The gist

Othello, a Moorish general serving Venice, marries Desdemona, a senator's daughter, in secret. His ensign Iago resents being passed over for promotion in favor of Cassio and sets out to destroy them all. In Cyprus, Iago gets Cassio drunk and disgraced, then persuades Othello that Desdemona is having an affair with Cassio. His proof is a handkerchief that Othello gave his wife, which Iago's own wife picked up when Desdemona dropped it. Shakespeare shows how suggestion works on a proud mind, how an outsider's insecurities can be used against him, and how jealousy needs very little evidence to kill.

Key ideas

  1. 01

    Suggestion is stronger than accusation

    Iago never accuses Desdemona outright in the temptation scene. He hesitates, echoes Othello's words back, says he would rather not speak, and warns against jealousy. Each refusal makes Othello demand more. Shakespeare shows that a hint lets the listener supply the worst version himself, so the lie feels like his own discovery. The example is "Ha, I like not that," four words spoken as Cassio leaves Desdemona, which start the whole collapse.

  2. 02

    The appearance of honesty is a weapon

    Everyone in the play calls Iago honest. Othello trusts him with his wife, Cassio asks his advice, and Desdemona turns to him for comfort after Othello calls her a whore. Iago uses this reputation as his main tool. He tells the truth in small ways so his lies pass. Shakespeare's point is that people judge honesty by manner and history, not by checking facts. The man who seems most loyal is the one doing the damage.

  3. 03

    Jealousy feeds on itself

    Iago calls jealousy the green-eyed monster that mocks the meat it feeds on. Once Othello doubts, everything confirms the doubt: Desdemona's pleading for Cassio, her lost handkerchief, Cassio's laughter about another woman. Emilia later says jealous people are not jealous for a cause; they are jealous because they are jealous. The play shows that suspicion turns neutral facts into evidence. Othello asks for ocular proof and accepts a handkerchief and a story told secondhand.

  4. 04

    The outsider's insecurity is the opening

    Othello is a Black man and a soldier in a white, mercantile city that needs him and does not accept him. Brabantio welcomes him as a guest but cannot believe his daughter would marry him without witchcraft. Iago works on this gap. He reminds Othello that Desdemona deceived her father and that Venetian women hide their tastes. Othello begins to doubt that anyone like her could love someone like him. Shakespeare shows racism as a pressure that turns into self-doubt.

  5. 05

    Reputation is both empty and everything

    Cassio, dismissed after the drunken fight, mourns his lost reputation as the immortal part of himself. Iago tells him that reputation is an idle thing, often got without merit and lost without deserving. Yet Iago's entire plot runs on reputations: his own for honesty, Cassio's for charm, Desdemona's for virtue. Shakespeare shows that what others think of you shapes your fate, whether or not it matches what you have done.

  6. 06

    Silence and obedience do not protect women

    Desdemona does everything her world asks of a good wife. She defends her husband, obeys him, forgives his blow in public and lays out her wedding sheets on the night he means to kill her. None of it saves her. Emilia, who has kept quiet about her husband's demands, finally speaks against the men in the willow scene. Shakespeare gives the women the play's clearest moral voice, and shows how little that voice weighs against a man's suspicion.

  7. 07

    The villain who refuses to explain

    When Iago's plot is exposed, Othello asks why he did it. Iago answers that what they know, they know, and that he will never speak again. Desdemona, Emilia and Roderigo are dead, and Othello has killed himself. Shakespeare denies the audience a single clear motive. Iago has offered several during the play, none of them enough. The silence makes his evil feel more frightening, because it cannot be reasoned with or explained away.

Full summary

A tragedy of trust and jealousy

Othello is William Shakespeare's tragedy about a Black general in the service of Venice who is tricked by his own officer into believing that his wife is unfaithful. Shakespeare wrote it around 1603 or 1604. The first recorded performance was at the royal court in Whitehall on November 1, 1604. It was first printed in 1622, and a longer text appeared in the First Folio of 1623. The plot comes from an Italian story in Giraldi Cinthio's collection Gli Hecatommithi (1565).

The play is tighter than Shakespeare's other great tragedies. It has no subplot, no ghost and no battle. The Turkish fleet that threatens Cyprus sinks in a storm before the fighting begins, so the only war is the one inside Othello's mind. The engine of that war is one man, Iago, who speaks more lines than the hero and tells the audience his plans as he makes them.

The main characters:

  • Othello, a Moor (a man of North African descent), the Venetian army's most trusted general.
  • Desdemona, the daughter of a Venetian senator, who marries Othello in secret.
  • Iago, Othello's ensign, or flag bearer, who presents himself as honest and plots everyone's ruin.
  • Cassio, a young Florentine soldier whom Othello promotes to lieutenant over Iago.
  • Emilia, Iago's wife and Desdemona's attendant.
  • Roderigo, a foolish Venetian gentleman who wants Desdemona and pays Iago to help him.
  • Brabantio, Desdemona's father.
  • Bianca, a courtesan in Cyprus who loves Cassio.

