Think, whose power the killers of Caesar wanted to restore? Calculate how many years passed from the establishment of the republic to the seizure of power by Caesar in Rome?

The Roman senators who established republican rule were the rulers of Rome from 509 BC. It was the Senate who was in charge of the treasury, announced new laws, and was in charge of relations with other states. Caesar, having seized power in 45 BC, became the emperor, the sole ruler. The 460-year reign of the Senate is over.

The poisoners had as their goal the restoration of the republic and the new rise of the Senate. Among the conspirators was a friend of the emperor Brutus. The murder took place on March 15, 44 BC.
