A war between brothers gives Auvergne to France

At the beginning of the 13th century, the Count of Auvergne attacks his bishop brother and religious buildings, pushing King Philippe-Auguste to intervene. The sovereign dispatches an army led by Guy de Dampierre to subdue more than one hundred and twenty strongholds in three years. The capture of the castle of Tournoël in December 1213 seals the definitive annexation of the region to the royal domain of France.
