He prepared a memorial submitted in 1894 and remained in Washington until the award. On 5 February 1895, President Grover Cleveland accepted the river boundary claimed by Brazil. Rio Branco’s assignment was a special arbitration mission.","Born in Rio de Janeiro in 1845, he was the son of the statesman José Maria da Silva Paranhos, the Visconde do Rio Branco. The son studied law, collected historical and geographical material, served in the legislature, and became consul at Liverpool. His own title of baron, granted in 1888, distinguished him from his father, the viscount.","After the Washington award, Rio Branco lived in Paris and later handled Brazil’s boundary case with France before Swiss arbitration. Domício da Gama, who had worked with him on the American mission, assisted him again. A posting to Berlin preceded his appointment as Brazilian foreign minister in 1902. He held that office until his death in 1912."],"id":"global:person-2ceb2e3a6c13596ec41a0402","identifiers":{},"identityScope":"global","legacyPersonIds":[],"legacyUrl":"https://chanceries.org/diplomat-723f95f1fa62311cce8a.html","name":"José Maria da Silva Paranhos Júnior","notes":[],"paragraphSources":[["rio-bio","rio-award"],["rio-bio"],["rio-bio"]],"profileUrl":"diplomat-723f95f1fa62311cce8a.html","relatedEvents":[],"relatedPeople":[{"name":"Domício da Gama","note":"Worked with Domício da Gama on the Washington arbitration mission and later at Berne.","profileUrl":"diplomat-a3edf74095f9b228a07a.html","sourceIds":["rio-bio"],"targetId":"brazil:domicio da gama","type":"worked_with"}],"relationships":[{"note":"Worked with Domício da Gama on the Washington arbitration mission and later at Berne.","sourceIds":["rio-bio"],"targetId":"brazil:domicio da gama","type":"worked_with"}],"researchStatus":"reviewed","reviewedOn":"2026-11-01","revision":"800ddaa2a4ab0ed2","sources":[{"accessedOn":"2026-11-01","date":"","id":"rio-bio","locator":"Early life; Missão especial nos Estados Unidos; Questão do Amapá; Ministério das Relações Exteriores","publisher":"Fundação Getulio Vargas, Atlas Histórico do Brasil","title":"Barão do Rio Branco","type":"scholarly","url":"https://atlas.fgv.br/verbetes/barao-do-rio-branco"},{"accessedOn":"2026-11-01","date":"","id":"rio-award","locator":"Document 1, award issued in Washington, 5 February 1895","publisher":"U.S. Department of State, Foreign Relations of the United States","title":"Award of the President of the United States under the Argentine-Brazilian treaty of arbitration","type":"primary","url":"https://history.state.gov/historicaldocuments/frus1895p1/d1"}],"topics":[]},"schemaVersion":1}
