Cleopatra

Cleopatra (69-30 BC) was the last of the Ptolemaic rulers of Egypt. She was notorious in antiquity and has been romanticized in modern times as the lover of Julius Caesar and Mark Antony.
Third daughter of Ptolemy XII Auletes, Cleopatra VII Philopator (her full name) learned her political lessons by watching the humiliating efforts of her father to maintain himself on the throne of Egypt by buying the support of powerful Romans. When he died in 51 B.C., the ministers of Cleopatra's brother Ptolemy XIII feared her ambition to rule alone and drove her from Egypt in 48.
Cleopatra and Mark Antony :
In the winter of 41-40 Antony followed Cleopatra to Alexandria, where he reveled in the pleasures of the Ptolemaic court and the company of the Queen. Cleopatra hoped to tie him emotionally to her, but Antony left Egypt in the spring of 40.

In the autumn of 37 Antony sent his wife, Octavia, back to Italy on the excuse that she was pregnant and went to Antioch to make final preparations for his invasion of Parthia. In Antioch he again sent for Cleopatra and went through a ritualistic marriage not recognized under Roman law. He also recognized the twins Cleopatra had with him and made extensive grants of territory to her, including Cyprus, Cyrene, and the coast of Lebanon, all of which had once been part of the Ptolemaic empire.

In 36 Cleopatra returned to Alexandria to await the birth of her third child by him. The failure of the Parthian campaign and Octavian's exploitation of Antony's misadventure drove Antony further into the arms of Cleopatra, who gave him immense financial help in rebuilding his shattered army. When Antony defeated Artavasdes of Armenia in 34, he celebrated his triumph not in Rome but in Alexandria. On the following day he declared Cleopatra and Ptolemy Caesarion joint rulers of Egypt and Cyprus and overlords of all lands west and east of the Euphrates For Cleopatra this meant the potential union of the Ptolemaic and Seleucid empires under her control, and Antony staked out his claims on the wealth of Egypt for the coming struggle with Octavian.
In Italy, Octavian used the donations at Alexandria and Antony's relations with Cleopatra to turn public opinion against him. The Battle of Actium on September 2, 31, fought for the control of the Roman Empire, led to the final disaster. Because Cleopatra's money built the fleet and supported it, she insisted on fighting at sea. When she fled from the battle with the war chest, Antony had little choice but to follow.

After Actium, Cleopatra tried to negotiate with Octavian for the recognition of her children as her successors in Egypt. But as his price Octavian demanded the death of Antony, and Cleopatra refused. After the final battle outside Alexandria on August 1, 30 B.C., in which his troops deserted him, Antony stabbed himself when he received a false report that Cleopatra was already dead. Antony died in Cleopatra's arms inside her mausoleum, where she had barricaded herself with the treasures of the Ptolemies to keep them from Octavian.

Tricked into surrendering herself, Cleopatra tried again to negotiate with Octavian. Rebuffed, she carefully planned her own death. On August 10, after paying last honors to Antony, she retired to her quarters for a final meal. How Cleopatra died is not known, but on her left arm were found two tiny pricks, presumably from the bite of an asp.
