query: Who were the Reginarids?
answer: The Reginarids were a family of powerful figures (magnates) in Lower Lotharingia during the Carolingian and Ottonian periods.  Their name comes from a common family name, and they included at least two Dukes of Lotharingia in the 10th century.  They had a long history of conflict and alliances, influencing the establishment of several counties and duchies, and their descendants are connected to prominent European families.
