Reginar, Duke of Lorraine

Reginar Longneck was the leading noble of Lotharingia at the end of the 9th century. He held counties around the Meuse and Scheldt, including Hainaut, and lay abbacies such as Echternach, and was recognised as duke or margrave in Lotharingia. His descendants, the Reginarids, became counts of Hainaut and later dukes of Brabant.
