alexander the Great, King of Macedon, invaded Egypt, which at the time was a satrapy of the Achaemenid Empire known as the Thirty-first Dynasty under Emperor Artaxerxes III. He visited Memphis, and travelled to the oracle of Amun at the Siwa Oasis. The oracle declared him to be the son of Amun.
Alexander conciliated the Egyptians by the respect he showed for their religion, but he appointed Macedonians to virtually all the senior posts in the country, and founded a new Greek city, Alexandria, to be the new capital. The wealth of Egypt could now be harnessed for Alexander's conquest of the rest of the Achaemenid Empire. Early in 331 BC he was ready to depart, and led his forces away to Phoenicia. He left Cleomenes of Naucratis as the ruling nomarch to control Egypt in his absence. Alexander never returned to Egypt.
