Why did Barcelona become a center of anti-Catholic and anarchist activity in Spain?

Barcelona became a prominent center of anti-Catholic and anarchist activity due to a combination of rapid industrialization, intense class conflict, and a long-standing tradition of regional resistance to central authority.

Industrialization and Social Conflict

During the 19th century, Barcelona was reshaped by the Industrial Revolution, which transformed it into Spain’s most modern city and the wealthiest region in the country. This economic shift led to rapid population growth and the emergence of deep-seated class conflict between the bourgeoisie and the industrial working class. Anarchist movements flourished in this environment, as workers sought leaders who would challenge both the military and employers, the latter of whom often hired gunmen to engage in street-level conflict with labor organizations.123

Anticlericalism and Anarchism

Barcelona had a long-standing tradition of anti-Catholic sentiment. The city’s anarchist movement, which became the most powerful in the world, was characterized by its rejection of political action in favor of direct action and syndicalism. This radicalism frequently manifested in violent outbursts against the church, which was often viewed as a symbol of the establishment and a defender of the status quo. Notable instances include:43

• 1835 Uprising: Convents were burned during civil unrest.2
• Tragic Week (1909): Triggered by the conscription of reservists for the war in Morocco, this event saw mobs burn approximately 50 churches and monasteries.32
• Labor Unrest: The National Confederation of Labor (CNT), founded in 1910, became a model of anarchist decentralism, providing a structure for workers to challenge the bourgeois state.53

Ultimately, the city's role as a hub for these movements was fueled by the perception that the church and the state were inextricably linked in suppressing the rights and aspirations of the Catalan working class.14
