Tryphenia was ruler when their father left to go into hiding, and threatened to kill PtolomyXI if he returned. So when Tryphenia was asleep some of PtolomyXI's friends killed her guards, and strangled her to death. Then Berinece took over the throne and her father came back to Egypt from where he had been hiding. He was upset that she had taken over, that he ordered her to be decapitated. Her head was brought before him on a silver platter!!!
When PtolomyXI died, Cleopatra became Pharaoh. She left Egypt to go sailing on the Nile to meet the people of Egypt. While she was gone Arsinoe took over the throne with her brother PotolomyXII. I think you can guess what happens to them?! The Romans chased Ptolomy down, and killed him. They took Arsinoe prisoner and put her in the dungeon. Cleopatra went to the dungeon and killed her when Ceaser was sleeping.
Cleopatra died from letting a poisonous snake bite her after Octavian was about to conquer Egypt. After she died, Egypt fell to the Roman Empire.
