According to the then German ambassador to Brazil, Karl Ritter, there were explicit guidelines that the party should not interfere in Brazil's internal affairs. The party operated in Brazil from 1928 to 1938, without being interfered with by the Brazilian government, then led by Getúlio Vargas. In the last year, 1938, after the establishment of the Estado Novo dictatorship, the Nazi party and all other foreign political associations were declared illegal.
