Background
- Populism in Latin America emerged after the Great Depression (1929), when traditional elites failed to protect workers and farmers from economic collapse.
- New leaders used nationalism, social reform, and mass mobilization to gain support from the working class.
- Both Juan Domingo Perón in Argentina and Getúlio Vargas in Brazil promised to modernize their countries, reduce inequality, and defend national sovereignty from foreign control.
- Their regimes mixed authoritarianism with charismatic leadership, combining genuine social reform with political repression.
Authoritarianism
- Authoritarianism is a political system characterized by the consolidation of power in a single leader or small group, limited political pluralism, repression of dissent, and little to no accountability to the public.

The 1930 Revolution in Latin America (Brazil)
Background
- Before 1930, Brazil was ruled by a political system known as the Old Republic (1889–1930).
- Power was shared between wealthy landowning elites from São Paulo (coffee producers) and Minas Gerais (dairy producers).
- This arrangement was called “café com leite” politics (“coffee with milk”), as it excluded most of the population from politics.
- The Great Depression (1929) caused global coffee prices to collapse, destroying Brazil’s export economy.
- Middle-class reformers, military officers, and regional leaders began to challenge the old system.
Causes of the Revolution
- Economic crisis: Falling coffee prices led to unemployment and loss of government income.
- Social discontent: Workers and peasants demanded reforms and better living conditions.
- Political exclusion: Only elites had power; the middle and working classes were left out.
- Regional rivalry: Other states resented São Paulo’s dominance in politics.
- Trigger event: When Washington Luís (president) chose another São Paulo politician as his successor in 1930, opposition formed behind Getúlio Vargas of Rio Grande do Sul.
Main Events
- Vargas led a coalition of disgruntled politicians, military officers, and young nationalists.
- His forces launched a revolt in October 1930, quickly gaining control of major cities.
- The army refused to support the old regime, forcing President Washington Luís to resign.
- On November 3, 1930, Vargas became provisional president, marking the end of the Old Republic.
Results and Significance
- Vargas began a period of modernization and centralization in Brazil.
- The revolution ended the rule of regional coffee elites and opened politics to new social groups, including workers and the middle class.
- Vargas introduced labor reforms, promoted industrialization, and created a stronger national identity.
- The 1930 Revolution is often seen as the turning point from an agricultural oligarchy to a modern, urban, industrial Brazil.
- It also inspired other Latin American countries to question elite dominance and demand economic reform.
Ideology
Perón:
- Promoted Justicialismo (social justice), a mix of nationalism, labor rights, and Catholic values.
- Opposed communism and capitalism, calling his model the “Third Position.”
- Focused on workers’ dignity, social unity, and Argentina’s independence from foreign powers.
