Othello (The Tragedy of Othello, the Moor of Venice) is a tragedy by William Shakespeare, believed to have been written in 1603.

It is based on the story Un Capitano Moro ("A Moorish Captain") by Cinthio, a disciple of Boccaccio, first published in 1565. This tightly constructed work revolves around four central characters: Othello, a Moorish general in the Venetian army; his beloved wife, Desdemona; his loyal lieutenant, Cassio; and his trusted but ultimately unfaithful ensign, Iago.

Given its varied and enduring themes of racism, love, jealousy, betrayal, revenge and repentance, Othello is still often performed in professional and community theatre alike, and has been the source for numerous operatic, film, and literary adaptations.

William Shakespeare (1564-1616) was an English poet, playwright and actor, widely regarded as the greatest writer in the English language and the world's pre-eminent dramatist. His extant works, including some collaborations, consist of about 38 plays, 154 sonnets, two long narrative poems, and a few other verses. His plays have been translated into every major living language and are performed more often than those of any other playwright.

Shakespeare was a respected poet and playwright in his own day, but his reputation did not rise to its present heights until the 19th century. His plays remain highly popular today and are constantly studied, performed, and reinterpreted in diverse cultural and political contexts throughout the world.

In 2016, celebrations will commence in the United Kingdom and across the world to honour The Bard's 400th anniversary.
