At the senate Metellus gives a petition requesting Caesar to recall his brother, Publius who had been banished from Rome. Caesar answers that since Publius had been banished by lawful decree; there is no just cause for absolving his guilt. Brutus and Cassius kneel at Caesar’s feet and repeat Metellus’s plea. Caesar answers that he will not change his mind, declaring himself to be as ‘constant as the Northern Star’. Caesar is murdered in the Senate House by the conspirators. Recognizing that the Brutus, too, has joined with the conspirators, Caesar speaks his last word:”Ettu, Brute?”-Then falls Caesar.
Antony enters and pretends that he agrees with the conspirators actions. Addressing Caesar’s departed spirit; Antony asks to be pardoned for making peace with the conspirators over his dead body.
However, Antony is granted permission to speak at Caesar's funeral. Brutus and Cassius enter the Forum with a Crowd of Plebeians. Brutus speaks first at the funeral to explain their reasons for killing Caesar. He feared that the Romans would live as slave under Caesar’s leadership. The people seem to accept his explanation.
Brutus explains to the crowd that Antony had no part in the conspiracy. And then Antony enters with Caesar’s body. Antony says that he has come to bury Caesar, not to praise him. Throughout his speech, Antony never really says anything bad about Brutus and the others, but he talks about Caesar being such a great and noble man willing to sacrifice all for his people. He reminds the plebeians of the day when he offered the crown to Caesar three times, Caesar refused and three times. He insists that as they all loved Caesar once, they should mourn for him.
The Plebeians are touched. They become angry and a mob runs through the streets in search of the conspirators. Battle plans are made as well as a list of people supportive of Brutus and the conspirators to be killed. There is a battle between the armies of Octavius Caesar and Antony Clash with those of Brutus and Cassius at Philippi and Sardis. Finally Brutus and Cassius are defeated and both commit suicide.
