Richardis
Saint Richardis, also known as Richgard, Richardis of Swabia and Richarde de Souabe in French (c. 840 – 18 September, between 894 and 896), was the Holy Roman Empress 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.
Life
She was born in Alsace, the daughter of Erchanger, count of the Nordgau, of the family of the Ahalolfinger. She married Charles in 862 and was crowned with him in Rome by Pope John VIII in 881. The marriage was childless.
Charles' reign was marked by internal and external strife, caused primarily by the constant plundering of Norman raiders on the northern French coast. These attacks had intensified as the aggressors, no longer content to pillage the coastline, had moved their attentions to cities and towns along the rivers. The Carolingian world was unable to effectively deal with these external threats.
