Constitutionalist Revolution Day (São Paulo)

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.

São Paulo is one of the 26 states of the Federative Republic of Brazil and is named after Saint Paul of Tarsus. It is located in the Southeast Region and is bordered by the states of Minas Gerais to the north and northeast, Paraná to the south, Rio de Janeiro to the east and Mato Grosso do Sul to the west, in addition to the Atlantic Ocean to the southeast. It is divided into 645 municipalities. The total area is 248,219.481 square kilometres km², which is equivalent to 2.9% of Brazil's surface, being slightly larger than the United Kingdom. Its capital is the municipality of São Paulo.
