The Tragedy of Othello, the Moor of Venice is a tragedy by William Shakespeare, believed to have been written in approximately 1603, and based on the Italian short story Un Capitano Moro ("A Moorish Captain") by Cinthio, a disciple of Boccaccio, first published in 1565. The 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.
