Argentine Constitution of 1853 in the context of "Constitution of Argentina"

The Argentine Civil Wars (Spanish: Guerras civiles argentinas) were a series of civil conflicts of varying intensity that took place in the territories of Argentina from 1814 to 1853. Beginning concurrently with the Argentine War of Independence (1810–1818), the conflict prevented the formation of a stable governing body until the signing of the Argentine Constitution of 1853, followed by low-frequency skirmishes that ended with the Federalization of Buenos Aires in 1880.

The period saw heavy intervention from the Brazilian Empire, which fought against the state and provinces in multiple wars. Breakaway nations, former territories of the Viceroyalty, such as the Banda Oriental, Paraguay and Upper Peru, were involved to varying degrees. Foreign powers such as the British and French empires put heavy pressure on the fledgling nations during international war.

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.
