The quadrille, named for its four couples that form the sides of a square, seems to have begun as a French country dance. In the 18th century it became fashionable among the French nobility; as performed by elegantly dressed aristocrats, it became slow and formal. It crossed over to England and from there to New England, where it turned back into a dance for the common people. It soon evolved into the American square dance, a lively type of dance that employs a "caller" to make sure everyone remembers the steps.
