Brushing aside objections from human rights groups, and with the support of President Jair Bolsonaro, on Thursday some military bases began commemorations of the March 31, 1964 coup that launched 21 years of military rule in Brazil.
Brazil's Southeast military command, led by General Luiz Baptista Pereira, held a commemoration ceremony in São Paulo.
The order of the day read in the base called March 31, 1964 a "symbolic episode" in the Armed Forces' support for the "legitimate aspirations" of Brazilian people.
"The Brazilian people defended democracy together with their uniformed citizens" that day, it read. "With Brazilian families alarmed and facing great disorder, the escalation toward communism was interrupted."
With rifles on their shoulders, soldiers sang Brazil's national anthem and paraded.
Bolsonaro, a former Army captain who waxes nostalgic for the 1964-1985 military regime, caused a commotion in Brazil when he asked the Defence Ministry to organise "due commemorations" on March 31, a day historians call a coup that began the dictatorship, which supporters call a "military government."
Brazil's Federal Prosecutor's Office strongly criticised Bolsonaro's move, saying that under international criminal law Brazil's dictators "had committed crimes against humanity." Several civic groups announced that they were organiaing protests throughout the country.
