For more than 8 decades, many towns in the southwest of France have been preparing to host the biggest festivals in the Basque Country and Gascony: the ferias. This event is organized around the tradition of bullfighting, an ancestral activity that continues to exist and be transmitted. The ferias have diversified and offer folkloric animations and typical sports for all ages, within a convivial and festive atmosphere. In this context, this paper seeks to understand the origin of the Feria, along with its associated activities, in order to determine how it has become the symbol of the region reflecting its identity.
