Brabantio
Brabantio is a Venetian senator and the father of Desdemona. He is a proud man who is fiercely protective of his daughter. When he learns that she has eloped with Othello, a Moorish general, he is furious. He denounces Othello as a "barbarous" and "infidel" and demands that he return Desdemona to him.
Brabantio is a complex character. He is a good man who loves his daughter, but he is also quick to anger and can be unreasonable. His reaction to Desdemona's elopement is understandable, but it is also misguided. He does not take the time to get to know Othello and to understand why Desdemona fell in love with him. As a result, he drives Othello away and sets in motion a chain of events that leads to Desdemona's death.
Brabantio is a tragic figure. He is a victim of his own prejudices and his own pride. He is a man who is unable to see the world beyond his own limited perspective. As a result, he destroys the thing he loves most in the world.
