In 1935, Plínio Salgado released his political manifesto at the stage of Theatro Municipal creating the Brazilian Integralist Party (Partido Integralista Brasileiro). Several people reacted against it in a big confront between supporters of Plínio and opposition parties. Turmoils, fights, cops, prisons, gun shots, and murders happened in the city because of the event.
