About Jânio Quadros
Jânio da Silva Quadros (Portuguese: [ˈʒɐ̃niu dɐ ˈsiwvɐ ˈkwadɾus]; 25 January 1917 – 16 February 1992) was a Brazilian lawyer and politician who served as the 22nd president of Brazil from 31 January to 25 August 1961, when he resigned from office. He also served as the 24th and 36th mayor of São Paulo, and the 18th governor of the state of São Paulo. Quadros was known for his populist style of government and eccentric behavior. As president, he focused on economic reform and attempted to root out corruption. He also pursued an independent foreign policy, trying to balance Brazil's relations between the United States and the Eastern Bloc. Although he was elected by a huge margin, his term was marked by uncertainty and political instability, culminating in his resignation. That unexpected move caused a national crisis, with the presidency being assumed by João Goulart after the Legality Campaign. Quadros easily won, and his 15.6% margin of victory would be the largest margin for a presidential election held by popular vote until Fernando Henrique Cardoso won by 27% in 1994. When Quadros took office on January 31, 1961, it marked the first time since Brazil had become a republic in 1889 that an incumbent government peacefully transferred power to an elected member of the opposition. Despite that success, the separate race for vice president was won by João Goulart, Lott's running mate.
