King Lear tells the tale of the aged King Lear who is passing on the control of his kingdom to his three daughters. He asks each of them to express their love for him, and the first two, Goneril and Regan do so effusively, saying they love him above all things. But his youngest daughter, Cordelia, is compelled to be truthful and says that she must reserve some love for her future husband. Lear, enraged, cuts her off without any inheritance.

The secondary plot deals with the machinations of Edmund, the bastard son of the Earl of Gloucester, who manages to convince his father that his legitimate son Edgar is plotting against him.

After Lear steps down from power, he finds that his elder daughters have no real respect or love for him, and treat him and his followers as a nuisance. They allow the raging Lear to wander out into a storm, hoping to be rid of him, and conspire with Edmund to overthrow the Earl of Gloucester.

The play is a moving study of the perils of old age and the true meaning of filial love. It ends tragically with the deaths of both Cordelia and Lear—so tragically, in fact, that performances during the Restoration period sometimes substituted a happy ending. In modern times, though, King Lear is performed as written and generally regarded as one of Shakespeare’s best plays.
