The American Square Dance became the official National Folk Dance of America by an act of Congress in 1982. Although the square dance contains some elements similar to the New England Quadrille, the Kentucky Running Set is thought to be the true foundation for its movements and configurations. The Running Set has been traced back to the source of all English country dances, the May-Day Round, and to early pagan ceremonials. The Square Dance evolved in the Appalachians, which were settled by people from Northern England and the lowlands of Scotland. A history is given of the evolution of the American Square Dance. The contents of the Congressional designation of the Square Dance as the National Folk Dance of America is presented, and it is noted that this resolution is ample justification for inclusion of contemporary square dance in the school curriculum.
