Ptolemy I Soter
Updated: Wikipedia source
Ptolemy I Soter (; Greek: Πτολεμαῖος Σωτήρ, Ptolemaîos Sōtḗr, "Ptolemy the Savior"; c. 369/68 BC – January 282 BC) was a Macedonian Greek general, historian, and successor of Alexander the Great who went on to found the Ptolemaic Kingdom centered on Egypt. Ptolemy was king and pharaoh of Ptolemaic Egypt from 305/304 BC to his death in 282 BC, and his descendants continued to rule Egypt until 30 BC. During their rule, Egypt became a thriving bastion of Hellenistic civilization and Alexandria a great seat 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. However, the latter is unlikely and may be a myth fabricated to glorify the Ptolemaic Dynasty. 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. Perdiccas 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 Seleucid king Seleucus I. He also took control of Cyprus and Cyrenaica, the latter of which was placed under the control of Ptolemy's stepson Magas. Ptolemy also commanded the construction of the Library of Alexandria and of the Lighthouse of Alexandria, one of the Seven Wonders of the Ancient World. Ptolemy I may have married Thaïs, his mistress during the life of Alexander; he is known to have married the Persian noblewoman Artakama on Alexander's orders. He later married Eurydice, daughter of the Macedonian regent Antipater; their sons Ptolemy Keraunos and Meleager ruled in turn as kings of Macedon. Ptolemy's final marriage was to Eurydice's cousin and lady-in-waiting, Berenice I. Upon his death, he was succeeded by his son with Berenice, Ptolemy II.
