The Foundation of the Argentine State


The process of the foundation of the Argentine State, has fundamental episodes as the Revolution May 25, 1810, in which it was deposed the Viceroy and a governing board was appointed; the Independence of the United Provinces of South America proclaimed on July 9, 1816 at the Congress of Tucumán; the constitution of 1825 that uses the name of United Provinces of the Río de la Plata; and finally the constitution of 1826 which defines the foundation of the Argentine State converting the United Provinces, in República Argentina.

Revolution on May 25, 1810

Los Soldados que lucharon en la Guerra de la Independencia y la Formación del Estado Argentino

After the Napoleonic invasion of Spain and the consequent imprisonment of their king, a revolutionary wave broke out in the colony still ruled by the Virreinato del Río de la Plata. Perhaps under the influence of the recent independence processes in other countries, finally the criollos (natives) became their own policy-makers on May, 25, 1810.

Independence of Argentina

On July 9, 1816, the Congress of Tucumán proclaimed the independence of the Provincias Unidas de América del Sur (United Provinces of the South). But difficulties were far from having ended: they had only just begun.
The first constitution, enacted in 1819, created the legal framework for a unitary country, that is, the powers would center in the capital city. As it could be expected, the provinces opposed this situation and proposed a federal regime which would give them some scope for autonomy. There was a bloody fight between Unitarians and Federals, which dominated the political scene during the first long years of the young country.

Foundation of the Argentine State, creation of Argentina

In 1825, the fundamental law changed the name of Provincias Unidas de América del Sur by Provincias Unidas del Río de la Plata. Finally, the 1826 Constitution made the United Provinces into the Argentine Nation. At this very moment there was a dismemberment of the territories which had made up the Virreinato del Río de la Plata; this process had become evident with the insurrection of the Banda Oriental (today Uruguay) and its subsequent surrender to Brazil. Federalism partly achieved its goals with the 1853 Constitution, which, while establishing this kind of regime, could not put an end to the confrontations between Buenos Aires and the provinces. The power of Buenos Aires as a city-port and a “master key” to the livestock exports (the basis of the Argentine economy) would condition the history of the country.
