On this day August 25, 1825
The Uruguayans’ road to independence was much longer than those of other countries in the Americas. Early efforts at attaining independence focused on overthrow of Spanish rule, a process begun by Jose Gervasio Artigas in 1811 when he led his forces to victory against the Spanish in the battle of Las Piedras on May 18, 1811.
In 1816, Portuguese troops invaded present-day Uruguay, which led to its eventual annexation by Brazil in 1821 under the provincial name, Provincia Cisplatina. On April 19, 1825, thirty-three Uruguayan exiles led by Juan Antonio Lavalleja returned from Buenos Aires to lead an insurrection in Uruguay. They were known as the Treinta y Tres Orientales.
Their actions inspired representatives from Uruguay to meet in Florida, a town in the recently liberated area, where they declared independence from Brazil on August 25, 1825. Uruguayan independence was not recognized by its neighbors until 1828, after the Argentina-Brazil War, when Britain, in search of new commercial markets, brokered peace between Argentina, Brazil, and Uruguay.
On August 27, 1828, Uruguay was formally proclaimed independent at the preliminary peace talks between Brazil and Argentina.
