Shakespeare's Othello is a fascinating and complex tragic play that depicts the marriage, downfall, and ultimate demise of the main character, Othello. Othello, a Moor and a general in the Venetian army, marries a Venetian noblewoman, Desdemona, without the blessing of her family. Iago, the villain of the story, plots with Roderigo to essentially destroy Othello. Iago cites several reasons for his vengeance, including Othello overlooking him for a promotion and giving the position to Michael Cassio instead, and Othello possibly sleeping with Iago's wife, Emilia. Roderigo, who is used by Iago because he is rich, is in love with Desdemona and works with Iago because he is promised that he will win Desdemona if they are able to defeat Othello.
Iago's plans become progressively more manipulative and complex as he preys upon Othello's insecurities and convinces him that his new wife is having an affair with Cassio. In his rage, Othello kills his wife, despite her protestations of her own innocence until the end. Once it is discovered that Desdemona has died, Emilia is killed by her husband when she begins to realize the role he played in Desdemona's death. Othello wounds Iago (who is then taken into custody) before killing himself, thus bringing to an end a life marred by tragedy.
