Macbeth

Background
Macbeth (full title The Tragedy of Macbeth) is a tragedy by William Shakespeare, which dramatises the damaging physical and psychological effects of political ambition on those who seek power for its own sake. Of all the plays that Shakespeare wrote during the reign of James I, who was patron of Shakespeare's acting company, Macbeth most clearly reflects the playwright's relationship with his sovereign. It was first published in the Folio of 1623, possibly from a prompt book, and is Shakespeare's shortest tragedy.

Summary
Macbeth, a Scottish noble, is urged by his wife to kill King Duncan to take the throne for himself. He covers the king's guards in blood to frame them for the deed, and is appointed King of Scotland. However, people suspect his sudden power, and he finds it necessary to commit more and more murders to maintain power, believing himself invincible so long as he is bloody. Finally, the old king's son Malcolm besieges Macbeth's castle, and Macduff slays Macbeth in armed combat.
