What were the last words of Julius Caesar before his death?

Julius Caesar was a leader who was killed by a large group of conspirators. However, these conspirators were not thugs in Rome. Instead, they were senators who helped Caesar lead the country. The other unusual thing about this death was that there were about sixty of them. Plus, some of the senators were friends of Julius Caesar.

The last senator to stab Julius Caesar to death was Brutus who was a good friend of Caesar. In the days before the murder, Cassius, another conspirator and ringleader of the murder talked Brutus into helping kill Caesar. After much convincing, Brutus agreed. When Brutus stepped forward to stab Caesar, Caesar looked at Brutus and said, “Et tu, Brute” in Latin which means “And you too, Brutus.”

Et Tu Brute is a Latin phrase meaning even you Brutus? It has been professed that the words can be interpreted as a curse or warning. Caesar adapted the verbiage of a Greek sentence which to the Romans had since become proverbial. Roughly translated it means, "You too Brutus?" Caesar asks it in the form of a question because he believed that Caesar was his loyal friend.

The underlying message is betraying your friends and stabbing them in the back. Brutus was the last to stab Caesar, and his question demonstrates his surprise by what Brutus is saying and the fact that his friend Brutus participated in the plot to overthrow him.
