Saldanha Oliviera e Daun, Joao Carlos, Duke of, a Portuguese statesman; born Nov. 17, 1791; was educated at Lisbon and entered the army. When the French invaded Portugal he took the patriotic side. From 1817 to 1822 he was in South America and took a leading part in the struggle between Brazil and Montevideo. When Brazil declared herself independent of Portugal, Saldanha returned to Lisbon, and in 1825 was appointed governor of Oporto. He took the part of Dom Pedro against Dom Miguel, finally forcing Miguel to sign the convention of Evora Monte (May 26, 1834) and leave Portugal. During 1836-1846 Saldanha lived partly in exile, partly in retirement. Saldanha returned home in 1846; and from that time down to 1856 was alternately at the head of the government. During the reign of Pedro II, he held no great office of state, and under King Louis was kept abroad as ambassador at Rome and London. He died in London, Nov. 28, 1876.
