The people who murdered julius caesar want to give power to the senate what resulted from their action

The assassination of Julius Caesar was the result of a conspiracy by many Roman senators led by Gaius Cassius Longinus, Decimus Junius Brutus Albinus, and Marcus Junius Brutus.[1][2] They stabbed Julius Caesar to death in a location adjacent to the Theatre of Pompey on the Ides of March (March 15), 44 BC. Caesar was the dictator of the Roman Republic, having recently been declared dictator perpetuo by the Senate of the Roman Republic. This declaration made several senators fear that Caesar wanted to overthrow the Senate in favor of tyranny. The conspirators were unable to restore the Roman Republic, and the ramifications of the assassination led to the Liberators' civil war and ultimately to the Principate period of the Roman Empire.
