1. Marcus Brutus and Gaius Cassius Longinus: Brutus and Cassius were the primary leaders of the conspiracy to assassinate Julius Caesar. After Caesar's death, they fled Rome and gathered an army to fight against the forces loyal to Caesar's supporters, led by Mark Antony and Octavius Caesar. In the Battle of Philippi, Brutus and Cassius' forces were defeated. In the aftermath, they committed suicide to avoid capture.
2. Decimus Junius Brutus: Decimus Brutus was one of the conspirators who joined Brutus and Cassius. He held the position of governor of Gallia Cisalpina and used his influence to gain support for the conspiracy. After Caesar's assassination, he was named the governor of Macedonia, but later lost the support of the Roman Senate. He was subsequently defeated and killed in battle by Mark Antony's forces.
3. Gaius Trebonius: Trebonius was another prominent conspirator. He was responsible for holding Caesar during the assassination and stabbing him first. After the assassination, he went to Asia as proconsul but was murdered by Publius Cornelius Dolabella, a supporter of Caesar.
4. Publius Servilius Casca: Casca was the conspirator who delivered the first blow to Caesar. After the assassination, he fled to Rome with the other conspirators but was pursued by Caesar's supporters. Casca managed to escape to Macedonia, but little is known about his ultimate fate.
5. Lucius Tillius Cimber: Cimber was responsible for distracting Caesar during the assassination. After the act, he fled to Macedonia with other conspirators. However, he was eventually captured and killed by Octavius Caesar's forces.
These are some of the key conspirators in the tragedy of Julius Caesar, and they all faced various consequences for their actions, as depicted by Shakespeare in the play.
