Act 5 of William Shakespeare's play "Othello" is the final act and resolves the conflicts that have been building up throughout the play. The act begins with Roderigo confronting Iago, who has been manipulating him throughout the play. Roderigo is angry that he has not been able to win over Desdemona's love and blames Iago for it. Iago stabs Roderigo and leaves him for dead, and then proceeds to carry out his final plan.
Othello enters the scene, having decided to kill Desdemona after being convinced by Iago that she has been unfaithful. Desdemona pleads with Othello to spare her life, insisting that she has been faithful to him. Othello strangles her to death. Emilia, Iago's wife and Desdemona's maid, arrives and discovers what has happened. She confronts Othello, but he insists that he has done the right thing.
Iago enters and kills Emilia, revealing that he had been the one to plant the handkerchief that Othello believed was proof of Desdemona's infidelity. Lodovico, a Venetian nobleman, arrives with Cassio and several soldiers, and Iago's treachery is exposed. Othello, realizing that he has been tricked, stabs himself and dies. Cassio is appointed as the new governor of Cyprus, and Lodovico orders that Iago be taken away to be punished for his crimes.
In the final moments of the play, Lodovico delivers a speech condemning the tragic events that have transpired, lamenting the loss of Desdemona and the downfall of Othello. The play ends with Lodovico's line, "O Spartan dog, more fell than anguish, hunger, or the sea, look on the tragic loading of this bed. This is thy work."