The main themes are jealousy, the power of suggestion, race and the outsider, reputation, and the gap between honesty and the appearance of honesty.

Act 1: the elopement in Venice

The play opens at night in a Venetian street. Iago complains to Roderigo that Othello has made Cassio his lieutenant, a man with book learning and no battle experience, and left Iago as ensign. Iago says he follows Othello only to serve his own turn. He sums himself up: "I am not what I am."

The two men wake Brabantio and shout that his daughter has run off with Othello. Iago uses crude animal images of a Black man and a white woman to inflame him. Brabantio, who had welcomed Othello into his home, rouses his household and goes to find them.

At the same time, news arrives that a Turkish fleet is heading for Cyprus, a Venetian colony. The Duke and the senators summon Othello. Brabantio arrives and accuses Othello of winning his daughter with witchcraft and drugs.

Othello answers calmly. He tells the Senate that Brabantio often invited him to tell the story of his life: battles, captivity, slavery and strange lands. Desdemona listened and wept, and she loved him for the dangers he had passed. Desdemona herself comes and confirms it. She owes duty to her father, she says, but now her duty is to her husband, as her mother's was to Brabantio. The Duke accepts the marriage and sends Othello to defend Cyprus. Desdemona asks to go with him. Brabantio leaves with a warning to Othello: she has deceived her father, and she may deceive him.

Alone with Roderigo, Iago tells him to "put money in thy purse" and promises that Desdemona will tire of the Moor. Then, in a soliloquy, Iago says he hates Othello and repeats a rumor that Othello has slept with his wife, Emilia. He does not know if it is true, but he will act as if it were. His plan is to make Othello believe that Cassio is too familiar with Desdemona.

Act 2: the drinking scene in Cyprus

A storm wrecks the Turkish fleet. The Venetians land in Cyprus one ship at a time. Cassio greets Desdemona with courtly manners and takes her hand. Iago watches and says to himself that with as small a web as this he will catch as great a fly as Cassio.

Othello arrives and greets his wife with joy so complete that he says he could die now. Iago tells Roderigo that Desdemona already loves Cassio and persuades him to provoke Cassio that night.

The island celebrates the victory and the marriage. Cassio is in charge of the watch. He says he has a poor head for drink, but Iago pushes wine on him. Roderigo provokes him, Cassio chases him, and when the former governor Montano tries to stop the fight, Cassio wounds him. Iago has the alarm bell rung. Othello arrives, hears Iago's reluctant and carefully loaded account, and dismisses Cassio from his post.

Cassio is devastated. He cries that he has lost his reputation, the immortal part of himself. Iago, as a friend, tells him that reputation is an idle thing and advises him to ask Desdemona to plead his case. Then, alone, Iago explains the real plan: while Desdemona pleads for Cassio, he will pour poison into Othello's ear, suggesting that she does it out of lust.

Act 3: the temptation and the handkerchief

Cassio asks Emilia to arrange a meeting with Desdemona, who promises to plead for him and not give up. When Othello and Iago approach, Cassio leaves in a hurry. Iago mutters, "Ha, I like not that," and the poison begins.

Desdemona asks Othello again and again to restore Cassio. He agrees to see Cassio soon, and she leaves. Then comes the long temptation scene (Act 3, Scene 3), the center of the play. Iago never makes a direct charge. He hesitates, half speaks, warns Othello to beware of jealousy, the "green-eyed monster," and reminds him that Desdemona deceived her father to marry him. He suggests that a Venetian woman's tastes might turn back to men of her own country. Othello begins to doubt himself: he is Black, he is older, and he lacks the smooth talk of courtiers.

Othello demands proof he can see. The proof falls into Iago's hands by chance. Desdemona offers to bind Othello's aching head with her handkerchief, the first gift he gave her. He pushes it away and it drops. Emilia picks it up and gives it to Iago, who has often asked her to steal it. Iago plans to leave it in Cassio's room.

Iago then invents evidence. He claims he heard Cassio talk in his sleep about Desdemona, and that he saw Cassio wipe his beard with her handkerchief. Othello kneels and swears revenge. Iago kneels with him and swears to serve. Othello makes Iago his lieutenant and orders him to kill Cassio within three days.

Othello asks Desdemona for the handkerchief. He tells her it has magic in it: an Egyptian charmer gave it to his mother, and losing it would bring disaster. Desdemona, frightened, says it is not lost and changes the subject back to Cassio. Othello leaves in a rage. Cassio, meanwhile, has found the handkerchief in his room and asks Bianca to copy the embroidery.

Act 4: the trance and the willow song

Iago keeps up the pressure with crude images until Othello falls into a fit. When he recovers, Iago hides him where he can watch Cassio talk. Iago asks Cassio about Bianca, and Cassio laughs. Othello, too far away to hear, thinks Cassio is laughing about Desdemona. Then Bianca arrives and throws the handkerchief back at Cassio, angry that it came from another woman. For Othello, this is proof. He decides to kill his wife. Iago suggests that he strangle her in the bed she has contaminated, and Othello likes the justice of it.

