Macbeth is an anomaly among Shakespeare's tragedies in certain critical ways. It is short: more than a thousand lines shorter than Othello and King Lear, and only slightly more than half as long as Hamlet. This brevity has suggested to many critics that the received version is based on a heavily cut source, perhaps a prompt-book for a particular performance.

Macbeth is a tragedy written by William Shakespeare, and is considered one of his darkest and most powerful works. Set in Scotland, the play illustrates the damaging physical and psychological effects of political ambition on those who seek power for its own sake.

William Shakespeare ( 26 April 1564–23 April 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. He is often called England's national poet and the "Bard of Avon". His extant works, including some collaborations, consist of around 38 plays, 154 sonnets, two long narrative poems, and a few other verses, of which the authorship of some is uncertain. His plays have been translated into every major living language and are performed more often than those of any other playwright.
