  1. 1One crash, one collapsed republic: Brazil in 1930
  2. 2Vargas in power: stability, centralization — and who paid the price
  3. 3Whose Brazil? Migration, women, marginalised groups and culture

In October 1929, the Wall Street Crash sent shockwaves across the world. Nowhere in Latin America felt it harder than Brazil.

Brazil's economy ran on one crop: coffee. By 1929, coffee made up around 70% of Brazil's export earnings. When world demand collapsed, so did the price of coffee — and so did the government's ability to keep propping it up.

Cause and consequence: from crashing prices to a collapsed republic: This is a textbook case of cause and consequence. An economic shock (collapsing coffee prices) triggered a political crisis (the fall of the Old Republic) within a single year — 1929 to 1930.

Before the Crash, Brazil was ruled under the 'Old Republic' (1889–1930). Power rotated between two elite groups: coffee growers from São Paulo and dairy farmers from Minas Gerais. Historians nickname this the café com leite system. It was never democratic in a real sense — it relied on rigged local elections controlled by state governors.

The Depression broke this system's economic base. Coffee elites could no longer buy loyalty and stability with export wealth, and ordinary Brazilians — hit by unemployment and falling wages — had less patience for a political system that only served planters.

  • 1929 — Coffee prices collapse as US demand dries up; Brazil's main export income vanishes almost overnight.
  • 1930 election — São Paulo's candidate, Júlio Prestes, is declared the winner over Getúlio Vargas in a vote most historians agree was manipulated.
  • October 1930 — Vargas's allies, the Liberal Alliance, launch an armed revolt. The army refuses to defend the old order.
  • November 1930 — Vargas is installed as provisional president. The Old Republic is finished.
Don't just say 'the economy collapsed' — trace the chain: For Paper 3, always show the mechanism: crash → coffee price collapse → Old Republic's elite bargain breaks down → contested election → revolt → new regime. Examiners reward a clear causal chain, not a vague link.

Getúlio Vargas ruled Brazil from 1930 to 1945, but his grip on power tightened in stages. He began as a 'provisional president', then as an elected leader under a new 1934 constitution, and finally as an outright dictator.

1

1930–34: Provisional rule

Vargas rules by decree, appoints loyal 'interventores' to run states instead of elected governors — smashing the old regional oligarchies' independence.

2

1934: New constitution

A Constituent Assembly writes a new, more centralized constitution. Vargas is elected president by that assembly (not by direct popular vote).

3

1937: The 'Estado Novo' self-coup

Citing a forged communist takeover plot (the 'Cohen Plan'), Vargas cancels the 1938 election, rules by decree, and imposes an authoritarian corporatist constitution.

Provisional → Constitutional → 'New State' dictatorship: three years, three regimes, one man.

This was a huge shift in political power. Authority moved away from regional coffee-and-dairy oligarchies and concentrated in a strong federal state — and, within that state, increasingly in Vargas himself.

Vargas also faced real opposition from multiple directions, showing his rule was contested, not simply accepted.

Opposition from the right / old elites

  • 1932 Constitutionalist Revolution — São Paulo's elite rebel against losing state autonomy and demand a new constitution; defeated after 3 months of fighting, but Vargas concedes the 1934 constitution.
  • Integralistas (Brazilian fascist-style movement, led by Plínio Salgado) initially back Vargas against the left, then turn on him once Estado Novo sidelines them — failed uprising in 1938.

Opposition from the left

  • 1935: the Aliança Nacional Libertadora (ANL), a left-wing alliance linked to the Communist Party under Luís Carlos Prestes, launches a failed uprising.
  • The 'Intentona Comunista' is crushed and used to justify mass arrests and repression — including the deportation of activist Olga Benário Prestes to Nazi Germany, where she later died in a concentration camp.
Labour rights: reform, but on the state's terms: Vargas's reforms earned him the nickname 'father of the poor' (pai dos pobres). This is often called 'state corporatism': benefits granted from above, in exchange for obedience, not independent worker power.

What workers gained

  • A Ministry of Labour
  • Labour courts
  • A minimum wage (1940)
  • Pension institutes for many categories of urban workers

What the state controlled

  • Unions were brought under strict state control
  • Strikes were effectively banned
Watch the gap: who was actually covered?: These labour protections mostly applied to formal, urban, industrial workers. Rural laborers — the majority of Brazil's workforce — were excluded from almost all of it. Keep this distinction sharp: it is central to evaluating how far 'reform' really reached.

The Depression reshaped where Brazilians lived and how they experienced daily life — but very unevenly.

As coffee estates cut jobs and Europe's subsidized immigration schemes dried up, migration patterns shifted. More people moved within Brazil itself: from the drought-hit Northeast (the sertão) toward São Paulo and the industrializing south, and from countryside to city generally.

  • Demography and standard of living — urban populations in São Paulo and Rio de Janeiro grew quickly. Formal-sector workers gained new protections (minimum wage, pensions), but the majority outside that sector — rural laborers, informal workers, recent migrants — saw little improvement and often faced real hardship.
  • Experiences of women — women increasingly entered urban factory work, especially textiles, usually for the lowest pay. A major political gain came in 1932: the new Electoral Code granted women's suffrage, and Brazilian women voted for the first time in the 1933 Constituent Assembly election, a goal feminist campaigners like Bertha Lutz had pushed for through the 1920s.
  • Experiences of marginalised groups — Afro-Brazilians remained largely shut out of the new formal-sector labour protections, concentrated instead in informal and rural work. Indigenous peoples stayed under the paternalist, assimilationist policy of the state's Indian Protection Service (SPI, founded 1910), which continued largely unchanged. Northeastern migrants ('retirantes') fleeing drought often faced discrimination in the southern cities they moved to.
  • Impact on culture and the arts — the Estado Novo actively built a state-approved national identity, called 'brasilidade'. Samba and Carnival were embraced and organised (via official samba schools) as symbols of the nation. A new propaganda ministry (DIP, 1939) controlled radio and press, broadcasting programmes like 'Hora do Brasil' to promote Vargas directly into people's homes.
Same event, very different experiences: 'Social impact' was not one experience — it was many, split sharply by race, region, and job.

An urban, male, factory worker in São Paulo in 1936

  • Likely saw real gains
  • A minimum wage
  • A pension fund
  • Maybe a state-approved union representing him

A Black rural laborer in the Northeast, or an Indigenous person under SPI supervision

  • Saw almost none of this

This unevenness matters for the concept of significance. If you only describe the labour laws, you overstate how much actually changed for most Brazilians. A stronger answer weighs formal-sector gains against the much larger population left out.

GroupMain change 1930–39Limits of that change
Urban industrial workersMinimum wage, labour courts, pensions (IAPs)Unions state-controlled; strikes banned
Women (urban, literate)Suffrage won 1932; more factory jobsLowest pay; 'protective' laws also restricted them
Rural / Afro-Brazilian workersLargely excluded from new lawsNo minimum wage, no pension access
Indigenous peoplesNo policy changeStill under paternalist SPI assimilation model
