Othello is a tragedy by William Shakespeare, believed to have been written in 1603. It is based on the story Un Capitano Moro by Cinthio, a disciple of Boccaccio, first published in 1565. The story revolves around its two central characters: Othello, a Moorish general in the Venetian army and his 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.
