iam Shakespeare. Set mainly in Scotland, the play dramatises the damaging physical and psychological effects of political ambition on those who seek power for its own sake. The play is believed to have been written between 1599 and 1606. The earliest account of a performance of what was probably Shakespeare's play is April 1611, when Simon Forman recorded seeing such a play at the Globe Theatre. It was first published in the Folio of 1623, possibly from a prompt book. It was most likely written during the reign of James I (of England), who had already been crowned James VI of Scotland before he succeeded to the English throne as well in 1603. James VI/I was a patron of Shakespeare's acting company, and of all the plays Shakespeare wrote during James's reign, Macbeth most clearly reflects the playwright's relationship with the sovereign. Macbeth is Shakespeare's shortest tragedy, and tells the story of a brave Scottish general named Macbeth who receives a prophecy from a trio of witches that one day he will become King of Scotland. Consumed by ambition and spurred to action by his wife, Macbeth murders King Duncan and takes the Scottish throne for himself. He is then wracked with guilt and paranoia, and he soon becomes a tyrannical ruler as he is forced to commit more and more murders to protect himself from enmity and suspicion. The bloodbath and consequent civil war swiftly take Macbeth and Lady Macbeth into the realms of madness, and death.
