Cleopatra died in August 30 B.C. at the age of 39. She committed suicide after surrendering to the Roman emperor Octavian. Marc Antony, partner of Cleopatra, previously committed suicide following his defeat to Roman troops in battle.
In 55 B.C., Cleopatra became co-ruler of the Egyptian empire alongside her father Ptolemy XII. Julius Caesar helped restore Cleopatra to the throne following the death of her father and an attack on her power by one of her brothers. Cleopatra was the final pharaoh to rule Egypt. At the height of her power, Cleopatra ruled over an empire that included Egypt, Cyprus and other territories in the Middle East, including parts of Libya.
