"The Ptolemaic dynasty (/ˌtɒlɪˈmeɪɪk/; Ancient Greek: Πτολεμαῖοι, Ptolemaioi), sometimes also known as the Lagids (/ˈlædʒɪdz/) or Lagidae (/ˈlædʒɪdi/; Λαγίδαι, Lagidai, after Lagus, Ptolemy I´s father), was a Macedonian Greek royal family, which ruled the Ptolemaic Kingdom in Egypt during the Hellenistic period. Their rule lasted for 275 years, from 305 to 30 BC. They were the last dynasty of ancient Egypt.
Ptolemy, one of the seven somatophylakes (bodyguards) of Macedon who served as Alexander the Great´s generals and deputies, was appointed satrap of Egypt after Alexander´s death in 323 BC. In 305 BC, he declared himself Ptolemy I, later known as Sōter "Saviour". The Egyptians soon accepted the Ptolemies as the successors to the pharaohs of independent Egypt. Ptolemy´s family ruled Egypt until the Roman conquest of 30 BC." - (en.wikipedia.org 12.12.2019)
