The term "Irish Tribes" refers to the various clans and groups that existed in ancient Ireland, particularly during the early medieval period. These tribes were often organized around a chieftain and shared common ancestry, language, and culture. Notable tribes included the Gaels, who were the dominant group, and the Tuatha Dé Danann, a mythical race associated with the gods of Irish mythology. Each tribe had its own territory and governance, often leading to conflicts and alliances with neighboring tribes. The social structure was hierarchical, with a clear distinction between nobles, warriors, and commoners. The influence of these tribes can still be seen today in Irish surnames and regional identities.
