The history of Irish dance started when the Celts arrived in Ireland from central Europe over 2,000 years ago. They brought with them their individual styles of dances and music. There are vague references to the early history of Irish dancing but evidence shows that its first participants were the Gaels. They danced in religious rituals honouring their pagan gods. Around 400 AD, after the conversion to Christianity, the new priests adopted the pagan style of art in creating their beautiful manuscripts, and the peasants kept the pagan style of music and dancing.
