He is the husband of Emilia, who is in turn the attendant of Othello's wife Desdemona. Iago hates Othello and devises a plan to destroy him by making him believe that his wife is having an affair with his lieutenant, Michael Cassio.
Desdemona is killed by Othello, Iago kills Emilia (his wife) as Emilia reveals that Desdemona has been falsely accused of adultery and then Othello kills himself rather than live with what he has done.
