Auvergne has been settled by humans since 10,000 B.C, but around 3000 B.C. the Celts and Arverni, whom the region was named after, settled Auvergne. The leader of the Arveni was Vercingetorix who defended Gallic independence against the Romans. As the most powerful Gallic tribe at the time they resisted Roman conquest from 52 B.C. to 53 B.C. When the Arverni lost to the Romans it marked the end of Gallic independence. After the collapse of the western Roman empire the region was divided among feuding vassals. In 1213, King Philippe-Auguste added Auvergne to the royal territory.
