 The governor of Vienne, Boson of Provence, proclaimed himself king of Burgundy and the region became part of the Kingdom of Arelat, which remained independent until 1032, when it became part of the Holy Roman Empire.At that time, the development of feudal society and the weakness of the Emperor's rule allowed for the creation of several small ecclesiastic or secularist States (the region of Viennois, for example, was under the rule of the archbishop of Vienne).In the middle of that chaos, the Counts of Albon succeeded in uniting these different territories under their rule.
