Othello is one of Shakespeare's tragedies written around 1604 and thought to be based on an Italian story. It is set in Venice and Cyprus, though Shakespeare never visited these places. The play explores themes of racial tensions, as Othello is a Moorish general in the Venetian army who secretly marries the daughter of a senator. His ensign Iago hatches a plot to convince Othello that his wife Desdemona has been unfaithful by manipulating Othello's jealousy and rage. Iago's deception destroys Othello and Desdemona's marriage and ultimately leads to tragedy.
