The powerful Egyptian queen who seduced Julius Caesar was Cleopatra VII. As the last active ruler of the Ptolemaic Kingdom of Egypt, Cleopatra sought to strengthen her position and consolidate power amid political turmoil. Her relationship with Caesar began in 48 BCE, when she sought his support against her brother Ptolemy XIII. Cleopatra's intelligence, charm, and political acumen allowed her to navigate complex alliances. After Caesar's assassination in 44 BCE, she became involved with Mark Antony, further influencing Roman politics. Cleopatra remains a symbol of intrigue and power in ancient history.
