Macbeth is a play written by William Shakespeare. It is considered one of his darkest and most powerful tragedies. Set in Scotland, the play dramatizes the corroding psychological and political effects produced when its protagonist, the Scottish lord Macbeth, chooses evil as the way to fulfill his ambition for power. He commits regicide to become king and then furthers his moral descent with a reign of murderous terror to stay in power, eventually plunging the country into civil war. In the end, he loses everything that gives meaning and purpose to his life before losing his life itself. (Summary by Wikipedia)
