Bertrada of Laon

Bertrada of Laon (born between 710 and 727 – 12 July 783), also known as Bertrada the Younger or Bertha Broadfoot (cf. Latin: Regina pede aucae, i.e. the queen with the goose-foot), was the first Carolingian Frankish queen. An enduring influence in Frankish politics, she was the wife of Pepin the Short and the mother of Charlemagne, Carloman and Gisela, plus five other children. Her marriage with Pepin was influential in trend setting for future marriages blessed by the pope. She also held considerable influence over Charlemagne and Carloman after Pepin had died, enduring even past her death and through Charlemagne’s eventual rule as the sole King of the Franks.
