In this pathbreaking book, Kenny Cupers forcefully shows how our understanding of architectural modernism in Germany benefits from placing it in a larger postcolonial framework. Theoretically sophisticated and empirically rich, The Earth That Modernism Built skillfully connects metropolitan Germany, Namibia, and the Prussian borderlands, thus revealing how developments in architecture and urban planning were bound up with concepts of Lebensraum and imperial notions of space. Eye-opening. - Sebastian Conrad, Free University of Berlin, author of What Is Global History? The Earth That Modernism Built revisits one of the most fundamental presuppositions of modernism, that reshaping the built environment will transform humanity and engineer a new world. Ambitious in scope, while providing nuanced accounts of significant, situated projects, both familiar and relatively unknown, this kaleidoscopic study reveals how environmental and geopolitical thinking have been written into modern architecture and planning by way of racialized discourses regarding land, soil, and settlement. Through this astute shift in perspective on the recent outpouring of studies tracing the colonial histories of modernity, Cupers offers instead an incisive and previously overlooked history of architectural modernisms coloniality. - Sheila Crane, University of Virginia, author of Mediterranean Crossroads: Marseille and Modern Architecture
