This is a biography of Earthopolis, the only Urban Planet we know of. It is a history of how cities gave humans immense power over Earth, for good and for ill. Carl Nightingale takes readers on a sweeping six-continent, six-millennia tour of the world's cities, culminating in the last 250 years, when we vastly accelerated our planetary realms of action, habitat, and impact, courting dangerous new consequences and opening prospects for new hope. In Earthopolis we peek into our cities' homes, neighborhoods, streets, shops, eating houses, squares, marketplaces, religious sites, schools, universities, offices, monuments, docklands, and airports to discover connections between small spaces and the largest things we have built. The book exposes the Urban Planet's deep inequalities of power, wealth, access to knowledge, class, race, gender, sexuality, religion and nation. It asks us to draw on the most just and democratic moments of Earthopolis's past to rescue its future.

This Element offers seven propositions toward a theory of 'Our Urban Planet' that is useful to global urban historians. I argue that historians have much to offer to theorists particularly those involved in debates over planetary urbanization theory and the Anthropocene. We must enlarge our concept of 'urban' to include spaces that make cities possible and that cities make possible and become comfortable with longer temporal frames that nest global urban history within Earth Time. Above all we need to add the crucial dimension of power, redefining cities as spaces that humans produce to amplify harvests of geo-solar energy and deploy human power within space and time. The element uses insights from 'deep history' to set the stage for a 'theory by verb' elaborating the many paradoxes of humans' 6,000-year gamble with the Urban Condition and explaining cities' own intrinsic capacity to outrun their own theorizability.

A fascinating historical examination of the Santiago Metro system as a microcosm of Chilean national identity during the twentieth century The Santiago Metro, the largest urban infrastructure project in Chile’s history, was designed in the 1960s in response to rapid urban growth. Despite the upheavals of Salvador Allende’s democratic socialism (1970–1973) and Augusto Pinochet’s military dictatorship (1973–1990), the project survived and is now the largest metro system in South America. What explains its success? How did its meaning shift under democracy and dictatorship? What does its history reveal about struggles for a more just city? Drawing on Chilean and French archives, Andra B. Chastain demonstrates that Chilean-French relations and French financing were crucial to the project’s survival during the Cold War. The Metro’s history also illuminates the contested process of implementing neoliberalism and the unexpected continuities of state planning and visions for a rational city that persisted despite free-market reforms. Most important, this story shows that the Metro came to symbolize the nation and became a critical site where planners, workers, and urban residents contested Chile’s path to modernity.
