Saint Richardis, also known as Richgard, Richardis of Swabia and Richarde de Souabe in French, was empress of the Carolingian Empire as the wife of Charles the Fat. She was renowned for her piety and was the first abbess of Andlau. Repudiated by her husband, Richardis later became a Christian model of devotion and just rule. She was canonised in 1049.
