Quadrille is the name of two loosely related card games of the Patience or solitaire type which are often confused. Both use a pack of 52 playing cards. The earlier one was also known as La Française ("the Frenchwoman") or Royal Quadrille, the slightly later one as Captive Queens. The name is derived from the desired outcome of the earlier game in which the four Kings and Queens are arranged in a square formation as in the European dance of quadrille that was fashionable in the 18th and 19th centuries.
