Over the next 20 years, her own status was elevated when Charles (almost through no actions of his own) became King of West Francia, King of Italy, King of East Francia, and finally Emperor of the Carolingian Empire in 881, when Richardis was crowned empress along with her husband. Charles was not very effective—he was just in the right place at the right time. He was traveling frequently to Italy and fumbling dealing with internal and external strife.
We know little about Richardis' life during this time. We do know that they had no children, which is a problem for rulers who want to leave their kingdoms to their offspring. The common solution to this for a ruler is to divorce the wife and marry again. Charles seemed to decide the best way to do this in 887 was to accuse Richardis of adultery with Charles' archchancellor, Bishop Liutward of Vercelli.
Richardis was subjected to Trial by Ordeal, which despite the 15th century depiction above, was usually having the defendant hold a piece of red-hot iron, then examining their hands for damage. She passed the ordeal. The pope put together a commission to handle Charles' request for annulment. An examination of Richardis by the commission concluded that she was still a virgin.
In 880, she had founded Andlau Abbey on her ancestral lands in northeast France, 20 kilometers north of where Charles had built his new palace in Selestat. She retired there now under the abbess Rotrud, her niece. She died on 18 September 880.
Then the legends began, of a virtuous wife harried by a mad husband. She finally agrees to go through ordeal by fire, being tied to a stake above a fire. Despite wearing a simple shirt covered in wax and being barefoot (see illustration), she survives with no marks on her. Afterward, she leaves her husband and wanders in the woods. An angel appears to her and tells her to found a convent where a bear indicates. This becomes Andlau Abbey. (Of course, Andlau was founded years earlier than the ordeal.)
The bear became part of her iconography. The nuns at Andlau kept a live bear on the grounds, and gave free lodging to bear-keepers. She is sometimes pictured with a bear. She was canonized by Pope Leo IX in 1049, the patron saint of protection against fire.
And speaking of Pope Leo IX...his reign was very consequential, and he is responsible for the final break between the Western Roman and Eastern Orthodox Churches. Let's talk about him next.
