Constitutionalist Revolution Day is observed in São Paulo, Brazil, every July 9. This civic holiday commemorates the beginning of the uprising by the paulistas against the government of Getúlio Vargas in 1932. The revolt was sparked by the deaths of four protesting students at Republic Square, leading to an armed uprising aimed at capturing Rio de Janeiro. Although the revolution ultimately failed, it is regarded as a significant event in São Paulo's history. The paulistas sought to compel Vargas to adopt a new constitution and restore state autonomy, reflecting their discontent with his provisional government. Despite the defeat of the revolutionary movement, Vargas later addressed some demands by appointing a new governor and holding elections for a Constituent Assembly. Residents of São Paulo celebrate this day annually, honoring the legacy of the movement and its impact on Brazilian governance.
