The early history of Irish dance reveals a constant shifting of population through migration and invasions. Each of these peoples 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. 

The Anglo-Norman conquest in the twelfth century brought Norman customs and culture to Ireland. The Carol was a popular Norman dance in which the leader sang and was surrounded by a circle of dancers who replied with the same song. This Norman dance was performed in conquered Irish towns.

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.

When royalty arrived in Ireland, they were greeted at the shore by young women performing native dances. When King James landed at Kinsale, County Cork, in 1780, he was welcomed by dancers. Three people stood abreast, each holding ends of a white handkerchief. They advanced to slow music and were followed by dancing couples, each couple holding a handkerchief between them. The tempo of the music increased and the dancers performed a variety of lively figures.

Irish dancing was accompanied by music played on the bagpipes and the harp. In the houses of the Anglo-Irish aristocracy, the master often joined with servants in some of the dances. Dancing was also performed during wakes. The mourners followed each other in a ring around the coffin to bagpipe music.

During the eighteenth century, the dancing master appeared in Ireland. He was a wandering dancing teacher who travelled from village to village in a district, teaching dance to peasants. Group dances were developed by the masters to hold the interest of their less gifted pupils and to give them the chance to enjoy dancing. The standard of these dances was very high. Solo dancers were held in high esteem and often doors were taken off hinges and placed on the ground for the soloists to dance on.

Several versions of the same dance were to be found in different parts of Ireland. In this way a rich heritage of Irish dances was assembled and modified over the centuries. Today, jigs, reels, hornpipes, sets, half sets, polkas and step dances are all performed. Solo dancing or step dancing first appeared at the end of the eighteenth century.

The Irish word céili originally referred to a gathering of neighbours in a house to have an enjoyable time, dancing, playing music and storytelling. Today it refers to an informal evening of dancing. Céilis are held in large towns and country districts where young and old enjoy together group dances. The céili can be traced back to pre-famine times, when dancing at the cross-roads was a popular rural pastime.

Today there are many opportunities to watch and enjoy Irish dancing. It is still a regular part of social functions. Dancing sessions at céilis are usually preceded by a teaching period where novices are shown the initial steps. During the summer months, céilis are held in many Irish towns. Visitors are always welcome to join in and with on the spot, informal instruction, anyone can quickly master the first steps and soon share the Irish enthusiasm for Irish dance.
