Folk dances are dances developed by groups of people that reflect the traditional life of the people of a certain country or region. Not all ethnic dances are folk dances; for example, ritual dances or dances of ritual origin are not considered to be folk dances.
Ritual dances are usually called "Religious dances" because of their purpose. The terms"ethnic" and "traditional" are used when it is required to emphasize the cultural roots of the dance. In this sense, nearly all folk dances are ethnic ones.
