This is what we found on Wikipedia regarding the Macbeth:

The Tragedy of Macbeth, often shortened to Macbeth (), is a tragedy by William Shakespeare, estimated to have been first performed in 1606. It dramatises the physically violent and damaging psychological effects of political ambitions and power. It was first published in the Folio of 1623, possibly from a prompt book, and is Shakespeare's shortest tragedy. Scholars believe Macbeth, of all the plays that Shakespeare wrote during the reign of King James I, contains the most allusions to James, patron of Shakespeare's acting company.

In the play, a brave Scottish general named Macbeth receives a prophecy from a trio of witches that one day he will become King of Scotland. Consumed by ambition and spurred to violence by his wife, Macbeth murders the king and takes the Scottish throne for himself. Then, racked with guilt and paranoia, he commits further violent murders to protect himself from enmity and suspicion, soon becoming a tyrannical ruler. The bloodbath swiftly leads to insanity and finally death for the powerhungry couple.

Shakespeare's source for the story is the account of Macbeth, King of Scotland, Macduff, and Duncan in Holinshed's Chronicles (1587), a history of England, Scotland, and Ireland familiar to Shakespeare and his contemporaries, although the events in the play differ extensively from the history of the real Macbeth. The events of the tragedy have been associated with the execution of Henry Garnet for complicity in the Gunpowder Plot of 1605.

In the backstage world of theatre, some believe that the play is cursed and will not mention its title aloud, referring to it instead as "The Scottish Play". The play has attracted some of the most renowned actors to the roles of Macbeth and Lady Macbeth and has been adapted to film, television, opera, novels, comics, and other media.
