The Ptolemaic dynasty /ˌtɒləˈmeɪ.ᵻk/ (Ancient Greek: Πτολεμαῖοι, Ptolemaioi), sometimes also known as the Lagids /ˈlædʒᵻdz/ or Lagidae /ˈlædʒᵻˌdiː/ (Ancient Greek: 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. 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.
