Republic of Brazil
The Old Republic (1889–1930)
Pedro II was deposed on November 15, 1889, by a Republican military coup led by General Deodoro da Fonseca, who became the country's first de facto president through military ascension. The country's name became the Republic of the United States of Brazil (which in 1967 was changed to Federative Republic of Brazil.). Two military presidents ruled through four years of dictatorship amid conflicts, among the military and political elites (two Naval revolts, followed by an Federalist revolt), and an economic crisis due the effects of the burst of an financial bubble, the encilhamento.
From 1889 to 1930, although the country was formally a constitutional democracy, the First Republican Constitution, created in 1891, established that women and the illiterate (then the majority of the population) were prevented from voting. The presidentialism was adopted as the form of government and the State was divide into three powers (Legislative, Executive and Judiciary) "harmonics and independents of each other". The presidencial rule was fixed in four years, and the elections became direct.
After 1894, the presidence of republic was occupied by coffee farmers (oligarchies) from São Paulo and Minas Gerais, alternately. This policy was called política do café com leite (coffee and milk policy). The elections for president and governors was ruled by the Política dos Governadores (Governor's policy), in which they had mutual support to ensure the elections of some candidates. The exchanges of favors also happened among politicians and big landowners. They used the power to control the votes of population in return for favors (this was called coronelismo).
Between 1893 and 1926 several movements, civilians and military, shook the country. The military movements had their origins both in the lower officers' corps of the Army and Navy (which, dissatisfied with the regime, called for democratic changes) while the civilian ones, such Canudos and Contestado War, were usually led by messianic leaders, without conventional political goals.
Internationally, the country would stick to a course of conduct that extended throughout the twentieth century: an almost isolationist policy, interspersed with sporadic automatic alignments with major western powers, its main economic partners, in moments of high turbulence. Standing out from this period: the resolution of the Acreanian's Question and the tiny role in the World War I (basically limited to the anti-submarine warfare).
Populism and development (1930–1964)
After 1930, the successive governments continued industrial and agriculture growth and development of the vast interior of Brazil. Getúlio Vargas led a military junta that had taken control in 1930 and would remain ruling from 1930 to 1945 with the backing of Brazilian military, especially the Army. In this period, he faced internally the Constitutionalist Revolt in 1932 and two separate coup d’état attempts: by Communists in 1935 and by local Fascists in 1938.
A democratic regime prevailed from 1945–64. In the 1950s after Vargas' second period (this time, democratically elected), the country experienced an economic boom during Juscelino Kubitschek's years, during which the capital was moved from Rio de Janeiro to Brasília.
Externally, after a relative isolation during the first half of the 1930s due to the effects of the 1929 Crisis, in the second half of the 1930s there was a rapprochement with the regimes of Italy and Germany. However, after the fascist coup attempt in 1938 and the naval blockade imposed on these two countries by the British navy from the beginning of World War II, in the decade of 1940 there was a return to the old foreign policy of the previous period.
