Ptolemaic Kingdom

The Ptolemaic Kingdom (; Koine Greek: Πτολεμαϊκὴ βασιλεία, Ptolemaïkḕ basileía) or Ptolemaic Empire was an ancient Greek polity based in Egypt during the Hellenistic period. It was founded in 305 BC by the Macedonian Greek general Ptolemy I Soter, a companion of Alexander the Great, and ruled by the Ptolemaic dynasty until the death of Cleopatra VII in 30 BC. Reigning for nearly three centuries, the Ptolemies were the longest and final dynasty of ancient Egypt, heralding a distinct era of religious and cultural syncretism between Greek and Egyptian culture. Alexander the Great conquered Egypt in 332 BC during his campaigns against the Achaemenid Empire. Alexander's death in 323 BC was followed by the rapid unraveling of the Macedonian Empire.
