Othello (The Tragedy of Othello, the Moor of Venice) is a tragedy by William Shakespeare, believed to have been written in the year 1603, and based on the short story Un Capitano Moro ("A Moorish Captain") by Cinthio, a disciple of Boccaccio, first published in 1565. This tightly constructed work revolves around four central characters: Othello, a Moorish general in the Venetian army; his beloved wife, Desdemona; his loyal lieutenant, Cassio; and his trusted but unfaithful ensign, Iago. The play opens with Roderigo, a rich and dissolute gentleman, complaining to Iago, an ensign, that Iago has not told him about the secret marriage between Desdemona, the daughter of a Senator named Brabantio, and Othello, a Moorish general in the Venetian army. He is upset by this development because he loves Desdemona and had asked her father for her hand in marriage. Iago hates Othello for promoting a younger man named Michael Cassio above him, and tells Roderigo that he plans to use Othello for his own advantage. Iago is also angry because he believes, or at least gives the pretence of belief, that Othello slept with his wife Emilia. Iago denounces Cassio as a scholarly tactician with no real battle experience; in contrast, Iago is a battle-tested soldier. By emphasising Roderigo's failed bid for Desdemona, and his own dissatisfaction with serving under Othello, Iago convinces Roderigo to wake Brabantio, Desdemona's father, and tell him about his daughter's elopement. Iago sneaks away to find Othello and warns him that Brabantio is coming for him. Because of its varied and current themes of racism, love, jealousy, betrayal, revenge and repentance, Othello is still often performed in professional and community theatre alike and has been the basis for numerous operatic, film, and literary adaptations.
