Independence and War

In 1827 at ItuzaingO Brazil was defeated. Great Britain, opposing Brazilian expansion south to the RIo de la Plata, helped ultimately to create an independent Uruguay as a buffer state between Argentina and Brazil. The peace (1828) stipulated that the new Uruguayan constitution should be acceptable to both the larger nations. When it was adopted in 1830, Fructuoso Rivera was chosen as president. He was promptly faced with revolts led by his old rival, Lavalleja, and when he was succeeded in office by Manuel Oribe, he himself revolted against Oribe, who was in sympathy with Juan Manuel de Rosas of Argentina. In the long fratricidal struggle that ensued, the two dominant political parties of Uruguay emerged, Rivera's Colorados [reds] and Oribe's Blancos [whites].

Oribe was driven out in 1838, but later with the aid of Rosas returned to begin the long siege of Montevideo. The Italian patriot Garibaldi fought in the Uruguayan wars from 1842 to 1846. In 1851 the Argentine general Urquiza drove out Rosas and brought an end to the Uruguayan civil war. When in 1864 Brazil presented a claim for damages to property and nationals during the civil wars, Uruguay refused to accept it. Brazil invaded and, aided by the Uruguayan general Vanancio Flores (a Colorado), overthrew the Blanco president. Paraguay, under Francisco Solano LOpez, came to the assistance of the Blancos, whereupon Argentina, Brazil, and Uruguay formed a tripartite alliance against Paraguay (see Triple Alliance, War of the). During the 19th and 20th cent. waves of immigration, chiefly from Europe, augmented the Uruguayan population.
