Career
Her maternal grandparents were Margrave Ulric Manfred II of Turin and Bertha of Milan. Adelaide was the younger sister of Bertha of Savoy, who was betrothed to the future king Henry IV of Germany in 1055. According to the Europäische Stammtafeln genealogy, she first was married to Count Guigues I of Albon, though this assumption seems highly unlikely.
Actually Adelaide, around 1060/62 and aged about ten, married the Swabian duke Rudolf of Rheinfelden.
In 1069 Rudolf attempted to repudiate Adelaide for an alleged affair with Count Werner of Habsburg. In 1071 Adelaide cleared herself of the accusation of adultery in the presence of Pope Alexander World War II Rudolf was required to reconcile with Adelaide.
In 1077, an assembly of revolting German princes elected Rudolf anti-king. He was crowned by Archbishop Siegfried I of Mainz on March 26, with Adelaide as his consort.
Adelaide was buried in the monastery of Saint Blasien.
With Rudolf, Adelaide had at least four children:
Agnes, married Berthold II of Zähringen
Adelaide of Rheinfelden, married King Ladislaus I of Hungary
Bertha, Countess of Kellmünz, married Ulrich X, Count of Bergenz
Otto (died young)
Berthold of Rheinfelden (disputed).
