In Brazil, four students are shot and killed during a manifestation against the Brazilian dictator Getúlio Vargas, which resulted in the outbreak of the Constitutionalist Revolution several weeks later.

Brazil, officially the Federative Republic of Brazil, is the largest country in South America. It is also the world's fifth-largest country by area and the seventh-largest by population, with over 212 million people. The country is a federation composed of 26 states and a Federal District, which hosts the capital, Brasília. Its most populous city is São Paulo, followed by Rio de Janeiro. Brazil has the most Portuguese speakers in the world and is the only country in the Americas where Portuguese is an official language.

Getúlio Dornelles Vargas was a Brazilian lawyer and politician who served as the 14th and 17th president of Brazil, from 1930 to 1945 and from 1951 until his suicide in 1954. Due to his long and controversial tenure as Brazil's provisional, constitutional, dictatorial and democratic leader, he is considered by historians as the most influential Brazilian politician of the 20th century.

The Constitutionalist Revolution of 1932 is the name given to the uprising of the population of the Brazilian state of São Paulo against the Brazilian Revolution of 1930, when Getúlio Vargas assumed the nation's presidency. Vargas was supported by the people, the military and the political elites of Minas Gerais, Rio Grande do Sul and Paraíba. The movement grew out of local resentment over Vargas' rule-by-decree, unbound by a Constitution, in a provisional government. The 1930 Revolution also affected São Paulo by eroding the autonomy that Brazilian states enjoyed during the term of the 1891 Constitution and preventing the inauguration of the governor of São Paulo, Júlio Prestes, who had been elected president of Brazil in 1930, while also simultaneously overthrowing President Washington Luís, who was governor of São Paulo from 1920 to 1924. These events marked the end of the First Brazilian Republic.
