Bertha (died after 1014) was the wife of Arduin of Ivrea. She was thus margravine of Ivrea and queen of Italy (1002-1014).
Her parentage is unknown, but she is often said to be identical with Bertha of Milan, who was a member of the Obertenghi dynasty. Other scholars suggest that Bertha may have been the daughter of Hubert of Tuscany[1] or of Amadeus (son of Anscar II)[2]
Bertha intervened in eight of Arduin's royal diplomas,[3] in which she was often called his consors regni (royal consort).[4]
With Arduin, Bertha had three sons:[5]
- Arduin (sometimes called Ardicino)
- Otto
- Guibert.
