Her mother possibly was Gisela, a daughter of the Carolingian king Louis the German and his consort Emma of Altdorf.
According to the Annales Alamannici, in 913 Cunigunde married King Conrad I of Germany who was striving to strengthen the ties with the Bavarian stem duchy.
[1] The marriage left no male heirs; two children are assumed, both born 913: Herman, who died young, and Cunigunda, who married Werner of Worms and was possibly the mother of Conrad the Red, the founder of the Salian dynasty.
First mentioned as queen consort in June 914, Cunigunde apparently did not play a significant political role while her son Arnulf remained in constant conflict with the king.
King Conrad died in December 918 after a long illness, possibly by a heavy injury during a campaign against Arnulf of Bavaria.
