Casca and Cassius decide, on the night before the Assassination of Julius Caesar, that Mark Antony should live.
Julius Caesar, the Roman dictator, was assassinated by a group of senators on the Ides of March (15 March) of 44 BC during a meeting of the Senate at the Curia of Pompey of the Theatre of Pompey in Rome where the senators stabbed Caesar 23 times. They claimed to be acting over fears that Caesar's unprecedented concentration of power during his dictatorship was undermining the Roman Republic, and presented the deed as an act of tyrannicide. At least 60 senators were party to the conspiracy, led by Marcus Junius Brutus and Gaius Cassius Longinus. Despite the death of Caesar, the conspirators were unable to restore the institutions of the Republic. The ramifications of the assassination led to the Liberators' civil war and ultimately to the Principate period of the Roman Empire.
Publius Servilius Casca Longus (died c. 42 BC) was one of the assassins of Julius Caesar. He and several other senators conspired to kill him, a plan which they carried out on 15 March, 44 BC. Afterwards, Casca fought with the liberators during the Liberators' civil war. He is believed to have died by suicide after their defeat at the Battle of Philippi in 42 BC.
