The play opens with two tribunes (appointed leaders/officials of Rome) discovering the commoners of Rome celebrating Julius Caesar’s triumphant return from defeating the sons of his military rival, Pompey. The tribunes, insulting the crowd for their change in loyalty from Pompey to Caesar, attempt to end the festivities and break up the commoners, who return the insults. During the feast of Lupercal, Caesar holds a victory parade and a soothsayer warns him to “Beware the ides of March,” which he ignores. Meanwhile, Cassius attempts to convince Brutus to join his conspiracy to kill Caesar. Although Brutus, friendly towards Caesar, is hesitant to kill him, he agrees that Caesar may be abusing his power. They then hear from Casca that Mark Antony has offered Caesar the crown of Rome three times. Casca tells them that each time Caesar refused it with increasing reluctance, hoping that the crowd watching would insist that he accept the crown. He describes how the crowd applauded Caesar for denying the crown, and how this upset Caesar. On the eve of the ides of March, the conspirators meet and reveal that they have forged letters of support from the Roman people to tempt Brutus into joining. Brutus reads the letters and, after much moral debate, decides to join the conspiracy, thinking that Caesar should be killed to prevent him from doing anything against the people of Rome if he were ever to be crowned.

After ignoring the soothsayer, as well as his wife Calpurnia’s own premonitions, Caesar goes to the Senate. The conspirators approach him with a fake petition pleading on behalf of Metellus Cimber’s banished brother. As Caesar predictably rejects the petition, Casca and the others suddenly stab him; Brutus is last. At this point, Caesar utters the famous line “Et tu, Brute?”[2] (“And you, Brutus?”, i.e. “You too, Brutus?”), concluding with “Then fall, Caesar!”

The conspirators make clear that they committed this killing for the good of Rome, to prevent an autocrat. They prove this by not attempting to flee the scene. Brutus delivers an oration defending his actions, and for the moment, the crowd is on his side. However, Antony makes a subtle and eloquent speech over Caesar’s corpse, beginning with the much-quoted “Friends, Romans, countrymen, lend me your ears!”[3] In this way, he deftly turns public opinion against the assassins by manipulating the emotions of the common people, in contrast to the rational tone of Brutus’s speech, yet there is a method in his rhetorical speech and gestures: he reminds them of the good Caesar had done for Rome, his sympathy with the poor, and his refusal of the crown at the Lupercal, thus questioning Brutus’s claim of Caesar’s ambition; he shows Caesar’s bloody, lifeless body to the crowd to have them shed tears and gain sympathy for their fallen hero; and he reads Caesar’s will, in which every Roman citizen would receive 75 drachmas. Antony, even as he states his intentions against it, rouses the mob to drive the conspirators from Rome. Amid the violence, an innocent poet, Cinna, is confused with the conspirator Lucius Cinna and is taken by the mob, which kills him for such “offenses” as his bad verses.

Brutus next attacks Cassius for supposedly soiling the noble act of regicide by having accepted bribes. (“Did not great Julius bleed for justice’ sake? / What villain touched his body, that did stab, / And not for justice?”[4]) The two are reconciled, especially after Brutus reveals that his beloved wife committed suicide under the stress of his absence from Rome; they prepare for a civil war against Antony and Caesar’s adopted son, Octavius, who have formed a triumvirate in Rome with Lepidus. That night, Caesar’s ghost appears to Brutus with a warning of defeat. (He informs Brutus, “Thou shalt see me at Philippi.”[5])

At the battle, Cassius and Brutus, knowing that they will probably both die, smile their last smiles to each other and hold hands. During the battle, Cassius has his servant kill him after hearing of the capture of his best friend, Titinius. After Titinius, who was not captured, sees Cassius’s corpse, he commits suicide. However, Brutus wins that stage of the battle, but his victory is not conclusive. With a heavy heart, Brutus battles again the next day. He asks his friends to kill him, but the friends refuse. He loses and commits suicide by running on his sword, held for him by a loyal soldier.

