Ptolemy I Soter

Ptolemy I Soter (/ˈtɒləmi/; Greek: Πτολεμαῖος Σωτήρ, Ptolemaîos Sōtḗr "Ptolemy the Saviour"; c. 367 BC – January 282 BC) was a companion and historian of Alexander the Great of the Kingdom of Macedon in northern Greece who became ruler of Egypt, part of Alexander's former empire. Ptolemy was pharaoh of Ptolemaic Egypt from 305/304 BC to his death. He was the founder of the Ptolemaic dynasty which ruled Egypt until the death of Cleopatra in 30 BC, turning the country into a Hellenistic kingdom and Alexandria into a centre of Greek culture.
