In 1813 he instructed the delegates from the Banda Oriental to the Buenos Aires constituent assembly to work for a federation of autonomous La Plata provinces, but they were denied admission to the assembly by the centralist military junta. Artigas then championed Uruguayan independence. After an initial setback in 1813 by Buenos Aires and subsequently the restoration of Spanish power (1816), he still managed to rule much of the territory as protector against Spain, Brazil, and Buenos Aires. Finally in 1820, when Artigas had once again renounced the United Provinces of La Plata (Argentina), the Portuguese captured the territory and annexed it to Brazil. Artigas spent his remaining years in exile in Paraguay.

Artigas, José Gervasio

(born June 19, 1764, probably Montevideo [Uru.]—died Sept. 23, 1850, Ibiray, near Asunción, Para.) Soldier and revolutionary leader regarded as the father of Uruguayan independence. In his youth Artigas was a gaucho in what is now Uruguay. Allied with the Buenos Aires junta, he fought for independence from Spain and won a brilliant victory at Las Piedras. His insistence on federalism against the efforts of Buenos Aires to assert control over the entire region led to civil war. He ruled over a portion of what is now Uruguay and central Argentina until a Portuguese invasion forced him into exile in 1820. Uruguay achieved independence in 1828.
