The play Julius Caesar by William Shakespeare depicts the conspiracy to assassinate the Roman dictator Julius Caesar. Some Roman senators, including Brutus and Cassius, fear that Caesar desires to be king and undermine the Roman republic. They conspire to kill Caesar on the Ides of March. However, Mark Antony later turns the public against the conspirators with a stirring funeral speech praising Caesar. This leads Brutus and Cassius to raise an army to fight Antony and Octavian, culminating in their suicide after defeat at the Battle of Philippi. The play focuses on the moral dilemma of whether to kill a power-hungry leader to preserve a republic.
