A dandy is a man who places particular importance upon physical appearance and personal grooming, refined language and leisurely hobbies. A dandy could be a self-made man both in person and persona, who emulated the aristocratic style of life regardless of his middle-class origin, birth, and background, especially during the late 18th and early 19th centuries in Britain.
Early manifestations of dandyism were Le petit-maître (the Little Master) and the musk-wearing Muscadin ruffians of the middle-class Thermidorean reaction (1794–1795). Modern dandyism, however, emerged in stratified societies of Europe during the 1790s revolution periods, especially in London and Paris. Within social settings, the dandy cultivated a persona characterized by extreme posed cynicism, or "intellectual dandyism" as defined by Victorian novelist George Meredith; whereas Thomas Carlyle, in his novel Sartor Resartus (1831), dismissed the dandy as "a clothes-wearing man"; Honoré de Balzac's La fille aux yeux d'or (1835) chronicled the idle life of a model French dandy whose downfall stemmed from his obsessive Romanticism in the pursuit of love, which led him to yield to sexual passion and murderous jealousy.
