William Shakespeare was born in 1564 and died in 1616. Throughout his life he wrote a number of plays that are very recognizable to this day. His most famous, although very controversial, play was the tragedy titled Othello. Othello, up to this date, is the most consistently popular and performed play Shakespeare had written. The play was set in Italy, closest to the Middle East. In Shakespeare's Othello, Iago drove Othello to insanity by putting thoughts of Desdemona committing adultery in his mind. However, the couple should not have given into Iago's trickery.
There are many points in this tragedy that make the reader think the couple should have known what Iago was trying to do. The first point that comes to mind is time. The play opens with Roderigo and Iago at the home of Senator Brabantio. They scream to the Senator that a Moor had stolen his daughter, and slept with her. This is when the reader first realizes Roderigo and especially Iago were out to ruin Othello's life. Outraged Brabantio calls for his men to retrieve the Moor, or better known as Othello. Othello then confesses his love for the Senator's daughter Desdemona, and orders Brabantio to send for his daughter so she could prove their love. Prove it she did; she told her father that they were madly in love, and that they exchanged wedding vows. Right after this confession took place Othello had to be sent to war and he begged the Duke to have Desdemona be sent after him. After they returned they finally had their wedding night together. Iago's plan began with having Cassio, Othello's officer get drunk; after getting completely intoxicated he gets in a "planned" fight with Roderigo. Bells rang and Othello sees what Cassio had done and tells him he will never be an officer to him again. .
This leaves the door wide open for Iago to get Cassio and Othello against each other. Iago started to hint to Othello that his wife was very young and foolish; a bit of a flirt.
