Urbanization refers to the process through which cities and towns grow as a result of the migration of people from rural areas and the expansion of urban areas. It is a phenomenon that has shaped human history for thousands of years, influencing every aspect of society from economics to culture and beyond. As populations increase, the desire for better living conditions, access to employment, and social interaction has led individuals to seek opportunities in urban centers. Over time, these cities evolve to accommodate larger populations, evolving into complex hubs of commerce, culture, and technology.

The roots of urbanization trace back to the early agricultural revolution, which enabled humans to produce food more efficiently and settle in one place. This change allowed small villages to grow into the first cities, creating more permanent centers of human life. As civilizations advanced, cities became focal points for trade, governance, religion, and culture. Each of these elements played a crucial role in promoting further urban development, as settlements began to specialize in various industries, services, and functions that drew people from surrounding rural regions.

Historically, urbanization was most prominent in ancient civilizations such as Mesopotamia, Egypt, and later, Greece and Rome. These early cities, though primitive by modern standards, laid the foundations for the urban environments we know today. Greek and Roman cities were carefully planned, with infrastructures like roads, aqueducts, and public spaces that contributed to their growth and sustainability. In more recent centuries, urbanization expanded rapidly during the Industrial Revolution, driven by advances in technology, industry, and transportation. Factories, railroads, and new employment opportunities in cities attracted millions of people, transforming landscapes and social structures in profound ways.
