The history of the city in twentieth-century Latin America can be seen as a long contest over the exercise of urban public space. While the nature of this space is often less physical than it is social and situational, the struggle between different elements of the city to manipulate its politics and control its daily life has often been violent, leaving deep imprints in the collective memories of places as culturally and physically diverse as Mexico City, Buenos Aires, Havana, Bogotá, and Rio de Janeiro.

If approached from the perspective of contested space, the urban milieu offers an intriguing site for the historian interestedin exploring changing relations of power, class conflict, opposing visions of the future, breakdowns of social order, gendered spaces, health and disease, visual culture, spectacle and symbolic codes, and ultimately, the creation of community. Yet until the 1980s, most Latin American historians who were interestedin these themes confined their studies to the countryside. As late as 1975, Jorge Hardoy (1975:44) could write that “the urban history of the second half of the nineteenth century and the early decades of the twentieth is virtually unknown, in spite of the extremely rich material left to us by innumerable travelers, scientists, and men of state.” While historians and social scientists working from the 1950s through much of the 1970s delineated the complex relations between peasant villages and national states, the ideologies of rural rebellion, and the sources of identity and community in a countryside transformed by the demands of export capital, cities in twentieth-century Latin America were accorded secondary treatment, sometimes at the level of popular anecdotal narratives.
