Hildegard c. Hildegard was a noblewoman of Frankish and Alemannian heritage. Through eleven years of marriage with Charlemagne, Hildegard helped share in his rule as well as having nine children with him, including the kings Charles the Younger and Pepin of Italy and the emperor Louis the Pious.
Hildegard was the daughter of the Frankish count Gerold and his wife, the Alemannian noblewoman Imma. Thegan of Trier , a ninth-century biographer of Hildegard's son Louis emphasizes her Alemannian heritage and descent from duke Gotfrid through her mother, indicating that Imma was of higher status than Gerold. Charlemagne arranged to marry Hildegard and gain Gerold's support. Charlemagne took Hildegard to the Frankish royal palace at Thionville , where they stayed for two months before he set off on a campaign in Saxony.
Hildegard was heavily pregnant, and gave birth to a daughter named Adelhaid during the siege. They sent the baby back north to Francia for safety, but she died on the way. Martin made in both of their names. The royal family returned to Francia later in the summer of Hildegard had her final pregnancy in β, and she and Charlemagne stayed in the palace at Thionville during that winter.
Hildegard gave birth to another daughter in late April, but died shortly after on 30 April , possibly due to complications from the birth. The baby was named in her mother's honor, but also died less than two months later.
Hildegard was buried at the Abbey of Saint-Arnould at Metz, and Charlemagne arranged for her tomb to be perpetually lit and for daily masses to be said there, as well as commissioning an epitaph in her honor from his courtier Paul the Deacon.
