Constitution of Argentina in the context of "Argentine War of Independence"

The United Provinces of the Río de la Plata (Spanish: Provincias Unidas del Río de la Plata), earlier known as the United Provinces of South America (Spanish: Provincias Unidas de Sudamérica), was a name adopted in 1816 by the Congress of Tucumán for the region of South America that declared independence in 1816, with the Sovereign Congress taking place in 1813, during the Argentine War of Independence (1810–1818) that began with the May Revolution in May of 1810. It originally comprised rebellious territories of the former Spanish Viceroyalty of the Río de la Plata dependencies and had Buenos Aires as its capital.

The name Provincias del Río de la Plata (formally adopted during the Cortes of Cádiz to designate the Viceroyalty of the Río de la Plata) alludes to the Junta Provisional Gubernativa de las Provincias del Río de la Plata or Primera Junta. It is best known in Argentinean literature as Provincias Unidas del Río de la Plata ('United Provinces of the River Plate' i.e. 'river of silver'), this being the most common name (since 1811) in use for the country until the enactment of the 1826 Constitution. The Argentine National Anthem refers to the state as "the United Provinces of the South". The Constitution of Argentina recognises Provincias Unidas del Río de la Plata as one of the official names of the country, referred to as "Argentine Nation" (Nación Argentina) in modern legislation.

Prior restraint (also referred to as prior censorship or pre-publication censorship) is censorship imposed, usually by a government or institution, on expression, that prohibits particular instances of expression. It is in contrast to censorship that establishes general subject matter restrictions and reviews a particular instance of expression only after the expression has taken place.

In some countries (e.g., United States, Argentina) prior restraint by the government is forbidden, subject to exceptions, by their respective constitutions.

The Argentine Confederation (Spanish: Confederación Argentina) was the last predecessor state of modern Argentina; its name is still one of the official names of the country according to the Argentine Constitution, Article 35. It was the name of the country from 1831 to 1852, when the provinces were organized as a confederation without a head of state. The governor of Buenos Aires Province (Juan Manuel de Rosas during most of the period) managed foreign relations during this time, Under his rule, the Argentine Confederation engaged in conflicts with Brazil, Bolivia, Uruguay, France and the United Kingdom, as well as other Argentine factions during the Argentine Civil Wars.

Rosas was ousted from power in 1852 by Justo José de Urquiza, after the battle of Caseros. Urquiza convened the 1853 Constituent Assembly to write a national constitution. Buenos Aires resisted Urquiza and seceded from the Confederation in 1852, becoming the State of Buenos Aires; the province would return to Argentina in 1861.
