Ptolemy I Soter
Ptolemy I Soter(" Ptolemaîos SōtḗrPtolemy the Savior"; 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 center of Greek culture.
Ptolemy I was the son of Arsinoe of Macedon by either her husband Lagus or Philip II of Macedon, the father of Alexander.
Ptolemy was one of Alexander's most trusted companions and military officers.
After the death of Alexander in 323 BC, Ptolemy retrieved his body as it was en route to be buried in Macedon, placing it in Memphis instead, where it was later moved to Alexandria in a new tomb.
Afterwards he joined a coalition against Perdiccas, the royal regent over Philip III of Macedon.
The latter invaded Egypt but was assassinated by his own officers in 320 BC, allowing Ptolemy I to consolidate his control over the country.
After a series of wars between Alexander's successors, Ptolemy gained a claim to Judea in southern Syria which was disputed with the Syrian king Seleucus I Nicator, his former ally.
He also took control of Cyprus and Cyrenaica, the latter of which was placed under the control of Ptolemy's stepson Magas.
