Federal League

The Federal League, also known as the League of the Free Peoples, was a short-lived confederation of South American provinces that existed from 1815 to 1820. Founded and led by José Gervasio Artigas, it aimed to establish a confederal organization for the state emerging from the May Revolution, proclaiming independence from the Spanish Crown in 1815. The league comprised provinces such as Córdoba, Corrientes, Entre Ríos, the Eastern Province, and Santa Fe, and at its largest extent, covered parts of present-day Uruguay, southern Brazil, and Argentine provinces. It confronted centralist governments and was dissolved after its constituent provinces rejoined the United Provinces and Artigas was defeated.
