It is widely accepted that Othello was adapted from the story Un Capitano Moro (‘A Moorish Captain’) by Giovanni Battista Giraldi, who was a writer and poet nicknamed ‘Cinthio’. A lot of the action of this play takes place outside. We start at night in a Venetian street, not far from the home of nobleman Brabantio and his daughter Desdemona. Iago, an ensign officer to Military General Othello, stands in the middle of a disagreement with Roderigo – a rich gentleman ‘suitor’ in love with Desdemona. The pair both express a frustration and loathing towards Othello. After many years’ service, Iago learns that he has been passed up for promotion in favour of a younger, less experienced Cassio. Roderigo learns that Othello has just eloped with Desdemona. Roderigo questions whose side Iago is on and complains that Iago was supposed to help him win Desdemona’s heart; now they’re married it is too late. They decide to go to her father’s home and call up to his balcony to wake him. He is very displeased to hear of the news that Desdemona has gone and sends his guards out to find Othello. Brabantio becomes an unknowing associate in Iago’s plan to bring down Othello. So as not to blow his cover, Iago returns to Othello’s side behaving as if he were none the wiser.
Meanwhile, Othello receives word from his new lieutenant, Cassio, that he has been summoned by the Duke to help fight a battle against the invading Turkish army, in Cyprus. Brabantio plans to take his men to confront Othello and accuse him of witchcraft at the Duke’s court. However, Brabantio’s intentions are quashed when praise is given to Othello by the Duke for the outstanding general and fighter that he is. Othello takes the opportunity to defend himself with the truth that Desdemona fell for him naturally, after hearing his stories of war and travel, not with witchcraft. Desdemona steps out into the room to support her new husband and confirm to her father that her allegiance is now with Othello.
While Othello is away, news gets out that the Turkish fleet has been wrecked in a storm. Cassio arrives on the island of Cyprus unharmed, followed by Iago and his wife Emilia (maid and friend to Desdemona), Roderigo and Desdemona on the next ship. Othello greets them and they all plan to celebrate victory and Cyprus’s safety that evening. Roderigo continues to complain that there is no chance of breaking up Othello’s marriage, Iago assures his that Desdemona will likely soon get bored and look elsewhere for satisfaction. (This is, of course, entirely false; Desdemona truly loves Othello and wants no other). Iago starts to weave his web of deceit by planting ideas in Rodrigo’s head to use him as his instrument. Roderigo is gullible, unintelligent and blinded by his infatuation, so is easily manipulated.
Iago acts as counsel and friend to Roderigo and advises him that his next big threat in the fight for Desdemona’s heart is Cassio and that he must disgrace him by starting a fight at the evening’s celebrations. Of course, this is for Iago’s own benefit – he wants to see his new superior demoted. Iago addresses the audience with each step of his plan to ruin Othello. At the party, Iago feigns friendship with Cassio and gets him drunk – a man who swore never to drink for fear of what it does to him. Roderigo provokes Cassio and, of course, a fight breaks out. Cassio, usually well behaved, ends up stabbing an intervening governor in a drunken rage and the alarm is raised. When Othello appears from his bedchamber and demands to know what happened, Iago states that he ‘would not wish to get his friend in trouble’ but does, in fact, relay all the details. Cassio, ashamed, is stripped of his new title and expresses his upset to Iago – who, of course, offers his counsel.
He suggests that while Othello is too angry, Cassio may be best appealing to Desdemona to try and get back his position and that Othello may listen if it comes from his wife. Thus, the next step of Iago’s plot begins. In a soliloquy to the audience, he explains his plan to frame Cassio and Desdemona as lovers. A plausible idea, given their sneaking around to discuss Cassio getting his job back. Iago distracts Othello so Cassio can talk to Desdemona. She is sympathetic to his mistake and assures him she will do what she can to help. A planned misunderstanding occurs when Iago leads Othello back to his wife just in time to see Cassio, very embarrassed, skulk away without a word. Iago insinuates that he cannot believe that this strange and shifty behaviour is due to guilt. And so the seed of guilt is planted in Othello’s mind. When Othello becomes increasingly bad tempered and subdued, Iago cements this thought of guilt with a suggestion that Cassio and Desdemona may be having an affair. When Desdemona then tries to state Cassio’s case as promised and pleads for his forgiveness, Othello is angered all the more and is then convinced of her unfaithfulness.
Iago asks his wife Emilia to take one of Desdemona’s embroidered handkerchiefs. She does so, but doesn’t understand why and Iago does not explain. He then proceeds to plant it in Cassio’s room to ‘prove’ their affair. Iago then tells Othello that he has seen Cassio wipe his beard with the same handkerchief that Othello had given Desdemona. Incensed, Othello demands that Desdemona produce the handkerchief. When she can’t find it and continues to plead with Othello for Cassio’s job, he is driven further into madness and jealousy. Meanwhile, Cassio muses over the strange garment found in his room and shows it to his prostitute companion, Bianca.
Iago sets up a meeting for Othello and Cassio. He asks Othello to hide nearby (out of earshot) so Iago can confront Cassio and get information about the ‘affair’. What Othello doesn’t know is that Iago is in fact asking Cassio about his companion Bianca, causing him to laugh aloud and react accordingly, confirming Othello’s suspicions. Shortly after, Desdemona and a nobleman friend of her father’s, Lodovico, enter. He has a letter from Venice calling Othello home after his distracted behaviour had begun to affect his work. Distraught at the news, Othello lashes out and strikes Desdemona before storming out.
That night, Othello confronts Desdemona and calls her a whore. She protests and tries wholeheartedly to argue her innocence, but Othello simply tells her to wait for him in bed, and to make sure she is alone. During this time, Iago takes measures to reassure an unconvinced Roderigo that everything is going to plan and that in order to secure a means to Desdemona, he needs to first kill Cassio and get him out of the equation. What Iago really intends is to get rid of Roderigo by sending him into harm’s way. He vigorously suggests that Roderigo take Cassio by surprise and attack him; however, this backfires and it is Roderigo that gets hurt by Cassio. When everyone enters to see the commotion, Iago pretends to defend Cassio as his ‘friend’ (in Othello’s absence) and finishes Roderigo off.
While this commotion ensues, we see the start of the final scene, in Othello and Desdemona’s bedchamber. As he stands over her, he smothers her. She again, tries one last time to convince him she is innocent but he does not listen and instead steals her last breaths from her. Emilia enters all of a sudden with news of Roderigo’s death and sees Desdemona dying. When questioned, Othello confirms that he has murdered his wife for the infidelity that Iago had brought to his attention. Iago enters soon after with Brabantio’s noblemen and tries to silence Emilia as she realises what Iago has done. Emilia flies into a rage at how stupid and gullible Othello has been and tells him everything she knows about the handkerchief that Iago asked her to steal that was not proof of an affair, but was planted to frame the pair.
Othello is shocked and heartbroken. He tries to attack and kill Iago but is held back. He manages to wound Iago with a dagger and is quickly disarmed. Lodovico explains how Othello must return to Venice to be tried for his wife’s murder. Othello gives one last speech about how he wants to be remembered, then stabs and kills himself with another dagger hidden on his person. The play ends with a sad speech from Lodovico the noble Venetian lord, who regrets that he has the role of bringing this sad news back to Venice. He gives over Desdemona and Othello’s things to nobleman Gratiano (Desdemona’s uncle) and orders that Iago be executed.
