What happened
The Republic was proclaimed by Marshal Deodoro da Fonseca and the army on 15 November 1889, ending the monarchy of Pedro II. The Constitution of 24 February 1891 established a federal presidential republic modeled partly on the United States. It set the vote for literate men over 21, while Article 70 explicitly barred beggars and illiterates from registering to vote, along with enlisted soldiers and members of monastic orders. In a country that was mostly illiterate, this kept the electorate small.
National politics was run by state oligarchies. From the first civilian president, Prudente de Morais (1894), governor of coffee-rich São Paulo, a line of "coffee presidents" drawn mainly from São Paulo and Minas Gerais "gave Brazil little real democracy, because only a select landowning minority was allowed to vote, fraudulent elections were widespread, and regional political bosses had virtual impunity as long as they supported the president in power". The arrangement is remembered as the café com leite ("coffee with milk") alternation between the two states, sustained at local level by coronelismo — rural landowners delivering controlled blocs of votes.
The economy was built on coffee, which by 1900 accounted for more than half of export earnings. When overproduction threatened prices, the three main coffee states signed the Convênio de Taubaté in early 1906; Congress approved it as Decree No. 1,489 of 6 August 1906, and the federal government began buying surplus coffee to hold the price — Brazil's first large state intervention to "valorize" the crop. Coffee wealth drew mass immigration: São Paulo's population rose from 35,000 in 1883 to 350,000 in 1907, and the Amazon rubber boom turned Manaus into a city with electricity and an opera house.
The early Republic also fought internal revolts. In the Canudos War of 1897, the army destroyed a religious settlement in the Bahian backlands led by Antônio Conselheiro; the fourth and final expedition ended in October 1897 with "more than 20,000 dead and the settlement of Belo Monte burned". In the capital, the Vaccine Revolt of 10–16 November 1904 broke out against Oswaldo Cruz's compulsory smallpox vaccination law during a 1904 smallpox epidemic, part of a sanitary campaign that ran alongside prefect Francisco Pereira Passos's demolition-heavy remodeling of Rio. Oswaldo Cruz's program virtually eradicated yellow fever in the capital.
In the 1920s, junior army officers — the tenentes ("lieutenants") — launched a series of uprisings. The first, on 5 July 1922, ended in the "march of the 18 of the Fort" at Copacabana; revolts followed in São Paulo and other states in 1924, and survivors formed the Prestes Column, which marched thousands of kilometres through the interior. The tenentes demanded the secret ballot, an end to electoral fraud, and a stronger central state, but "without a social base of support" and with a "putschist and militarist view of the revolutionary process" they never built a coherent governing project. The collapse of coffee prices in the 1929–30 world crisis, combined with the elites' attempt to install another president, ended the system: Getúlio Vargas, the losing candidate in the 1930 election, led the revolt that put him in power, closing the Old Republic on 24 October 1930.
Where the dispute is
The standard English-language account, repeated in textbooks and tourism-cultural writing, reduces the Old Republic to a café com leite oligarchy that "excluded the people," treats Canudos as a massacre of innocent mystics by the republican State, and reads tenentismo as a progressive prelude to a fairer Brazil. On this reading the period is mainly a story of elite exclusion broken by emergent reformers.
A narrower factual reading, supported by primary and primary-grade sources, agrees the franchise was genuinely restricted — the 1891 Constitution barred illiterates from voting and fraud was routine — but adds that the same decades produced real industrial growth concentrated in São Paulo, mass immigration, the carioca Belle Époque, and the public-health reforms that eradicated yellow fever in Rio. On Canudos, the same sources record both the disproportionate military violence and the movement's specifically anti-republican character: the Proclamation of the Republic changed the central government's view of Conselheiro, whose community came to be seen as a monarchist-restorationist threat.
TDIBr's reading
TDIBr's reading: the Old Republic was neither the cartoon oligarchy of the left textbook nor a golden age of order. The exclusion was real and legally codified — the 1891 Constitution itself denied the vote to illiterates and the poor, in a mostly illiterate country, and fraud and coronelismo made elections a managed ritual. But the period is not reducible to exclusion: coffee-financed immigration and urbanization and the sanitary state-building of Oswaldo Cruz were durable achievements that the "oligarchy excluded the people" framing erases.
Canudos is where the anglophone-left default most clearly misleads. The military assault was disproportionate — a settlement reduced to ruins with over 20,000 dead — and that cost should not be minimized. Yet the popular framing of "the republican State against mystic peasants" omits that Antônio Conselheiro's movement was read at the time as anti-republican and restorationist, a reading the FGV record traces directly to the change in official attitude after the Proclamation of the Republic. Naming both the excess and the movement's anti-republican character is precision, not apology for the army.
The matching myth on the other side is the romance of the tenentes as clean reformers. The same primary record describes them as a putschist officer movement without a coherent project or social base; they helped break the coffee elite's monopoly but were then pushed aside by the victorious oligarchies in 1930. They destabilized the Republic far more than they reformed it, and they set the stage for Vargas rather than for democracy.
Why it matters internationally
The Old Republic is where several enduring features of Brazil were set. The federal coffee price-support scheme of 1906 was an early model of commodity-state intervention that anglophone economists still cite; the country's dependence on a single export and its vulnerability to the 1929–30 price collapse prefigured later commodity cycles, including the China-driven boom of the 2000s. The literacy requirement that kept most Brazilians off the rolls until 1985 shaped a long, slow, contested path to mass suffrage that still informs debates over the legitimacy of Brazil's institutions. And the 1930 revolt that ended the Republic — an armed seizure of power led by an election loser — opened the Vargas era and the pattern of military intervention in politics that runs through the twentieth century. For a reader trying to understand modern Brazil, the Old Republic is the origin point of its commodity economy, its uneven democracy, and its recurring temptation to settle political deadlock by force rather than the ballot.
