Shakespeare's classic tragedy
Story:
Iago is furious about being overlooked for promotion and plots to take revenge against his General: Othello, the Moor of Venice. Iago manipulates Othello into believing his wife Desdemona is unfaithful, stirring Othello's jealousy. Othello allows jealousy to consume him, murders Desdemona, and then kills himself.
Fun Fact
Shakespeare's primary source for the plot was the story of a Moorish Captain (third decade, story seven) in Gli Hecatommithi by Cinthio (Giovanni Battista Giraldi), a collection of one hundred novellas about love, grouped into ten "decades" by theme.
