This is a timeline about a world where Caesar survives the Roman Senate's assassination attempt. Just a heads up.
46 BC: Caesar defeats Cato and is declared Dictator for another ten years.
45 BC: Caesar begins the Julian calendar and defeats the last remnants of Pompey's faction at the Battle of Munda.
44 BC: On March 14, Marc Anthony discovers the plot to kill Caesar, and the next morning, attempts to head Caesar off before he is killed. Trebonius attempts to stop him as he enters the Theatre of Pompey, but fails. Bursting into the room, Anthony distracts the conspirators, who look up just as Casca attempts to stab Caesar, and misses. Caesar seizes the dagger from Casca and cries to Anthony, "Help, brother!" Anthony draws his Spanish sword and menacingly advances upon the crowd of conspirators. Knowing that they are no match for the two experienced soldiers, the Senators surrender, dropping their arms. Marcus Junius Brutus the Younger, having hung behind as the Senators attacked, is not among them. They are quickly taken outside by Marc Anthony's personal guard, where Caesar makes an impromptu speech to a rapidly gathering crowd, revealing the plot against him. Enraged, the crowd, mostly consisting of Caesar-loving plebians, begins jeering at the Senators. They are quickly slain by Anthony's guard. Over the rest of the year, Caesar, finally convinced of the danger inherent in leaving his enemies unpunished, carries out several purges of the aristocracy of Rome, devastating particularly the Junia family, though sparing Brutus for his perceived loyalty during the attack. This angers Brutus and he begins formulating a second plot to kill Caesar, traveling to Apollonia on a pretense, where he begins poisoning the young Octavian's mind against his father. Meanwhile, in Egypt, Caesar's mistress Cleopatra continues urging her lover to accept Caesarion as his heir. He begins seriously considering it, as she was one of the first to rush to his side after the attempted assassination.
