 This was followed by a large demonstration on March 19, where a conservative group marched on Praça da Sé, São Paulo, in a demonstration called "March of the Family with God for Freedom" against Goulart and his policies.The friction between the military and Goulart boiled over with his intervention in a revolt by sailors of the Brazilian Navy led by José Anselmo dos Santos, historically known as Cabo Anselmo, and later exposed as an agent provocateur.On March 25, 1964, nearly 2,000 sailors assembled in Rio de Janeiro, petitioning for better living conditions and pledging their support for Goulart's reforms.
