In 1932, Brazil experienced a period in which the Vargas regime governed without a constitution that formally delineated the powers of the President or that made clear the
separation of powers between the National Congress, the Legislature, and municipal councils. In reaction, the Paulistas began to move against the Vargas dictatorship, and students prepared a series of demonstrations, which broke out across the capital in a climate of growing revolt on 23 May of that year. The Revolutionary League, an organization favorable to the regime of
Getúlio Vargas was located near the Republic Square. A group of students tried to invade the pro-government League, which resisted with force resulting in the death of four students, Martins, Miragaia, Camargo and Dráusio died - three of them during the confrontation, and the fourth shortly afterward. A fifth student, Orlando Alvarenga de Oliveira, was injured during the fight did not have his name immediately associated with the movement since he died three months later on 12 August, 1932. Following the episode of Republic Square, an intense campaign of voluntary enlistment throughout the state commenced on July 9, 1932, culminating in the 1932 Constitutionalist Revolution. The initials of Martins, Miragaia, Camargo and Dráusio, M.M.D.C, were used to represent a secret civil organisation which, among other activities, offered military training to the Paulista guerrillas. ==M.M.D.C.A.==
