Chicago's transformation from a contested Indigenous trading post to one of America's greatest cities is traced through conflict, commerce, and construction. The defeat of Black Hawk and the forced removal of the Potawatomi cleared the way for settler expansion and opened fertile land to exploitation. Infrastructure investments like the Illinois-Michigan Canal and the expanding railroad network established Chicago as the dominant commercial hub of the mid-continent. Revolutionary technologies like the steam-powered grain elevator, the Union Stockyard, and barbed wire each reshaped the industries that fed the city's explosive growth. The Great Fire of 1871 destroyed the old Chicago but cleared the path for a modern, rebuilt city with taller structures and stricter standards. The World's Columbian Exposition of 1893 marked the triumphant culmination of this journey, presenting Chicago's achievements to the world while concealing the ecological and human costs beneath its gleaming surface.

Chicago's rise from frontier outpost to industrial metropolis.

Behind Chicago's headline rise lay a dense web of secondary forces—personal, intellectual, and economic—that made the city's growth possible. Cronon's own journey from childhood repulsion to mature appreciation of Chicago frames a narrative of shifting perceptions about what separates city from country. Intellectual frameworks like Von Thünen's agricultural zone theory gave scholars tools to understand how urban markets generate economic activity in surrounding rural areas. Practical innovations like the telegraph, McCormick's reaper, and the refrigerated railcar each reshaped a different sector of Chicago's economy. New commercial institutions—from commission merchants to wholesale lumber markets to mail-order catalogs—wove city and hinterland into an ever-tighter economic fabric. Chicago's eventual victory over St. Louis as the regional trade capital sealed its role as the undisputed gateway between the established East and the developing West.

Cronon concludes that viewing Chicago as humanity's conquest of nature obscures the city's fundamental dependence on the nonhuman world.

Beneath Chicago's rise lay a series of pivotal decisions and revelations that transformed both the land and the people who depended on it. Cronon's personal intellectual turning points—recognizing that his love of the countryside is inseparable from his opposition to Chicago—set the philosophical stakes for the entire book. The commodification of the prairie, the corruption of grain markets, and the near-extinction of the bison each reveal how market forces reshaped the natural world in ways that proved difficult or impossible to reverse. Industries that seemed to promise endless growth—bison hunting, white pine logging, and open-range cattle driving—collapsed under the weight of their own exploitation. New institutions, technologies, and immigrant labor networks filled the gaps left by these collapses, keeping Chicago's engine running through the second half of the century. The World's Fair of 1893 became the ultimate turning point, a moment when Chicago celebrated its extraordinary achievements while the ecological and human costs of its rise remained carefully hidden from public view.
