在这段历史的转折点上，盖萨里斯·尤利乌斯·凯撒逃离了庞培的追击，来到了埃及。在克罗迪斯四世的庇护下，他获得了一次对抗庞培的机会。伯提诺斯将庞培杀害，并将他的头颅送给了盖萨里斯，以此作为向他表示忠诚的一种方式。然而，这并没有赢得凯撒的心。他Eliminated his sister Cleopatra VII from the throne, but this action did not earn him her favor. Meanwhile, Cleopatra VII was also seeking to use Caesar's influence to secure her position on the throne. She disguised herself as a merchant and wrapped herself in a large blanket, sending her servants to present themselves before Caesar. When he saw her through the blanket, he was immediately captivated by her beauty and charm. The young queen's stunning looks and wit had a profound effect on Caesar, who soon ordered that Cleopatra VII and Ptolemy XIII be reinstated as co-regents alongside their father.
Subsequently, Pompey was defeated in the Battle of Alexandria and killed shortly after. With Caesar victorious in Egypt but unable to annex it into Rome due to political circumstances, Cleopatra VII managed to secure his promise that she would be buried beside him when he died. After Caesar's assassination in 44 BCE, Cleopatra VII returned with Ptolemy XIV (who had been eliminated from power) back to Egypt where she ruled alongside him until his death two years later.
Cleopatra VII then poisoned Ptolemy XIV and took sole control of the kingdom along with one of Caesar's sons by an earlier marriage named Alexander Helios (meaning "Sun King"). This son was proclaimed as divine offspring of Zeus by his mother. In Rome meanwhile, Gaius Julius Caesar Octavianus (later known as Augustus), one half-brother or full brother of Alexander Helios through adoption or descent respectively,[4] began building up power during Mark Antony’s campaigns against Brutus’ forces at Mutina.
When news reached Mark Antony that Octavian had attacked Illyricum while being appointed consul for 43 BC without consulting him or any other triumvirate members,[5] he felt threatened enough by Octavian’s growing strength that he decided it best if they could have separate territories within Roman Republic.[6]
Afterward both men agreed upon division: Mark Antony taking Eastern regions including Greece & Asia Minor; while Octavian controlled Western regions such as Italy & Spain.,[7][8].
