Enrique III el Negro
Agnes and Geoffrey stayed in Germany at the imperial court, so her daughter Agnes could marry Henry III, Holy Roman Emperor. They then bonded with the imperial couple, during a trip to Italy where they participated in the council of Sutri, filing and inducting two popes Pope Clement II, who was quick to crown the emperor and empress. After a pilgrimage to Monte Garaño, the couple went back to Poitou in 1047 where they founded Sainte-Marie-des-Dames. Between 1047 and 1049, Agnes founded the abbey of Saint Nicolas de Poitou.
