Othello," a tragedy written by William Shakespeare, remains a powerful exploration of jealousy, betrayal, and the destructive power of suspicion. The play is set in motion when Othello, a heroic black general in the service of Venice, appoints Cassio and not Iago as his chief lieutenant. Jealous of Othello’s success and envious of Cassio, Iago plots Othello’s downfall by falsely implicating Othello’s wife, Desdemona, and Cassio in a love affair. With the unwitting aid of Emilia, his wife, and the willing help of Roderigo, a fellow malcontent, Iago carries out his plan.
