Irish dances can be divided into social dances like ceili and sets, and performance dances like solo step dances. Social dances involve dancing in pairs or groups of 2-8 people, while solo step dances feature quick and precise foot movements. During British colonization of Ireland, laws were introduced banning the teaching of Irish culture including music and dances. Over 150 years, Irish dances were taught secretly. The modern dance school system was established in the early 1700s. Popular Irish dances include jigs, reels, and hornpipes, each with distinct music and footwork. Famous Irish dancers like Michael Flatley have performed internationally and set speed records in step dancing.
