Answer: Getúlio Vargas "pai dos pobres". Internationally considered a dictator and his regime "Estado Novo" (New State) dictatorship, sometimes filo-fascist or fascist. However, Brazilians call him "the Father of the Poor". That is a small paradox.
Explanation: Vargas role in history of Brazil is quite complex. First, he was a temporary president (1930-34) who governed by means of his decrees, then he was elected president and became a legitimate president (1934-1937), then he did coup d´etat (1937), abolished democratic constitution and established a dictatorship (1937-1945). After the WW II there was a short period without Vargas and then again Vargas presidency in almost democratic conditions (so-called IIIrd republic, 1945-64).
