Origins and Features of Early Cities

Origins of Urbanisation

The shift from nomadic bands to settled villages occurred during the Neolithic, when durable stone tools enabled agriculture, animal husbandry, food storage, and permanent building. Improved nutrition and longevity followed as environment, technology, and social structure aligned for the first time.

Childe’s “Urban Revolution”

According to Childe, the transformation from villages to cities (from roughly $10\,000\ \text{BCE}$ villages to around $3500\ \text{BCE}$ cities) was long and gradual. Cities were marked by high‐density populations, specialized craft classes, advanced government, fortifications, and permanent urban habitats supported by surrounding farmland and infrastructure.

Transformation of Social Organisation

Early kin-based groups (bands, tribes) gained additional layers of organisation—religious hierarchies, guilds, classes, ethnic and political bodies—allowing decisions and actions beyond family ties. This social stratification culminated in city-states, replacing egalitarian patterns with ranked power structures.

Core Functions of Early Cities

First cities served as hubs for trade in farm goods and crafts, religious activity centered on large temples, political–military control, and administration. Despite urban concentration, economic dependence on rural hinterlands for food and raw materials remained strong.

River Valleys as Cradles of Cities

River valleys provided natural boundaries, drew populations during regional drying, and experienced annual inundations that deposited nutrient-rich alluvial silt. Indigenous grasses were easily domesticated; pottery enabled surplus storage; and settlements often formed on elevated “tels.”

Religion, Power, and Social Cohesion

The ‘god-king’ model fused religious and secular authority, legitimising rulers who organised labour for irrigation, warfare, and public works. Religion evolved from dispersed hunter-gatherer practices to hierarchical temple worship handled by a professional priesthood.

Language and Empire

Shared language, often tied to religion, facilitated administration and social mobility. Mastery of the elite tongue became a gateway to power and knowledge, reinforcing cohesion in expanding realms.

Key River-Valley Civilisations

Sumer in Mesopotamia (c. $5000–2000\ \text{BCE}$) was a network of city-states like Ur and Babylon. The Indus civilisation (c. $3300–1700\ \text{BCE}$) built Harappa and Mohenjo-Daro, introduced plough use and standardised weights. Egypt’s Nile culture (c. $5000–322\ \text{BCE}$) produced planned cities such as el-Amarna. All leveraged riverine fertility, surplus agriculture, and theocratic rule.

Diffusion of Urbanisation

From Mesopotamia, Nile, Indus, and Yellow River hearts, urban forms radiated across the Mediterranean, Europe, East Asia, and the Americas over millennia, culminating in global urban networks by the modern era.
