During Spain’s Second Republic, Catholic political activists formed Acción Obrerista, a confessional political party for members of the working class. Its leaders aligned themselves with the largest Catholic political organization of the Republic. Many workers viewed Acción Obrerista as a tool used by employers to weaken the working class, and many middle-class Catholics wanted more control over the working-class movement. Acción Obrerista’s failure to allay these suspicions stunted its growth, and the Catholic movement replaced it with a nonpolitical labor movement. Its failure helped discredit confessional labor organization in Spain.
