Julius Caesar was a general in the Roman army. He won a big battle and returned to Rome. Most of the people loved him but some people envied him because he was powerful. They decided to kill him. Brutus was Caesar’s friend. A man called Cassius asked Brutus to join the plot against Caesar. ‘It is for the good of Rome,’ he said. The plotters decided not to kill Mark Antony, another important Roman. It was a very bad decision. The plotters decided to kill Caesar on 15^th.March. The night before, Caesar’s wife, Calpurnia, had a dreadful dream about her husband. In her dream, Caesar died at work in the government building. She tried to stop him going to work. But he didn’t listen to his wife, and went. The plotters killed him. Caesar’s friend hit him last of all. After Caesar s death, Mark Antony spoke at Caesar’s funeral. He told the crowd about Caesar’s good qualities and actions. The crowd got angry, and Cassius and Brutus had to leave the city. A war started between the supporters of Brutus and Cassius and the supporters of Mark Antony. At first, Brutus and Cassius won some battles. However, Mark Antony finally won the war, and the other two men died. When Mark Antony saw the body of Brutus, he was very sad. ‘He was the noblest Roman of them all,’ he said. ‘The other plotters killed Caesar because they hated him.
