Othello (The Tragedy of Othello, the Moor of Venice) is a tragedy by William Shakespeare, believed to have been written in 1603. It is based on the 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 ultimately unfaithful ensign, Iago. Given its varied and enduring themes of racism, love, jealousy, betrayal, revenge and repentance, Othello is still often performed in professional and community theatre alike, and has been the source for numerous operatic, film, and literary adaptations.
