Eóganacht Glendamnach was a branch of the Eóganacht dynasty in ancient Ireland, specifically associated with the region of Munster. This lineage played a significant role in the political landscape of early medieval Ireland, particularly during the 7th and 8th centuries. They were known for their influence and power, often competing with other dynasties for control over territories. The name "Glendamnach" refers to a specific area, likely linked to the River Glan in County Kerry. Members of this dynasty were often involved in local governance and military affairs, contributing to the cultural and political development of their time. Their legacy is part of the broader history of Irish kingship and tribal organization.
