King Lear is a tragedy by William Shakespeare. The title character descends into madness after disposing of his estate between two of his three daughters based on their flattery, bringing tragic consequences for all. The play is based on the legend of Leir of Britain, a mythological pre-Roman Celtic king. It has been widely adapted for the stage and motion pictures, and the role of Lear has been coveted and played by many of the world's most accomplished actors. The play was written between 1603 and 1606 and later revised. Shakespeare's earlier version, The True Chronicle of the History of the Life and Death of King Lear and His Three Daughters, was published in quarto in 1608. The Tragedy of King Lear, a more theatrical version, was included in the 1623 First Folio. Modern editors usually conflate the two, though some insist that each version has its individual integrity that should be preserved
