The greatest of the free counts was Renaud III, who, from 1127, used the title "franc-comte" as a sign of independence of German or Imperial authority, but was forced to submit to Conrad III. His daughter and heiress, Beatrice, married Frederick Barbarossa and united the Anscarid inheritance with that of the Hohenstaufen. Burgundy was inherited by her son Otto I, who had an Anscarid name. Thus the county was lost for the House of Ivrea, but it came back when Hugh of Chalon married to Adelaide countess of Burgundy, daughter of Beatrice II of Hohenstaufen (Otto I's daughter). However, in 1315 died Robert, Count of Burgundy, last male of the main line and the county inherited to the Dampierre family and finally to the Capetian-Valois dukes of Burgundy.
