Historical Context

Industry in Spain is primarily concentrated in the periphery rather than the center of the peninsula. Throughout the industrialization process that began in the 17th century, a constant dichotomy persisted between the center and the periphery. Only Madrid successfully achieved an industrialization process comparable to the periphery. This duality remains today, influenced by mountainous terrain that complicates transport and the economic interests of foreign companies that control much of the industrial fabric.
