The Arc of Formality in Twentieth-Century Rio de Janeiro

Rio de Janeiro began the twentieth century as capital of a nation that had ended slavery and monarchical rule only in 1888-89. In the new republic, coffee exports and early industrialization concentrated in São Paulo. Rio drew people recently out of slavery and/or escaping the struggling sugar economy of Northeast to irregular subdivisions and informal favelas. As the century moved forward, both the Vargas regime (1930-54, 1950-54) and the military dictatorship (1964-85) promoted formal urban development with land titles and services while the national capital and much of the bureaucracy moved to Brasilia after 1960 and Rio’s limited industrial base corroded. The urban population kept growing, driving a return of informal development as military rule ceded to re-democratization. Favelas, informal subdivisions, and social marginality spread again as criminal enterprises linked to the global drug economy brought limited prosperity and rising violence to the metropolis—contradictions that hosting the 2014 World Cup and the 2016 Olympics could not resolve.
