Early History

The province took its name from the Arverni, a Gallic tribe who was defeated by Roman general Julius Caesar.  The Gallic capital was destroyed by the Romans, and was replaced by the colony of Augusto-Nemetum, which later became Clermont.  Auvergne was included in the newly conquered land that Caesar called Aquitaine. In 507, Auvergne was conquered by the Frankish king Clovis I.

Early Middle Ages

In about 928, Auvergne became the possession of the Count of Toulouse. In the 12th century, Auvergne became a possession of the English king, Henry II, upon his marriage to Eleanor of Aquitaine.  From the end of the 13th century the area of Auvergne became known as the Dauphine d’Auvergne.

Late Middle Ages

In 1360, John II of France made the area known as the Terre d’Auvergn into a duchy for his son Jean. With the end of the Hundred Years’ War in 1453, the English had been driven from France.  In 1503, Charles united the Dauphiné and the duchy.  After Charles’ treason, the domains were taken by King Francis I and given to his mother, Louise of Savoy.  The domain was annexed to the kingdom of France in 1532.  

Post Renaissance to Modern Day

In 1790, the modern departements of Puy-de-Dome, Cantal, and part of Haute-Loire were formed from the old province of Auvergne.  In the same year, the departement of Allier was formed from what used to be the province of Bourbonnais and part of the old province of Auvergne.
