Adelaide was born circa 1065 to Rudolf of Rheinfelden, duke of Swabia and German anti-king, and his second wife, Adelaide of Savoy.[1] Her maternal aunt was Bertha of Savoy, who was married to Henry IV of Germany.

Around 1077/8 Adelaide married Ladislaus I of Hungary, a member of the Árpád dynasty.[2] Ladislaus agreed to support Rudolf in his struggle for the throne against Henry IV of Germany. In 1079 Adelaide’s mother died, followed in 1080 by her father, who fell at the Battle of Elster.[1]

In 1081 Pope Gregory VII wrote to Adelaide, urging her to encourage her husband to support monasteries and be generous to the poor and the weak.[3]

Adelaide died in May 1090; her husband outlived her by 5 years. She was buried in Veszprém, where her gravestone remains.


Adelaide had two children:

  • Piroska of Hungary (c. 1080 – August 13, 1134), wife of John II, emperor of the Byzantine Empire[1]
  • Unknown daughter (? – ?), wife of Prince Yaroslav of Volhynia.
