The early history of Irish dance reveals a constant shifting of population through migration and invasions. Many of these people brought their preferred types of dance and music. There are only vague references to the early history of Irish dancing, but there is evidence that among its first practitioners were the Druids, who danced in religious rituals honouring the oak tree and the sun. Traces of their circular dances survive in the ring dances of today. When the Celts arrived in Ireland from central Europe over two thousand years ago, they brought with them their own folk dances.
Three principal Irish dances are mentioned often in sixteenth century writing: the Irish Hey, the Rinnce Fada (long dance) and the Trenchmore. One of the first references to dance is in a letter written by Sir Henry Sydney to Queen Elizabeth I in 1569. "They are very beautiful, magnificently dressed and first class dancers," Sydney wrote of the girls he saw dancing enthusiastic Irish jigs in Galway.
Sydney went on to describe the dance formation, observing the dancers in two straight lines which suggests they were performing an early version of the long dance.
During the mid sixteenth century, dances were performed in the great halls of the newly built castles. Some of the dances were adapted by the sixteenth century English invaders and brought to the court of Queen Elizabeth. One of these dances was the Trenchmore, which was an adaptation of an old Irish peasant dance. From this period onward another style of dance called the Hey was popular where female dancers wound in around their partners, in a fore-runner of the present day reel.
Irish dancing was accompanied by music played on the bagpipes and the harp.
