Irish dance: Irish dance or Irish dancing is a group of traditional dance forms originating in Ireland, encompassing dancing both solo and in groups, and dancing for social, competitive and performance purposes.  Irish dance in its current form developed from various influences such as French quadrilles and English country dancing throughout the 18th and 19th centuries.  Dance was taught by "travelling dance masters" across Ireland throughout this period, and separate dance forms developed according to regional practice and differing purposes.

From the early 20th century, a number of organisations promoted and codified the various forms of dance, creating competitive structures and standardised styles.
