King Lear

When Lear asks each of his daughters to profess their love for him, he is flattered by the false hyperbole of Regan and Goneril. When his youngest daughter Cordelia confesses to love him simply as a daughter should, his pride is dented and he casts her out of his kingdom.

Too late to realise his mistake, and forced from power by his offspring, an increasingly impotent and frail Lear descends into madness.
