Othello is one of the main characters in a play by William Shakespeare called The Tragedy of Othello, the Moor of Venice.

In the play, Othello, a general in the Venetian army who is married to Desdemona, becomes erroneously convinced (through the machinations of his standard-bearer, Iago) that she is being unfaithful to him with his lieutenant, Cassio. Consumed with jealousy, Othello confronts Desdemona with his suspicions, and ends up smothering her to death in her bed.
