Along with Hamlet, King Lear, and Macbeth, Othello is one of Shakespeare's four great tragedies and thus a pillar of what most critics take to be the apex of Shakespeare's dramatic art. Othello is unique among Shakespeare's great tragedies. Unlike Hamlet, King Lear, and Macbeth, which are set against a backdrop of affairs of state and which reverberate with suggestions of universal human concerns, Othello is set in a private world and focuses on the passions and personal lives of its major figures. Indeed, it has often been described as a "tragedy of character"; Othello's swift descent into jealousy and rage and Iago's dazzling display of villainy have long fascinated students and critics of the play. The relationship between these characters is another unusual feature of Othello. With two such prominent characters so closely associated, determining which is the central figure in the play and which bears the greater responsibility for the tragedy is difficult.

More than anything else, what distinguishes Othello from its great tragedies' peers is the role of its villain, Iago. While the usurper King Claudius of Hamlet, the faithless daughters of Lear, and the unnatural villains of Macbeth (Macbeth, his Lady and the Weird Sister witches) are all impressively evil in their own way, none of them enjoys the same diabolical role as Iago.

Iago is a character who essentially writes the play's main plot, takes a key part in it, and gives first-hand direction to the others, most notably to the noble Moor, Othello. The play presents us with two remarkable characters, Iago and his victim, with Iago as the dominant force that causes Othello to see the infidelity of his young and beautiful wife, Desdemona, with his favorite lieutenant, Michael Cassio. Indeed, not only is "seeing" and the gap between appearance and reality a central theme of the play, it overlaps with other major thematic strands (trust, honor, and reputation) and sheds light on still others, including the theme of patriarchy and the political state.

Written in 1604, Othello is one of Shakespeare's most highly concentrated, tightly constructed tragedies, with no subplots and little humor to relieve the tension. Although he adapted the plot of his play from the sixteenth-century Italian dramatist and novelist Giraldi Cinthio's Gli Hecatommithi, Shakespeare related almost every incident directly to the development of Iago's schemes and Othello's escalating fears. This structure heightens the tragedy's ominous mood and makes the threat to both Desdemona's innocence and the love she and Othello share more terrifying.

Although narrow in scope, Othello, with its intimate domestic setting, is widely regarded as the most moving and the most painful of Shakespeare's great tragedies. The fall of a proud, dignified man, the murder of a graceful, loving woman, and the unreasoning hatred of a "motiveless" villain—all have evoked fear and pity in audiences throughout the centuries. If it lacks the cosmic grandeur of Hamlet or King Lear, Othello nevertheless possesses a power that is perhaps more immediate and strongly felt for operating on the personal, human plane.

Othello Synopsis

Summary of the Play

On a quiet night in Venice, Iago, ensign to the Moorish general, Othello, enlists the aid of Roderigo in his plot against Othello. Iago secretly hates Othello and tells Roderigo, a rejected suitor to Desdemona, that she has eloped with the Moor. After this revelation, Roderigo and Iago awaken Brabantio, Desdemona’s father, with news that she has been transported into Othello’s hands. Iago informs Othello of Brabantio’s anger. Brabantio arrives with officers to confront Othello, but they are interrupted by Michael Cassio, who summons Othello to the Duke of Venice’s palace.

The duke and senators welcome Othello and inform him of his deployment to Cyprus in a defensive against the Ottomites. Brabantio accuses Othello of winning Desdemona’s affection by magic, after which Othello explains that he won Desdemona’s love by sincere means. Desdemona professes her duty to her husband. Subsequently, Othello is sent to Cyprus, leaving Iago in charge of Desdemona’s safe passage to Cyprus along with Emilia, Iago’s wife and Desdemona’s attendant. Iago suggests that Roderigo follow Desdemona to Cyprus. Once alone, Iago reveals his plan to implicate Michael Cassio in a clandestine affair with Desdemona.

During a raging storm which destroys the Turkish fleet, Othello and his men land at the Cyprian seaport. By telling Roderigo a lie that Desdemona loves Cassio, Iago now urges Roderigo to incite Cassio to violence. Later that evening at Othello’s wedding feast, Iago gets Cassio drunk; as a result, Othello dismisses Cassio from service because of behavior unbecoming a lieutenant. Iago then encourages Cassio to appeal to Desdemona to influence Othello to reinstate Cassio.

