Julius Caesar opens with the tribunes (the elected representatives of the people) reproaching the commoners for celebrating Caesar’s victory over Pompey the Great in the recent civil war. We later learn the tribunes are condemned to death for their actions. At the festival of Lupercal, a fortune-teller advises Caesar to beware of a specific date, the Ides of March. Meanwhile, the conspirator Cassius and Caesar’s friend Brutus nervously discuss how Caesar is amassing more power than is healthy in a republic. Brutus reluctantly agrees with Cassius’s plan to assassinate Caesar as the only way to avoid tyranny. Brutus’s wife, Portia, tries to persuade him to explain what is going on, showing him a self-inflicted wound on her leg as proof of her equality to men in fearlessness and resolve. Caesar goes to the Capitol, despite the warning of his wife, Calphurnia, where the fortune-teller reminds him the Ides of March are not yet over. He is stabbed by all of the conspirators – Brutus last.
Brutus, against Cassius’s advice, agrees to let Mark Antony speak after him at the funeral. Brutus’s speech initially pursuades the crowd with the argument that Caesar had to die for the sake of the Republic, but Antony reminds the people of Caesar’s virtues, shows them his corpse and reads Caesar’s will, which leaves his money and private gardens to the people. Antony’s speech provokes a riot that turns into civil war. Brutus is visited by Caesar’s ghost on the eve of the Battle of Philippi. Cassius and Brutus are defeated in battle the next day and have their followers help them commit suicide. Antony and Octavius (Julius Caesar’s nephew) distinguish Brutus from the other conspirators, reflecting that his motives had been honourable.
