Othello was written by William Shakespeare around 1603-1604, based on an Italian short story. It follows the tragic downfall of Othello, a Moorish general in the Venetian army, who is tricked into believing his wife Desdemona has been unfaithful by his ensign Iago. Key themes include dehumanization, internalized oppression, dramatic irony, and the significance of character names. Othello's race is a prominent theme, exploring English stereotypes of Moors and Africans in the early 1600s.
