The Cold War coup that protected Brazil's coffee oligarchy

Between 1894 and 1930, Brazil was governed by so-called "coffee presidents" - leaders drawn from the planter oligarchies of São Paulo and Minas Gerais, who ruled in the direct interests of the estates that made Brazil the world's largest coffee producer. This arrangement, sometimes referred to as café com leite (coffee with milk), reflected an informal power-sharing agreement between São Paulo's coffee barons and Minas Gerais' dairy and agricultural elite, and it shaped Brazilian politics for decades.

Coffee was central to the country's economic and political structure. Vast fazendas concentrated land and wealth in the hands of a small elite, while the workers who grew and picked the coffee lived under what was known as the colonato system - a semi-feudal arrangement in which labourers were tied to estates, paid partly in kind or through the right to grow subsistence crops between the coffee rows, with little legal standing and almost no access to education, healthcare, or political representation. The system kept workers dependent on landowners and kept landowners in control of both the economy and the political apparatus that supported it.

Brazil's reliance on coffee also made the country vulnerable to the boom-and-bust cycles of global commodity markets. When prices collapsed during the Great Depression, the government responded by buying and burning millions of sacks of surplus coffee to prop up prices - an intervention that protected the planter class but did nothing for the workers or for the broader economy. The economist Celso Furtado, who would later serve as Goulart's first Minister of Planning, analysed this dynamic in his landmark 1959 work Formação Económica do Brasil (translated as The Economic Growth of Brazil), arguing that the coffee cycle perpetuated a pattern of dependency in which the state socialised losses during downturns while allowing profits to remain concentrated in the hands of the elite during booms.

By the early 1960s, that structure was under pressure. Coffee overproduction had destabilised prices once again, rural workers were migrating to cities in growing numbers, and the old model of export-dependent growth was running out of road. In 1961, João Goulart - a rancher from Rio Grande do Sul, a protégé of former president Getúlio Vargas, and a member of the Brazilian Labour Party (PTB) - became president.

Goulart was centre-left, not a communist, despite what his opponents would later claim. His programme, the Reformas de Base (Basic Reforms), was aimed at the structural roots of Brazilian inequality and drew directly on the kind of analysis Furtado had been developing for years. The reforms included breaking up large agricultural estates and redistributing land to peasant farmers, extending labour rights such as minimum wages, union protections, and legal standing to rural workers, and enfranchising illiterate citizens through electoral reform - which, in a country where landowners had historically benefited from keeping their workforce uneducated, was as much an economic threat as a democratic one. Goulart also pushed for nationalisation of key industries and greater state control over foreign capital, as part of a broader effort to reduce Brazil's dependence on commodity exports controlled by a handful of powerful families.

For the coffee oligarchy, these reforms represented an existential challenge. Redistributing land meant redistributing their land, giving workers legal protections meant raising their costs, and extending the vote to the illiterate meant undermining their grip on rural politics. The Estatuto do Trabalhador Rural (Rural Worker Statute), signed into law by Goulart in March 1963, was a particular flashpoint - it extended minimum wage, paid leave, weekly rest, and the right to unionise to agricultural workers for the first time, striking directly at the colonato system and the cheap, captive labour force that coffee production had relied on for generations. Many landowners responded by mass-firing permanent workers and replacing them with temporary day labourers to avoid the new obligations.

On 31 March 1964, the Brazilian military seized power in a coup d'état, overthrowing Goulart's democratically elected government. The takeover had been building for months, with growing coordination between military leaders, conservative politicians, and business interests who saw Goulart's reforms as a step toward communism. The US didn't just look the other way - it actively supported the takeover. The Kennedy and Johnson administrations had already been working to destabilise Goulart's government, and when the coup came, the US launched Operation Brother Sam: a naval task force led by the aircraft carrier USS Forrestal, accompanied by destroyers and oil tankers, was dispatched from Virginia toward the Brazilian coast, while ammunition and fuel shipments were prepared for airlift to São Paulo. In the event, the Brazilian military moved fast enough that the task force was recalled before it arrived, but the intent was unmistakable: had the coup faltered, Washington was prepared to back it directly.

As Vincent Bevins documents in The Jakarta Method, Brazil was one of a series of Cold War interventions in which Washington backed the overthrow of left-leaning governments across the Global South. The pattern repeated in Indonesia in 1965, where a US-supported military purge killed an estimated 500,000 to one million people; in Chile in 1973, where the CIA supported the coup against Salvador Allende that installed Augusto Pinochet; and in Guatemala, Argentina, and elsewhere. The approach was consistent: label a reformist leader as a communist threat, support their removal by military or authoritarian forces, and install a regime more amenable to US strategic and economic interests. The human cost was staggering - mass killings, forced disappearances, political repression, and decades of authoritarian rule affecting millions of people across Latin America, Southeast Asia, and Africa.

In Brazil, the coffee elite, the armed forces, and Washington found common cause. Goulart was forced into exile in Uruguay and later Argentina, where he remained until his death in 1976. The military dictatorship that replaced him lasted 21 years, until 1985, and was marked by censorship, torture of political prisoners, and the systematic suppression of the labour movements and rural organising that Goulart had tried to empower.

The reforms died with his presidency. Brazil's coffee sector did eventually modernise under military rule, but on the terms of large producers - through mechanisation, consolidation, and an expansion of industrial-scale farming, not through redistribution. The concentrated land ownership that Goulart had tried to undo remained largely intact. The workers who had been promised land, rights, and a political voice got none of those things, and the colonato system was replaced not by smallholder farming but by wage labour on ever-larger commercial estates.

Brazil is still the world's largest coffee producer, and the story of who owns that production and who benefits from it runs through everything - from the politics that shaped a continent to the coffee in your cup. It's worth knowing that someone tried to change it, and what it cost them.
