What today is commonly referred as the Independence of Argentina was declared on July 9, 1816, by the Congress of Tucumán. In reality, the congressmen who were assembled in Tucumán declared the independence of the United Provinces of South America, which is one of the official names of the Argentine Republic. The Federal League Provinces, at war with the United Provinces, were not allowed into the Congress. At the same time, several provinces from the Upper Peru that would later become part of present-day Bolivia, were represented at the Congress.
