What Does Et Tu Brute Mean?

Et Tu Brute Meaning

Definition: And you, Brutus?

It is common for people to use this expression when someone whom they did not expect has betrayed them.

Origin of Et Tu Brute

This is one of many expressions that the famous English playwright William Shakespeare popularized. This quote appeared in the play Julius Caesar, a tragedy likely written around the year 1599.

This play revolves around the historical figure of a leader of Rome, Julius Caesar. In the play, other political leaders, senators, were worried that Caesar would become the emperor of Rome. They did not want Rome to have an emperor; they wanted Rome to be a republic. Therefore, they conspired to murder Caesar.

One of the conspirators, Brutus, was a friend of Caesar’s. He did not want to kill Caesar, but believed he had to in order to prevent Caesar from becoming an emperor and, as a result, destroying the Republic of Rome.

When Brutus and the other senators assassinated Caesar, Caesar spoke to Brutus, asking him how he could betray him in such a way through the Latin question, Et tu, Brute?
