Macbeth (play), tragedy in five acts, written by English playwright and poet William Shakespeare. First performed in about 1606, the play was originally printed in the 1623 edition of Shakespeare's works known as the First Folio. The author’s principal source for Macbeth was Chronicles of England, Scotland, and Ireland (1577) by English chronicler Raphael Holinshed. The play’s title role is loosely based on the career of a King Macbeth of Scotland. A commander under King Duncan I, Macbeth murdered Duncan in 1040 and claimed the kingdom for himself. After a rule of 17 years, Macbeth was killed by Duncan’s son Malcolm, who later became King Malcolm III.
