Constitutionalist Revolution of 1932

The Constitutionalist Revolution of 1932, known in Portuguese as the Revolução Constitucionalista, was an armed uprising in São Paulo against the provisional government of Getúlio Vargas. After the Revolution of 1930 brought Vargas to power and suspended the existing constitutional order, many political leaders in São Paulo demanded the restoration of constitutional government, civil liberties, and greater state autonomy. Tensions intensified after the deaths of four young demonstrators—Martins, Miragaia, Dráusio, and Camargo—during a protest on May 23, 1932; their initials gave rise to the movement’s famous acronym, MMDC.", "The revolt began on July 9, 1932, with São Paulo forces seeking to compel Vargas to convene a constitutional assembly. Although the movement received considerable popular support and mobilized volunteers, donations, industrial production, and propaganda, it lacked sufficient military backing from other states and was defeated on October 2. Its political impact nevertheless proved significant: Vargas later called a constitutional assembly, leading to Brazil’s 1934 Constitution. In São Paulo, July 9 became a powerful symbol of civic resistance and constitutionalism, and it was established as a state holiday in 1997. The date is observed in São Paulo rather than as a nationwide Brazilian public holiday; in 2026, it falls on Thursday, July 9.

Celebrations of the Constitutionalist Revolution of 1932 in São Paulo typically combine civic commemoration with military and historical remembrance. Ceremonies often take place at the Obelisk and Mausoleum to the Heroes of 1932 in Ibirapuera Park, São Paulo, where officials, veterans’ associations, civic organizations, and members of the public pay tribute to those who died. Wreath-laying ceremonies, flag raisings, speeches, military honors, and memorial services are common, while museums and cultural institutions may organize exhibitions, lectures, and educational programs about the uprising and the 1930s.", "Many cities across São Paulo state hold civic parades, historical reenactments, school presentations, concerts, and displays of the state flag and MMDC symbols. Families may visit memorials, historical sites, and local museums, while television, newspapers, and cultural organizations revisit the revolution’s role in the development of Brazilian constitutional life. Unlike religious festivals or food-centered holidays, July 9 has no single traditional dish or universally prescribed meal; regional restaurants and households may simply mark the day with São Paulo cuisine and family gatherings. Common commemorative expressions include “Viva o 9 de Julho!” and “Viva a Revolução Constitucionalista!”, often used alongside messages honoring democracy, civic participation, and the memory of the 1932 movement.
