Caesar was named "dictator for life" by the Roman Senate. Some of the senators, such as Gaius Cassius Longinus, Decimus Junius Brutus Albinus, and Marcus Junius Brutus, feared that he would take the Senate power and become king or emperor, so they decided to kill him.

After Caesar’s death, Augustus expanded the powers of Rome’s leader, for example by deifing him.
