Irish stepdance is a type of performance dance originating in Ireland from traditional Irish dance. Irish stepdancing has been recently popularized by the world-famous show "Riverdance" and its followers. Irish stepdance is performed in most places with large Irish populations, though not all stepdancers are of Irish ancestry. Aside from public dance performances, there are also stepdance competitions in Ireland, the United Kingdom, and North America. Most competitive stepdances are solo dances, though many stepdancers also perform and compete using traditional set and céilí dances. When performed as a solo dance, it is generally characterized by a stiff upper body and the quick and precise movements of the feet.
