The play is a tragedy, and Shakespeare explicitly presents it as such: its full title is The Tragedy of Othello, the Moor of Venice.
The play follows the classic tragic pattern: Othello begins as a respected and successful general, but Iago's manipulation drives him into destructive jealousy. Believing the false accusation that Desdemona has been unfaithful, Othello murders his innocent wife. The truth is then revealed, Emilia is killed, and Othello, overcome with remorse, takes his own life. These catastrophic events form the tragic climax and resolution of the play.
A central feature of the tragedy is that Othello's own qualities contribute to his downfall. His trusting nature makes him vulnerable to Iago's deception, and his jealousy prevents him from distinguishing appearance from reality. By the end, he recognizes his terrible mistake, describing himself as one who "loved not wisely, but too well" before taking his own life.
The play also explores tragic themes such as jealousy, prejudice, honor, and the gap between appearance and reality. Othello's fall from an admired leader to a man who destroys what he loves gives the story its enduring tragic power.
