context: The last ruler from the Ptolemaic line was Cleopatra VII, who committed suicide following the burial of her lover Mark Antony who had died in her arms (from a self-inflicted stab wound), after Octavian had captured Alexandria and her mercenary forces had fled. The Ptolemies faced rebellions of native Egyptians often caused by an unwanted regime and were involved in foreign and civil wars that led to the decline of the kingdom and its annexation by Rome. Nevertheless, Hellenistic culture continued to thrive in Egypt well after the Muslim conquest.
