Teutberga

Teutberga (died 11 November 875) was a daughter of Bosonid Boso the Elder and sister of Hucbert, the lay-abbot of St. Maurice's Abbey.

For political reasons, to forge ties of kinship with the Carolingian dynasty, the imperial family of Francia, in 855 she was married to the Carolingian Lothair II, the second son of Emperor Lothair I. It is very probably that Lothar II, at the time of marriage, already had a mistress named Waldrada, who, according to historian Baron Ernouf, was of noble Gallo-Roman family, whose brother, Thietgaud, was the bishop of Trier and her uncle, Ghunter, was archbishop of Cologne, while, according to the Annales Novienses, she was the sister of Ghunter. According to the Vita Sancti Deicoli, Waldrada was related to Eberhard II, Count of Nordgau (included Strasbourg) family of Etichonids.

Soon after their marriage, Lothair's father died and Lothair II inherited Middle Francian territory west of the Rhine stretching from the North Sea to the Jura mountains. Teutberga was not capable of bearing children and Lothair's reign was chiefly occupied by his efforts to obtain an annulment of their marriage, prompted also by his affection for Waldrada. His relations with his uncles Charles the Bald and Louis the German were influenced by his desire to obtain their support for this endeavor. Although quarrels and reconciliations between the three kings followed each other in quick succession, generally Louis favoured annulment, and Charles opposed it, while neither lost sight of the fact that Lothair had no legitimate sons to inherit his lands.
