Abbot William. Marriage and children Berthold married one Richwara, possibly a descendant of Duke Conrad II of Carinthia. The couple had at least three sons: Herman I ( – 1074), used the Veronese margravial title and became progenitor of the Margraves of Baden Berthold II ( – 1111), Duke of Swabia in opposition to Frederick of Hohenstaufen from 1092 to 1098, then Duke of Zähringen Gebhard ( – 1110), Bishop of Constance from 1084. Richwara also gave birth to two daughters: Liutgard (d. about 1119), married the Nordgau margrave Diepold of Vohburg; mother of Margrave Diepold III and grandmother of Adelaide of Vohburg, the first wife of Emperor Frederick Barbarossa Richinza, married Count Rudolf of Frickingen, secondly married to Louis of Sigmaringen, progenitor of the House of Helfenstein. In his second marriage, Berthold was married to Beatrice, sister of Count Theodoric I of Montbéliard. In the end, the Zähringer were able to maintain their position, when around 1098 Berthold II reached an agreement with the Hohenstaufen duke Frederick I of Swabia, retaining the title of "Duke of Zähringen". From 1112, Herman II, son of Herman I, ruled as Margrave of Baden. Notes References House of Zähringen Dukes of Carinthia 1000s births 1078 deaths Year of birth uncertain
