Ruy Barbosa

Ruy Barbosa de Oliveira (5 November 1849 – 1 March 1923), also known as Rui Barbosa, was a Brazilian polymath, diplomat, writer, jurist, and politician.

He was a prominent defender of civil liberties who called for the abolition of slavery in Brazil, Barbosa represented Brazil in the second Hague convention, argued for Brazil's participation in World War I on the side of the Allies, and personally ordered the destruction of all government records pertaining to slavery while he was Minister of Finance.

He was forced into exile during the presidency of Floriano Peixoto, as his economic policies while he was finance minister paved the way for a disaster in the Brazilian economy. After exile, Barbosa would run an extremely memorable campaign for the presidency, though it ultimately failed. Provided by Wikipedia
