Connacht or Connaught is one of the Provinces of Ireland situated in the west of Ireland. In Ancient Ireland, it was one of the fifths ruled by a "king of over-kings" (in Irish: rí ruirech). In Gaelic historical annals from old Irish it was described as a western kingdom of learning, the seat of the greatest and wisest druids and magicians and where the men are famed for their eloquence, their handsomeness and their ability to pronounce true judgement.

It is said that the Fir Bolg ruled all of Ireland right before the Tuatha Dé Danann arrived. When the Fir Bolg were defeated, the Tuatha Dé Danann were so touched by the courage of their enemy that they would give them a quarter of Ireland. They chose Connacht.
