Othello, a soldier accustomed to routines and regimented practices, imposes a similar dictation on his married life. Although he is happy to fight and lead his people, being with his wife is where he feels happiest. The combination of being a soldier and being in love was closely intertwined in Othello's life, and once he began to become less involved in the military, he began to feel less confident in his relationship with Desdemona. Once he discovered this weakness in Othello, Iago planned an epic revenge by spreading lies about Desdemona's infidelity. After Iago repeatedly presents false evidence that Desdemona was having an affair, Othello begins to go completely insane. In his madness, Othello confronts Desdemona about what happened between her and Cassio. Othello uses the “proof” that Iago gave him, the handkerchief he once gave him, as a token of his love. Iago told him that Desdemona had given it to Cassio as a sign of her new love. She denies any accusations regarding this, as she was not really guilty of these actions. Even though Desdemona continues to declare that she would never do something like that to him, Othello is still mad with jealousy and can no longer stand what he thought were her lies and chokes her to death. Shortly after, Emilia enters the room and demands to know what happened.
