From 23 November to 27 November 1935, a Brazilian Communist Party–backed attempted military coup was initiated in Rio Grande do Norte. Its capital, Natal, was shortly governed by a junta until it was defeated. Likewise, movements in Recife and Rio de Janeiro followed. There, the encounters between troops were especially bloody and several were left dead. The aftermath was severe. Historians Boris and Sergio Fausto state, "it opened the way for far-reaching repressive measures and for an escalation of authoritarianism." The PCB in particular and the political left-wing in general were oppressed under the authority of the executive branch and the procurement of the National Congress. For instance, the National Commission for Stopping Communism (or the National Commission for the Repression of Communism) was created in January alongside more government organs, such as the National Security Tribunal [] created in October, to investigate the 1935 uprising, though the TSN ended up becoming a permanent organization until 1945. Congress was sieged by police in March ending with the arrest of several pro-National Liberation Alliance, a leftist front, assemblymen, and many communists were imprisoned and exiled. The 1934 constitution essentially existed only "de jure" as it was ignored by the states of emergency, police actions, and the anti-communist climate. The importance of the revolt is because, in its aftermath, it saw the first speculation of Vargas initiating a self-coup.
