Spain entered the twentieth century as a relatively underdeveloped nation still deeply rooted in her traditional past. Spanish life had barely begun to experience the stresses of social and economic transformation that recent scholars have identified with the modernization process. Toward the end of the last century, Spanish industry grew at a rapid pace, particularly in the Basque and Catalan regions, but the nation as a whole continued to lag behind the rest of Western Europe in the years before 1914. Although the recently formed trade union movements expanded in response to the new complex of urban-industrial problems, their organizational and political strength remained ineffective until World War I. In the other regions of Spain an agrarian economy, replete with strong anarchist movements, dominated and determined a social order in which provincialism, widespread subsistence living standards, and extensive illiteracy persisted.
