Democracy: An American Novel is a political novel written by Henry Brooks Adams and published anonymously in 1880. Only after the writer's death in 1918 did his publisher reveal Adams's authorship although, upon publication, the novel had immediately become popular. Contemporaneous conjecture placed the book under the joint authorship of Clarence King, John Hay and Henry Adams and their spouses who lived side by side on H street in Washington, D.C. and were collectively sometimes called "the Five of Hearts."In January 2005, the Washington National Opera premiered Democracy: An American Comedy, an opera by Scott Wheeler and Romulus Linney based upon Henry Adams' book.
