Humbert II of Viennois

Humbert II de la Tour-du-Pin was the Dauphin de Viennois, from 1333 to 1349. His feudal domains, known as the Dauphiné, belonged to the Kingdom of Burgundy (Arles), under the suzerainty of the Holy Roman Empire. Humbert was the last dauphin from the local line of Counts of Albon and Dauphins of Viennois, and being childless, he decided to sell his domains to the House of Valois in 1349, relinquishing his lands and titles on 16 July to the young French prince Charles, and dedicating the rest of his life to an ecclesiastical career.