Lodovico arrives from Venice with letters that recall Othello and make Cassio governor of Cyprus. When Desdemona says she is glad for Cassio, Othello strikes her in front of everyone. Lodovico is shocked that this is the noble general the Senate trusted.

Othello questions Emilia, who swears Desdemona is honest. He then treats his wife as a prostitute and his room as a brothel, and calls her a whore. Desdemona, stunned, asks Iago what she has done. Emilia guesses that some villain has slandered her mistress, without knowing she is describing her husband.

Roderigo complains that he has paid Iago and has nothing. Iago persuades him to kill Cassio that night.

Desdemona prepares for bed. She tells Emilia to lay the wedding sheets on the bed and sings the willow song, which her mother's maid sang as she died of a broken heart. The two women talk about whether wives deceive their husbands. Desdemona cannot believe any woman would. Emilia says she would, for the whole world, and argues that if wives fall, it is because husbands are unkind and unfaithful first.

Spoilers: the ending

This section reveals the ending.

In a dark street Roderigo attacks Cassio and fails. Cassio wounds him. Iago, from behind, stabs Cassio in the leg and runs, then comes back as if he were a rescuer. In the confusion he kills Roderigo to silence him. Othello hears Cassio's cries, believes Iago has done his work, and goes to his wife.

Desdemona is asleep. Othello stands over her with a candle and says he must put out the light, and then put out the light of her life. He kisses her and she wakes. He tells her to pray, because he will not kill her soul. She swears she never loved Cassio and begs to live one more night, then one more half hour, then one prayer. He smothers her.

Emilia knocks with news of the street fight. Desdemona revives for a moment. Asked who did this, she says, "Nobody; I myself," and dies, protecting her husband. Othello admits he killed her and says that Iago told him she was false. Emilia does not stay silent. She calls Othello a fool and shouts for help.

Iago arrives with Montano and others. Emilia reveals that she found the handkerchief and gave it to her husband. Othello sees the truth at last. Iago stabs Emilia and runs. She dies beside Desdemona, singing a line of the willow song. Iago is caught. Othello wounds him, and Iago says only that he bleeds and is not killed. When asked why he did it, Iago refuses to speak another word.

Letters in Roderigo's pocket prove the plot. Othello asks the Venetians to tell the story truly: he was one who loved not wisely but too well, and who threw away a pearl richer than all his tribe. He recalls a day in Aleppo when he struck down a Turk who insulted Venice, then stabs himself and dies on the bed with a kiss. Cassio becomes governor, and Lodovico leaves Iago to him for torture.

Four people die: Roderigo, Desdemona, Emilia and Othello. Iago, who caused it all, lives and stays silent.

What the critics say

Critics have long argued about Iago's motive. He gives several: the lost promotion, the rumor about Emilia, envy of Cassio's daily beauty. Samuel Taylor Coleridge called this "the motive-hunting of a motiveless malignity." In 1693 Thomas Rymer mocked the play as a warning to housewives about their linen, because so much turns on a handkerchief. Later readers, such as F. R. Leavis, argued that Othello's noble self-image makes him quick to believe the worst. Modern critics focus on race: Othello is an outsider whom Venice uses and never fully accepts, and the play's language about him reflects the racism of its world. For centuries white actors played him in dark makeup, a practice now rejected.

Who should read it

Read it if you are studying the play or want a clear account of how Iago's plot works scene by scene. It suits anyone interested in jealousy, manipulation and how an outsider's trust can be turned against him.

Question 1 of 5

Why is Iago angry with Othello at the start of the play?

Questions this book answers

What is Othello about?

Othello by William Shakespeare is about a Moorish general in Venice who marries Desdemona, a senator's daughter. His ensign Iago, angry at being passed over for promotion, convinces him that Desdemona is having an affair with his lieutenant, Cassio. Iago uses a lost handkerchief as proof. The play is about jealousy, manipulation, race and trust.

Why does Iago hate Othello?

Iago gives several reasons. Othello promoted Cassio to lieutenant instead of him. He has heard a rumor that Othello slept with his wife, Emilia, and says he will act as if it were true. He also envies Cassio. None of the motives seems enough for what he does, which is why Coleridge called his evil "motiveless malignity."

How does Othello end?

Othello smothers Desdemona in their bed. Emilia then reveals that she gave the handkerchief to Iago, and Othello learns that his wife was innocent. Iago kills Emilia and is captured. Othello asks to be remembered as one who loved not wisely but too well, and stabs himself. Iago refuses to explain.

What is the significance of the handkerchief in Othello?

The handkerchief is Othello's first gift to Desdemona. He says an Egyptian charmer gave it to his mother and that it holds magic. When Desdemona drops it, Emilia gives it to Iago, who leaves it in Cassio's room. Othello sees it in Cassio's hands and takes it as proof of the affair. A small object becomes the only physical evidence.

What is the theme of Othello?

The main themes are jealousy, which grows on very little evidence; the gap between seeming honest and being honest; race and the outsider, since Othello is a Black general in a white city; reputation; and the power of suggestion. Iago succeeds by hinting, never by direct accusation.
