English country dance was the progenitor of several other dance forms. The French contredanse, arriving independently in the American colonies, became the New England contra dance, which also experienced a resurgence in the mid-20th century. The French expression of English country dance may also have contributed to the development of the quadrille, though this is debated. The square-eight form of English country dance had fallen from favour by the time the French received it, and the earliest French works contain only the longways form.[9] The quadrille evolved into square dance in the United States, while in Ireland, it contributed to the development of modern Irish dance. English country dance in Scotland developed its own flavour and became the separate Scottish country dance. English Ceilidh is a special case, being a convergence of English, Irish and Scottish forms. In addition, certain English country dances survived independently in the popular repertoire. One such is the Virginia Reel, which is almost exactly the same as the English country dance 'Sir Roger de Coverly'. English country dance can therefore be seen as the ancestor of a whole family of social folk dances in the Anglosphere.
