After the Restoration, the play was often revised with a happy ending for audiences who disliked its dark and depressing tone, but since the 19th century Shakespeare's original version has been regarded as one of his supreme achievements. The tragedy is particularly noted for its probing observations on the nature of human suffering and kinship. George Bernard Shaw wrote, "No man will ever write a better tragedy than Lear".

King Lear is a tragedy by William Shakespeare in which the titular character descends into madness after disposing of his estate between two of his three daughters based on their flattery, bringing tragic consequences for all. Based on the legend of Leir of Britain, a mythological pre-Roman Celtic king, the play has been widely adapted for the stage and motion pictures, with the title role coveted by many of the world's most accomplished actors.

William Shakespeare ( 26 April 1564—23 April 1616) was an English poet, playwright, and actor, widely regarded as the greatest writer in the English language and the world's pre-eminent dramatist. He is often called England's national poet and the "Bard of Avon". His extant works, including some collaborations, consist of around 38 plays, 154 sonnets, two long narrative poems, and a few other verses, of which the authorship of some is uncertain. His plays have been translated into every major living language and are performed more often than those of any other playwright.
