Why did Brittany remain socially and religiously conservative during the 19th and 20th centuries?

During the 19th and 20th centuries, Brittany maintained a socially and religiously conservative character due to the deep-rooted influence of the Roman Catholic Church and the preservation of traditional social structures.1

The region’s conservatism was reinforced by several key factors:

• Religious Devotion: The Catholic faith remained central to Breton life, evidenced by the continued importance of traditional pilgrimages, known as pardons, held in locations such as Locronan, Josselin, and Ste. Anne d’Auray.1
• Social Hierarchy: Unlike many other parts of France, Brittany preserved much of its old social organization. In rural areas, families remained large and were characterized by a strong devotion to paternal authority, while the rural nobility continued to exercise significant social influence.1
• Cultural Identity: A strong Celtic background and the persistence of the Breton language helped distinguish the region from the rest of France, fostering a sense of uniqueness that often aligned with traditionalist values.1

This combination of religious practice, patriarchal family structures, and a distinct regional identity allowed Brittany to resist broader national trends toward secularization and social change throughout this period.1
