Othello
Othello, a General employed by the Venetian state, has secretly married Desdemona, a daughter of the Venetian senator Brabantio. Iago, an ensign nursing a private grudge against Othello, sets about revenging himself. He and Roderigo, a disappointed suitor of Desdemona, bring Brabantio to the Senate where, learning that she has married Othello of her own accord, he disowns his daughter. Othello is immediately ordered to the Venetian colony of Cyprus to repel a threatened Turkish invasion. Desdemona sails with her husband, taking with them her companion Emilia, who is also Iago's wife, and Othello's lieutenant Michael Cassio, newly promoted over Iago's head.
Once in Cyprus, Iago plants the suspicion in Othello's mind that Desdemona has been unfaithful to him with Cassio. He engineers a drunken brawl for which Cassio is blamed and dismissed by Othello. Desdemona intercedes on Cassio's behalf but her constant pleas to Othello for his reinstatement only serve to convince Othello that Cassio is her lover. Iago acquires a treasured handkerchief from Desdemona and uses it as 'proof' of the affair. Increasingly maddened by jealousy, Othello orders Iago to kill Cassio and strangles Desdemona himself.
Emilia discloses her husband's plot and Othello, tormented by grief and remorse, kills himself. Iago, after murdering his own wife, is left to the justice of the Venetian state.