The play ends with a tribute to Brutus by Antony, who proclaims that Brutus has remained “the noblest Roman of them all”[6] because he was the only conspirator who acted, in his mind, for the good of Rome. There is then a small hint at the friction between Antony and Octavius which characterizes another of Shakespeare’s Roman plays, Antony and Cleopatra.

The play, set in Verona, Italy, begins with a street brawl between Montague and Capulet servants who, like the masters they serve, are sworn enemies. Prince Escalus of Verona intervenes and declares that further breach of the peace will be punishable by death. Later, Count Paris talks to Capulet about marrying his daughter Juliet, but Capulet asks Paris to wait another two years and invites him to attend a planned Capulet ball. Lady Capulet and Juliet’s Nurse try to persuade Juliet to accept Paris’s courtship.

Meanwhile, Benvolio talks with his cousin Romeo, Montague’s son, about Romeo’s recent depression. Benvolio discovers that it stems from unrequited infatuation for a girl named Rosaline, one of Capulet’s nieces. Persuaded by Benvolio and Mercutio, Romeo attends the ball at the Capulet house in hopes of meeting Rosaline. However, Romeo instead meets and falls in love with Juliet. Juliet’s cousin, Tybalt, is enraged at Romeo for sneaking into the ball but is only stopped from killing Romeo by Juliet’s father, who does not wish to shed blood in his house. After the ball, in what is now famously known as the “balcony scene”, Romeo sneaks into the Capulet orchard and overhears Juliet at her window vowing her love to him in spite of her family’s hatred of the Montagues. Romeo makes himself known to her, and they agree to be married. With the help of Friar Laurence, who hopes to reconcile the two families through their children’s union, they are secretly married the next day.

Tybalt, meanwhile, still incensed that Romeo had sneaked into the Capulet ball, challenges him to a duel. Romeo, now considering Tybalt his kinsman, refuses to fight. Mercutio is offended by Tybalt’s insolence, as well as Romeo’s “vile submission”, and accepts the duel on Romeo’s behalf. Mercutio is fatally wounded when Romeo attempts to break up the fight, and declares a curse upon both households before he dies. (“A plague o’ both your houses!”) Grief-stricken and racked with guilt, Romeo confronts and slays Tybalt.

Benvolio argues that Romeo has justly executed Tybalt for the murder of Mercutio. The Prince, now having lost a kinsman in the warring families’ feud, exiles Romeo from Verona, under penalty of death if he ever returns. Romeo secretly spends the night in Juliet’s chamber, where they consummate their marriage. Capulet, misinterpreting Juliet’s grief, agrees to marry her to Count Paris and threatens to disown her when she refuses to become Paris’s “joyful bride”. When she then pleads for the marriage to be delayed, her mother rejects her.

Juliet visits Friar Laurence for help, and he offers her a potion that will put her into a deathlike coma or catalepsy for “two and forty hours”. The Friar promises to send a messenger to inform Romeo of the plan so that he can rejoin her when she awakens. On the night before the wedding, she takes the drug and, when discovered apparently dead, she is laid in the family crypt.

The messenger, however, does not reach Romeo and, instead, Romeo learns of Juliet’s apparent death from his servant, Balthasar. Heartbroken, Romeo buys poison from an apothecary and goes to the Capulet crypt. He encounters Paris who has come to mourn Juliet privately. Believing Romeo to be a vandal, Paris confronts him and, in the ensuing battle, Romeo kills Paris. Still believing Juliet to be dead, he drinks the poison. Juliet then awakens and, discovering that Romeo is dead, stabs herself with his dagger and joins him in death. The feuding families and the Prince meet at the tomb to find all three dead. Friar Laurence recounts the story of the two “star-cross’d lovers”, fulfilling the curse that Mercutio swore. The families are reconciled by their children’s deaths and agree to end their violent feud. The play ends with the Prince’s elegy for the lovers: “For never was a story of more woe / Than this of Juliet and her Romeo.
