Fourth Brazilian Republic
The Fourth Brazilian Republic was the period of Brazilian history from 1946 to 1964 characterized by parliamentary and presidential contests after the fall of Getúlio Vargas and before the 1964 Brazilian coup d'état. It encompassed the promulgation of the 1946 Brazilian Constitution of 1946, the relocation of the national capital to Brasília, intense rivalry among the Social Democratic Party (Brazil, 1945–1965), the National Democratic Union (Brazil), and the Brazilian Labour Party (historical), and culminating crises involving Juscelino Kubitschek, João Goulart, and elements of the Brazilian Armed Forces. The era intersected with global events such as the Cold War, the Non-Aligned Movement, and regional developments including the Cuban Revolution.
Background and Establishment
The republic emerged from the 1945 deposition of Getúlio Vargas after World War II controversies including the Estado Novo period, marked by repression and industrial policy debates involving the Brazilian Institute of Geography and Statistics and the Ministry of Labor. The 1946 Brazilian Constituent Assembly (1946) drafted the new charter restoring civil liberties, re-legalizing parties such as the Communist Party of Brazil (historical), and setting the framework for contested elections including the 1945 and 1946 presidential campaigns featuring figures tied to the Argentine Revolution (1943–46) and postwar regional alignments. Domestic politics were shaped by urban elites in São Paulo, rural oligarchies in Minas Gerais, and labor movements organized around leaders allied with the Brazilian Labor Confederation and the old Vargas networks.
Political Structure and Key Institutions
The 1946 constitution recreated the separation of powers among the executive led by the president, a bicameral legislature comprising the Chamber of Deputies (Brazil) and the Federal Senate (Brazil), and a judiciary that invoked the Supreme Federal Court (Brazil). Federal institutions included the Ministry of Finance (Brazil), the National Bank for Economic and Social Development (BNDES) precursor organizations, and the Electoral Justice of Brazil overseeing contested ballots such as the 1950 and 1955 races. Political parties like the Brazilian Socialist Party (1947) and the Christian Democratic Party (Brazil) competed with labor-oriented groups while regional machines in Goiás and Rio Grande do Sul mediated clientelism and patronage through municipal councils and state legislatures.
Governments and Major Presidencies
Presidents during the period included Eurico Gaspar Dutra (1946–1951), whose policies reflected alliances with the United States Department of State and industrialists in São Paulo State Federation of Industries; Getúlio Vargas returned in 1951–1954 amid confrontations with the National Congress of Brazil, military officers sympathetic to populism, and journalists linked to newspapers like O Estado de S. Paulo and Diário Carioca. After Vargas's suicide, Café Filho and interim figures presided before Juscelino Kubitschek (1956–1961) advanced the Plano de Metas and inaugurated Brasília with architects such as Oscar Niemeyer and planners like Lúcio Costa. The presidency of Jânio Quadros in 1961 ended abruptly, precipitating the 1961 parliamentary solution and the 1961–1964 tenure of João Goulart, whose reform proposals clashed with conservative blocs including elements of the Brazilian Navy and the Army of Brazil, setting the stage for the 1964 coup supported by sectors of the National Mobilization.
Economic Policies and Social Changes
Economic strategies alternated between import substitution industrialization advocated by technocrats in the Ministry of Finance (Brazil) and export-oriented policies tied to coffee elites in Minas Gerais and São Paulo. Industrialization under Vargas and Kubitschek stimulated steelworks like Companhia Siderúrgica Nacional and automotive investment involving Volkswagen do Brasil and Ford Brazil, while public works in Brasília mobilized construction firms and planners. Social legislation expanded through labor statutes originating in the Vargas era, union activity associated with the General Confederation of Workers strengthened urban working-class organizations, and rural reform debates engaged landless peasants and regional oligarchs such as those in Northeast Brazil and Paraíba. Inflationary cycles, fiscal deficits, and foreign credit negotiations with institutions like the International Monetary Fund and trade partners in Argentina and United States shaped policy responses.
Opposition, Repression, and Human Rights
Political opposition ranged from constitutionalist conservatives linked to the National Democratic Union (Brazil) to leftist activists in the Brazilian Communist Party (historical) and the Brazilian Socialist Party (1947). Repressive actions included police operations by state-level security forces, interventions invoking emergency powers, trials before counsels influenced by military officers from the Brazilian Army and naval detachments, and censorship campaigns affecting newspapers such as Correio da Manhã. Human rights concerns involved detentions, political exiles to countries like Uruguay and Argentina, and clashes between labor organizers and rural militias in regions including Sergipe and Pernambuco.
End of the Fourth Republic and Transition to Military Rule
The collapse culminated with the 1964 Brazilian coup d'état, when military commanders from the Army of Brazil and allied civilian sectors deposed João Goulart, invoking fears of communist influence after the Cuban Revolution and amid Cold War dynamics involving the United States Department of Defense and diplomatic actors in Washington, D.C.. The coup installed a succession of military presidents beginning with Humberto de Alencar Castelo Branco and led to institutional acts that dismantled party structures such as the Brazilian Labour Party (historical) and reconfigured the political order into the Military dictatorship in Brazil (1964–1985), closing the Fourth Republic era and initiating a new authoritarian phase involving structural reforms, press restrictions, and international alignments.
