Britannica: Macbeth"The tragedy of Macbeth, a play in five acts by William Shakespeare, portrays the rise and fall of a Scottish nobleman whose blind ambition leads him to commit several murders in order to become king. While Macbeth’s monstrous acts evoke horror, his self-awareness, inner struggle, and haunted spirit elicit some sympathy. The play was written sometime in 1606–07 and first published in 1623, in the First Folio edition of Shakespeare’s plays. The character Macbeth was loosely based on a real Scottish king of that name, who ruled in the 11th century. Macbeth is the shortest of Shakespeare’s tragedies, without diversions or subplots."
