wife until her death. She has mostly been looked upon as only a wife and mother and nothing more, much like the women who lived at this time no matter the class. But she was more than that. Her life was more defined by what she did rather than what she was. When Charlemagne married her, he was coming out of his second divorce. She was his first wife that he stayed with till she died. This started a trend of Charlemagne staying with whoever he was married to for his last three wives. Children Although Charlemagne already had an older son (Pepin the Hunchback) from his first union with Himiltrude, he was not considered an heir after the rebellion in which he participated in 792.
