The Tragedy of Julius Caesar is a history play and tragedy by William Shakespeare first performed in 1599. It is one of several plays written by Shakespeare based on true events from Roman history, such as Coriolanus and Antony and Cleopatra.
Set in Rome in 44 BC, the play depicts the moral dilemma of Brutus as he joins a conspiracy led by Cassius to murder Julius Caesar to prevent him from becoming dictator of Rome. Following Caesar's death, Rome is thrust into a period of civil war, and the republic the conspirators sought to preserve is lost forever.
Although the play is named Julius Caesar, Brutus speaks more than four times as many lines as the title character; and the central psychological drama of the play focuses on Brutus' struggle between the conflicting demands of honour, patriotism, and friendship. 
Among the most significant works William Shakespeare: Hamlet, Othello, King Lear, Macbeth, Orpheus, Romeo and Juliet, Julius Caesar, Troilus and Cressida, The Tempest, Venus and Adonis, Antony and Cleopatra, Measure for Measure, The Winter's Tale and many more.
