Overview
Liutperga (Liutpirc) (fl 750 - fl. 793) was a Duchess of Bavaria by marriage to Tassilo III, the last Agilolfing Duke of Bavaria. She was the daughter of Desiderius, King of the Lombards, and Ansa.
Duchess of Bavaria
She was married to Tassilo at some point prior to 770, possibly in 763, to confirm the traditional alliance between Lombardy and Bavaria. The couple had four sons: Theodo, Cotani, Hrodrud and Theodebert.
Political agency
It has been argued that Liutperga resented the Frankish king Charlemagne. This argument is based on both the supposed repudiation of his marriage to Liutperga's sister Desiderata and his subsequent destruction of the Kingdom of Lombardy and imprisonment of her parents.
Liutperga played an apparently major role in her husband's opposition to Charlemagne. Frankish annals references to Liutperga suggest this. The Annales Mettense Priores refer to her as Tassilo's "wicked wife" and the Revised Royal Frankish Annals refer to the Liutperga's "urging" of her husband to push the Avars into conflict with Charlemagne.
