Shakespearean tragedies --- Othello

Main character, "Cassio is extremely ashamed after being implicated in a drunken brawl on Cyprus and losing his place as lieutenant......(Othello)"

Can I say a drunken behaviour as one behaved him/herself unusual after drunk alcohol?


Synopsis
The play opens with Roderigo, a rich and foolish gentleman, complaining to Iago, a high-ranking soldier, that Iago didn't tell him about the secret marriage between Desdemona, daughter of a Senator named Brabantio, and Othello, a black general of the Venetian army. He is upset by this development because he loves Desdemona and has previously asked her father for her hand in marriage. Iago is upset with Othello for promoting a younger man named Cassio above him, and tells Roderigo that he is simply using Othello for his own advantage. Iago's argument against Cassio is that he is a scholarly tactician and has no real battle experience from which he can draw. By emphasizing this point, and his dissatisfaction with serving under Othello, Iago convinces Roderigo to wake Brabantio and tell him about his daughter's marriage. After Roderigo rouses Brabantio, Iago makes an aside that he has heard rumors that Othello has had an affair with his wife, Emilia. This acts as the second explicit motive for Iago's actions. Later, Iago tells Othello that he overheard Roderigo telling Brabantio about the marriage and that he (Iago) was angry because the development was meant to be secret. This is the first instance we see Iago blatantly lie within the text.

News arrives in the Senate that the Turks have attacked Cyprus and Othello is summoned to advise. Brabantio arrives and accuses Othello of seducing Desdemona by witchcraft, but Othello defends himself successfully before an assembled Senate.
By order of the Duke, Othello leaves Venice to command the Venetian armies against invading Turks on the island of Cyprus, accompanied by his new wife, his new lieutenant Cassio, his ensign Iago and Emilia, Iago's wife, who works as a maid to Desdemona. When they arrive, they find that a storm has destroyed the Turkish fleet, and all break out in celebration.

Iago, who resents Othello for favoring Cassio, takes the opportunity of Othello being away from home to manipulate his superiors and make Othello think that his wife has been unfaithful. He persuades Roderigo to engage Cassio in a fight, then gets Cassio drunk. When Othello discovers Cassio drunk and in a fight, he strips him of his ranks, and confers them upon Iago, which in turn strips Iago of his two stated reasons to exact revenge on Othello. After Cassio sobers up a bit, Iago persuades Cassio to try Desdemona as an intermediary on Othello. It is of some note that throughout the text, Othello and other characters refer to Iago as "good" and "honest."

Iago now works on Othello to make him suspicious of Desdemona and Cassio. As it happens, Cassio is seeing a woman named Bianca. Desdemona drops a handkerchief that was Othello's first gift to her and which he has stated holds great significance to him in the context of their relationship. Emilia obtains this for Iago, who has asked her to steal it, having decided to plant it in Cassio's lodgings as evidence of Cassio and Desdemona's affair. Emilia is unaware of what Iago plans to do with the handkerchief. After he has planted the handkerchief, Iago tells Othello to hide, and goads Cassio on to talk about his affair with his mistress Bianca, but since Bianca's name is not mentioned Othello thinks that Cassio is referring to Desdemona. Bianca, on discovering the handkerchief, leaves Cassio. Enraged and hurt, Othello decides to kill his wife and orders Iago to kill Cassio.

Iago convinces a sexually-frustrated Roderigo to kill Cassio because Cassio has just been appointed in Othello's place and, if Cassio lives to take office, Othello and Desdemona will leave Cyprus, thwarting Roderigo's plans to win Desdemona. Roderigo attacks Cassio in the street after Cassio leaves Bianca's lodgings and they fight. Both are wounded. Passers-by arrive to help and Iago joins them, pretending to help Cassio. Iago secretly stabs Roderigo to stop him talking and accuses Bianca of conspiracy to kill Cassio.

In the night, Othello confronts Desdemona, and then kills her, smothering her in bed out of intense jealousy, before Iago's wife, Emilia, arrives. At Emilia's distress Othello tries to explain himself, justifying his actions by way of her affair, citing the handkerchief (distinctively embroidered) as proof. Emilia realizes what Iago has done, and she reveals that Desdemona's "affair" was Iago's invention, and that Iago is anything but honest. Determined to have Othello arrested for murdering the innocent Desdemona, Emilia calls for the guard. They arrive, and Emilia begins to explain the situation. Iago kills Emilia; Othello, realizing he has been toyed with, attacks Iago but is disarmed. Lodovico, a Venetian nobleman, apprehends both Iago and Othello, but Othello commits suicide with a dagger, holding his wife's body in his arms, before they can take him into custody. At the end, it can be assumed, Iago is taken off to be tortured and possibly executed.
