The Déisi were a socially powerful class of peoples from Ireland that settled in Wales and West England between the ancient and early medieval period. The various peoples listed under the heading déis shared the same status in Gaelic Ireland, and had little or no actual kinship, though they were often thought of as genetically related. During the Early Middle Ages some Déisi groups and subgroups exerted great political influence in various parts of Ireland, and certain written sources suggest a connection to Britain as well. During early medieval Munster, the Déisi were under the hegemony of the Eoganachta confederacy.
