"King Lear" is a tragedy written by William Shakespeare. It is based on the mythological Leir of Britain. Lear, the elderly king of England decides to retire and divide his kingdom evenly between his three daughters: Regan, Goneril and Cordelia.

Before dividing his kingdom, Lear asks each of his daughters to demonstrate the extent of their love for him. Much to his delight, Lear's eldest daughters, Regan and Goneril, offer over-the-top assertions of their love. However, Lear's youngest and more beloved daughter, Cordelia, remains silent. Cordelia's response sends King Lear into a fit of rage, and he exiles her from his kingdom. Cordelia accepts an offer of marriage from the King of France and leaves.

After Lear is rejected by Cordelia's sisters, Goneril and Regan, he goes mad. Cordelia returns at the end of the play with the intentions of helping Lear, ultimately reversing her role as daughter to that of mother.
