Teutberga

Teutberga (also spelled Theutberga; died 875) was a Frankish noblewoman and queen consort of Lothair II of Lotharingia. A member of the Bosonid dynasty, she became the central figure in one of the most politically charged marriage disputes of the 9th century. Her struggle to maintain her marriage and royal status against Lothair's efforts to annul the union became a defining case in medieval Church authority over marriage and annulment.
