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 and is within old Jamaican / Caribbean culture.
The quadrille consists of a chain of four to six contredanses, courtly versions of English country dances that had been taken up at the court of Louis XIV and spread across Europe. Latterly the quadrille was frequently danced to a medley of opera melodies.
The term quadrille originated in 17th-century military parades in which four mounted horsemen executed square formations. The word probably derived from the Italian quadriglia (diminutive of quadra, hence a small square).
The dance was introduced in France around 1760: originally it was a form of cotillion in which only two couples were used, but two more couples were eventually added to form the sides of a square. The couples in each corner of the square took turns, in performing the dance, where one couple danced, and the other couples rested. The "quadrille des contredanses" was now a lively dance with four couples, arranged in the shape of a square, each couple facing the center. One pair was called the "head" couple, the adjacent pairs the "side" couples. A dance figure was often performed first by the head couple and then repeated by the side couples. Terms used in the dance are mostly the same as those in ballet, such as jeté, chassé, croisé, plié and arabesque.
