Ermengard of Italy

Ermengard of Italy was the queen of Provence as the spouse of King Boso. She was the second and only surviving child of Emperor Louis II. In her early life, she was betrothed to Constantine, the junior Byzantine emperor, but whether the marriage actually occurred or not is still debated among historians. In 871, Ermengard and her family were taken hostage by Adelchis of Benevento but were later freed. In 876, Ermengard married Boso, a nobleman with connections to the Carolingian dynasty, and became queen upon his accession to the throne of Provence in 879. After her husband's death in 887, she ruled the kingdom as regent during the minority of their son Louis the Blind.