Desdemona tells Cassio that she will help him. Cassio leaves quickly, and when Othello arrives, Desdemona pleads for Cassio. Iago uses Cassio’s quick exit and Desdemona’s pleas to cast doubt on her fidelity and Cassio’s integrity.

Desdemona and Emilia enter, and Othello admits to a headache. When Desdemona tries to assuage his illness with her handkerchief, he knocks it down. Emilia picks it up and gives it to Iago. When Othello demands visible proof of Desdemona’s infidelity, Iago asserts that he has seen Cassio with the handkerchief. Having become sufficiently suspicious, Othello vows revenge. Later, Cassio gives the handkerchief that Iago hid in Cassio’s room to Bianca, his jealous mistress, in order for her to copy.

Riled by Iago’s lies and innuendos, Othello succumbs to a trance. After he revives, Iago incites him anew by talking to Cassio about Bianca while Othello eavesdrops on the conversation. Mistakenly, Othello thinks Cassio is boasting about having seduced Desdemona. Bianca enters and throws the handkerchief at Cassio; consequently, Othello, convinced of Desdemona’s guilt, swears to kill her.

Lodovico, Brabantio’s kinsman, arrives with orders from the duke for Othello to return to Venice, leaving Cassio in charge in Cyprus for which Desdemona expresses pleasure. Othello strikes her, and his actions give Iago cause to suggest that Othello is going mad. Iago then convinces Roderigo that killing Cassio will ensure his chances with Desdemona. Later in the evening, Othello orders Desdemona to wait for him alone in their bed chamber. As she prepares to retire, she sings a song about forsaken love.

At Iago’s instigation, Roderigo attacks Cassio, who in turn wounds Roderigo. Iago then stabs Cassio so that Othello thinks Iago has kept a promise to kill Cassio. When Roderigo cries out, Iago kills him.

In the bed chamber, while Othello ponders Desdemona’s beauty and innocence, she awakens, and Othello commands her to pray before she dies. In spite of her supplications, he suffocates her with a pillow. Emilia enters, and Othello justifies his revenge by claiming the handkerchief as proof of her infidelity. Appalled at this act, Emilia reveals Iago’s guilt. Iago enters, kills Emilia, and is arrested. Othello tries to kill Iago, and despite demands for an explanation, Iago remains silent and is led off. Before Othello is led off, he draws a concealed weapon, stabs himself, and kisses Desdemona as he dies.

Estimated Reading Time
An average student should plan to spend at least one hour to read each act of the play for the first reading if the text used provides sufficient footnotes. Subsequent readings will take less time as familiarity with the vocabulary, the story line, and the writer’s style increases. Othello comprises five acts with a total of 15 scenes; consequently, the student might feel comfortable reading three to five scenes at each session, which would entail a total reading time of three to five hours.

Othello Summary

(Critical Survey of Literature for Students)

Iago, an ensign serving under Othello, Moorish commander of the armed forces of Venice, is passed over in promotion when Othello chooses Cassio to be his chief of staff. In revenge, Iago and his follower, Roderigo, arouse from his sleep Brabantio, senator of Venice, to tell him that his daughter, Desdemona, has stolen away and married Othello. Brabantio, incensed that his daughter would marry a Moor, leads his servants to Othello’s quarters.

Meanwhile, the duke of Venice has learned that armed Turkish galleys are preparing to attack the island of Cyprus, and in this emergency he has summoned Othello to the senate chambers. Brabantio and Othello meet in the streets but postpone any violence in the national interest. Othello, upon arriving at the senate, is commanded by the duke to lead the Venetian forces to Cyprus. Then, Brabantio tells the duke that Othello has beguiled his daughter into marriage without her father’s consent. When Brabantio asks the duke for redress, Othello vigorously defends his honor and reputation; he is seconded by Desdemona, who appears during the proceedings. Othello, cleared of all suspicion, prepares to sail for Cyprus immediately. For the time being, he places Desdemona in the care of Iago; Iago’s wife, Emilia, is to be her attendant during the voyage to Cyprus.

