Originally name of short coat, worn in north It. district of Carmagnola, and imported into Fr. by workmen from that district. The insurgents of Marseilles in 1792 introduced it to Paris, where it became identified with the Revolution. A round dance of the time was given the name, and a song with the refrain, ‘Dansons la Carmagnole, vive le son du canon’, to a very catchy air, became identified with activities during Reign of Terror. Authorship of words and mus. unknown.
