Urban Revolutions: When the City Invents Another World

May 2, 2026. The city is not simply an extension of the village. It builds upon certain dynamics, but profoundly transforms their nature. In many respects, it represents a rupture. One of the great turning points in human history occurred during the Neolithic period, when humans, after millennia of adapting to their environment, made a decisive choice: to settle. This shift paved the way for major transformations - agriculture, specialization, division of labor - that permanently altered the relationship between humans and space. But this was not yet the city. A second turning point was needed.

A First Urban Revolution: Organizing Complexity

With the emergence of the first urban societies in Mesopotamia, and particularly Uruk in the 4th millennium BCE, a new form of organization appeared. In the 20th century, the archaeologist V. Gordon Childe described this transformation as the “urban revolution.”

Uruk was not merely a large human settlement. It marked a shift in both scale and nature. It exhibited population concentration, social stratification, specialized functions, monumental architecture, extensive trade networks, and above all, a decisive innovation: writing. The city thus became an organized, administered, and conceptualized space - where power, economy, religion, and knowledge intersected.

But this transformation was not simply a matter of growth. It introduced a new way of conceiving space.

At Habuba Kebira in present-day Syria, one of the earliest examples of planned urbanism emerged: structured streets, regular plots, and spatial hierarchies. Here, the city was conceived as a project.

It was no longer merely inhabited.It was organized as a system.

Other urban centers emerged in parallel - in the Indus Valley, Egypt, China, and Mesoamerica -suggesting that this shift was not isolated, but reflected a deeper transformation of human societies.

For V. Gordon Childe, several criteria distinguish cities from villages: density, functional specialization, surplus production, political organization, writing, and monumental architecture. Yet beyond these characteristics, what emerges is a fundamental shift in nature. The city introduces a new level of complexity. It transforms social relations, modes of production, and forms of power.

As Jean-Claude Margueron has shown, even a very large village does not necessarily become a city. The needs, functions, and spatial logics differ profoundly. The city thus appears as a specific form of organization: a structured, constrained space embedded in exchange networks and regulated by institutions. With the city, humanity no longer simply inhabits a territory.It structures it, administers it, and projects it.

Another Urban Revolution: The City as Social Production

Childe’s analysis allows us to understand the city as a historical rupture.But this rupture is not confined to the past. Several decades later, the philosopher Henri Lefebvre offered a radical reinterpretation. For him, the “urban revolution” does not only refer to the emergence of the first cities—it describes an ongoing historical process. The city is not merely a spatial form inherited from the past. It is a social production. It is shaped by social relations, economic forces, political choices and the practices of those who inhabit it.

Organizing space is always about organizing power relations. In this perspective, the city appears both as one of the most advanced forms of human organization - and as one of its primary fields of tension.

Where Childe highlights the conditions of the city’s emergence, Lefebvre emphasizes its dynamics: the city as a contested space, shaped by struggles over its appropriation and transformation.

The “right to the city”, which he formulated in the late 1960s, does not simply refer to access to urban space. It refers to the capacity of societies to participate in its production.

Who produces the city?

For whom is it produced?

And according to which logics?

The City as a Political Fact

Taken together, these approaches reveal a fundamental continuity. Since its origins, the city has never been neutral.It is both a living environment and an instrument for organizing power. It concentrates resources, flows and decision-making capacities.

Building a city always involves choices.

Which territories to develop ?

Which populations to prioritize ?

Which interests to serve ?

From Mesopotamian city-states to contemporary metropolises, including imperial, industrial, and colonial cities, each urban model reflects a particular way of organizing social relations and power structures. The city is a political landscape.

An Ongoing Urban Revolution

From this perspective, the urban revolution cannot be reduced to a past event.It continues today through contemporary transformations. As the planet becomes increasingly urbanized, the question is no longer only how cities are produced, but how they are appropriated.

Who has the right to inhabit?

Who has the power to transform the city?

Under what conditions?

These questions extend those raised at the origins of the city, but within a profoundly transformed context.

Conclusion : An Open Question

Speaking of an “urban revolution” is not merely a way of describing the past.It is to recognize that the city is an ongoing historical process. A process shaped by collective choices, power relations, and conditions of existence. And one that leads today to a central question : What kind of city are we producing, and for whom?

But perhaps we need to go further. The transformations currently underway - resource pressures, climate crises, and growing inequalities - suggest that we are not simply entering a new phase of urbanization. We may be on the threshold of a new urban revolution. A revolution that is no longer only about the production of the city,but about what makes it possible. No longer just organizing, producing, or expanding the urban, but ensuring the conditions of existence within the city.

This shift is not a step backward. It marks a deeper transformation: a world in which the very possibility of existing in urban space becomes uncertain. And where the question is no longer only how we produce the city,but whether it can still be inhabited, and by whom.
