Argentine Civil Wars in the context of "Argentine War of Independence"

Argentina, officially the Argentine Republic, is a country in the southern half of South America. It covers an area of 2,780,085 km (1,073,397 sq mi), making it the second-largest country in South America after Brazil, the fourth-largest country in the Americas, and the eighth-largest country in the world. Argentina shares the bulk of the Southern Cone with Chile to the west, and is also bordered by Bolivia and Paraguay to the north, Brazil to the northeast, Uruguay and the South Atlantic Ocean to the east, and the Drake Passage to the south. Argentina is a federal state subdivided into twenty-three provinces, and one autonomous city, which is the federal capital and largest city of the nation, Buenos Aires. The provinces and the capital have their own constitutions, but exist under a federal system. Argentina claims sovereignty over the Falkland Islands, South Georgia and the South Sandwich Islands, the Southern Patagonian Ice Field, and a part of Antarctica.

The earliest recorded human presence in modern-day Argentina dates back to the Paleolithic period. The Inca Empire expanded to the northwest of the country in pre-Columbian times. The modern country has its roots in Spanish colonisation of the region during the 16th century. Argentina rose as the successor state of the Viceroyalty of the Río de la Plata, a Spanish overseas viceroyalty founded in 1776. The Argentine Declaration of Independence on July 9 of 1816 and the Argentine War of Independence (1810–1825) were followed by an extended civil war that lasted until 1880, culminating in the country's reorganisation as a federation. The country thereafter enjoyed relative peace and stability, with several subsequent waves of European immigration, mainly of Italians and Spaniards, influencing its culture and demography.

Juan Manuel José Domingo Ortiz de Rozas y López de Osornio (30 March 1793 – 14 March 1877), nicknamed "Restorer of the Laws", was an Argentine politician and army officer who ruled Buenos Aires Province and briefly the Argentine Confederation. Born into a wealthy family, Rosas independently amassed a personal fortune, acquiring large tracts of land in the process. Rosas enlisted his workers in a private militia, as was common for rural proprietors, and took part in the disputes that led to numerous civil wars in his country. Victorious in warfare, personally influential, and with vast landholdings and a loyal private army, Rosas became a caudillo, as provincial warlords in the region were known. He eventually reached the rank of brigadier general, the highest in the Argentine Army, and became the undisputed leader of the Federalist Party.

In December 1829, Rosas became governor of the province of Buenos Aires and established a dictatorship backed by state terrorism. In 1831, he signed the Federal Pact, recognising provincial autonomy and creating the Argentine Confederation. When his term of office ended in 1832, Rosas departed to the frontier to wage war on the indigenous peoples. After his supporters launched a coup in Buenos Aires, Rosas was asked to return and once again took office as governor. Rosas reestablished his dictatorship and formed the repressive Mazorca, an armed parapolice that killed thousands of citizens. Elections became a farce, and the legislature and judiciary became docile instruments of his will. Rosas created a cult of personality and his regime became totalitarian in nature, with all aspects of society rigidly controlled.

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.
