The illustration above is an external conflict. It exhibits the conflict between Brabantio, Desdemona's father and a government official who works for the Duke, and Desdemona, his daughter and the wife of the general of the Venetian army. In the text, it is stated that "Brabantio: She's a good girl, quiet and obedient. She blushes at the slightest thing. And you want me to believe that despite her young age and proper upbringing she fell in love with a man she'd be afraid to look at?" Moreover, "Desdemona: Father, this isn't easy for me. I'm torn. I owe you respect because you gave me life and education. You're the one I have to obey. I'm your daughter. But this man here is my husband now, and I owe him as much as my mother owed you, just as she preferred you to her own father. So I have to give my obedience to the Moor, my husband." There is an external conflict between Desdemona and Brabantio because Desdemona wants to be with Othello, but Brabantio does not approve of him because he is a Moor. Thus, this is a person vs. person conflict.
The illustration above is an internal conflict. It exhibits how Othello is under great stress because he believes that his wife is cheating on him. According to Act 4 Scene 1 of Othello, "Just keep asking Desdemona, and it'll be yours. If it was up to Bianca to get you your job back, you'd have had it already! Cassio: The poor thing! Othello: He's laughing already! Iago: I never knew a woman who loved a man so much. Cassio: The poor thing, I really think she loves me. Othello: Now he denies it a bit, and tries to laugh it of? Do you think you've won? Cassio: Me, marry her? That whore? Please give me a little credit! I'm not that stupid. Ha, ha, ha! Othello: So, so, so, so! The winner's always got the last laugh, hasn't he?" This is an internal conflict because Othello has conflicting emotions about his wife because he thinks that she is cheating on him with his lieutenant, Cassio. He is insecure and thinks that Cassio and his ensign Iago are discussing how he slept with her, when they are discussing a completely topic. Thus, this is a person vs. themselves conflict.
The illustration above is an external conflict. It is a conflict between Othello, the general of the Venetian army, and Desdemona, his wife. Based on Act 4 Scene 1 of Othello, "Othello: Damn it all! Desdemona: Excuse me, my lord? Othello: Are you right in your mind? Desdemona: Is he angry? Lodovico: Maybe the letter upset him. I think they want him to go home and appoint Cassio governor in his place. Desdemona: I'm happy about that. Othello: Oh, are you really! Desdemona: My lord? Othello: I'm glad you're insane enough to admit it in front of me. Desdemona: Why, sweet Othello- Othello: (striking her) You devil! Desdemona: I haven't done anything to deserve this!" Othello believes that Desdemona is cheating on him, so he is lashing out at her. Thus, this is a person vs. person conflict.