A great storm destroys the Turkish fleet and scatters the Venetians. One by one, the ships under Othello’s command head for Cyprus until all are safely ashore and Othello and Desdemona are once again united. Still intent on revenge, Iago tells Roderigo that Desdemona is in love with Cassio. Roderigo, himself in love with Desdemona, is promised all of his desires by Iago if he will engage Cassio, who does not know him, in a personal brawl while Cassio is officer of the guard.

Othello declares the night dedicated to celebrating the destruction of the enemy, but he cautions Cassio to keep a careful watch on Venetian troops in the city. Iago talks Cassio into drinking too much, so that when provoked by Roderigo, Cassio loses control of himself and fights with Roderigo. Cries of riot and mutiny spread through the streets. Othello, aroused by the commotion, demotes Cassio for permitting a fight to start. Cassio, his reputation all but ruined, welcomes Iago’s promise to secure Desdemona’s goodwill and through her have Othello restore Cassio’s rank.

Cassio importunes Iago to arrange a meeting between him and Desdemona. While Cassio and Desdemona are talking, Iago entices Othello into view of the pair, and speaks vague innuendoes. Afterward, Iago from time to time asks Othello questions in such a manner as to lead Othello to think there might have been something between Cassio and Desdemona before Desdemona married him. Once Iago has sown these seeds of jealousy, Othello begins to doubt his wife.

When Othello complains to Desdemona of a headache, she offers to bind his head with the handkerchief that had been Othello’s first gift to her. She drops the handkerchief inadvertently, and Emilia picks it up. Iago, seeing an opportunity to further his scheme, takes the handkerchief from his wife and hides it in Cassio’s room. When Othello asks Iago for proof that Desdemona is untrue to him, threatening his life if he cannot produce any evidence, Iago says that he had slept in Cassio’s room and had heard Cassio speak sweet words in his sleep to Desdemona. He reminds Othello of the handkerchief and says that he had seen Cassio wipe his beard that day with that very handkerchief. Othello, completely overcome by passion, vows revenge. He orders Iago to kill Cassio, and he appoints the ensign his new lieutenant.

Othello asks Desdemona to account for the loss of the handkerchief, but she is unable to explain its disappearance. She is mystified by Othello’s shortness of speech, and his dark moods. Goaded by Iago’s continuing innuendoes, the Moor succumbs to mad rages of jealousy in which he falls into fits resembling epilepsy. In the presence of an envoy from Venice, Othello strikes Desdemona, to the consternation of all. Emilia swears that her mistress is honest and true, but Othello, who in his madness can no longer believe anything good of Desdemona, reviles and insults her with harsh words.

One night, Othello orders Desdemona to dismiss her attendant and to go to bed immediately. That same night Iago persuades Roderigo to waylay Cassio. When Roderigo is wounded by Cassio, Iago, who had been standing nearby, stabs Cassio. In the scuffle Iago stabs Roderigo to death as well, so as to be rid of his dupe, who might talk. Then a strumpet friend of Cassio comes upon the scene of the killing and reveals to the assembled crowd her relationship with Cassio. Although Cassio is not dead, Iago hopes to use this woman to defame Cassio beyond all hope of regaining his former reputation. Pretending friendship, he assists the wounded Cassio back to Othello’s house. They are accompanied by Venetian noblemen who had gathered after the fight.

Othello enters his wife’s bedchamber and smothers her, after telling her, mistakenly, that Cassio has confessed his love for her and has been killed. Then Emilia enters the bedchamber and reports that Roderigo has been killed, but not Cassio. This information makes doubly bitter for Othello his murder of his wife. Othello tells Emilia that he learned of Desdemona’s guilt from Iago. Emilia cannot believe that Iago had made such charges.

When Iago and other Venetians arrive at Othello’s house, Emilia asks Iago to refute Othello’s statement. Then the great wickedness of Iago comes to light, and Othello learns how the handkerchief had come into Cassio’s possession. When Emilia gives further proof of her husband’s villainy, Iago stabs her. Othello lunges at Iago and manages to wound him before the Venetian gentlemen could seize the Moor. Emilia dies, still protesting the innocence of Desdemona. Mad with grief, Othello plunges a dagger into his own heart. The Venetian envoy promises that Iago will be tortured to death at the hands of the governor general of Cyprus.
