Evolution of Urbanization: From Pre-Industrial to Modern Eras

The Urbanization Process

Pre-Industrial Urbanization

Pre-industrial urbanization was driven by strategic, military, political, economic, administrative, and religious factors. The stages of urbanization regarding its origins are as follows:

• Ancient Roots: Before Phoenician and Greek colonization, cities were scarce in Spain. Romanization later led to the foundation of numerous urban centers.
• Medieval Decline and Resurgence: Following the fall of the Roman Empire, Germanic invasions triggered a phase of de-urbanization. During the Middle Ages, development occurred in two distinct spaces: Muslim and Christian.
• Muslim and Christian Territories: The Muslim space comprised almost the entire southern half of the peninsula, while urban life was scarce in the Christian north.
• Reconquista: Urban life expanded in the 11th century with the Reconquista and subsequent repopulation efforts.

Urbanization in the Modern Era experienced demographic, economic, and political fluctuations:

• 16th Century: Urban growth increased due to economic expansion and the military might of the Habsburgs.
• 17th Century: A period of demographic and economic crisis.
• 18th Century: Urbanization was revitalized under the new Bourbon dynasty.

Industrial Urbanization

Industrial urbanization spanned from the mid-19th century until 1975. During this stage, the urbanization rate experienced significant growth, as the increase in the urban population surpassed that of rural areas. Administrative, economic, and social factors drove this process, which is divided into four cycles:

• Mid-19th Century: Demographic concentration in cities remained small.
• Late 19th Century to Civil War: Significant growth occurred in major cities.
• Post-Civil War: Growth slowed due to destruction and supply problems caused by the conflict.
• Mid-20th Century: This was the stage of greatest economic and urban growth, primarily caused by industrial expansion, which drew labor from rural fields to large industrialized cities.

Post-Industrial Urbanization

The pace of urban growth declined in two stages: a transition period where the urbanization rate stabilized, and a period of de-urbanization where city growth decreased. Factors of urbanization shifted:

• De-industrialization: Industry lost importance as an urbanizing factor after 1975, leading to a decline in cities heavily affected by the shift in industrial production.
• New Technology Sectors: High-tech industries are attracted to large, well-equipped metropolises that offer necessary services and infrastructure.
• Tertiary Sector: Service and sports activities have gained relevance as urbanization factors.
• Decentralization: In the post-industrial stage, the process has slowed in major cities, favoring the growth of medium and small towns.
