The Quadrille is a dance that was fashionable in late 18th- and 19th-century Europe and its colonies. Performed by four couples in a rectangular formation, it is related to American square dancing. The Lancers, a variant of the quadrille, became popular in the late 19th century and was still danced in the 20th century in folk-dance clubs. A derivative found in the Francophone Lesser Antilles is known as kwadril, and the dance is also still found in Madagascar.
