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.[1] 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 resisted attacks by 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.[2]


Administration of Juan Manuel de Rosas

Modern Argentina is a small subset (approx. 1/3) of the Viceroyalty of the Río de la Plata, a colony of Spain which also included present-day Bolivia, Uruguay, part of Chile and Peru and most of Paraguay. Long after attaining independence, Argentina attacked and conquered large areas of indigenous land.

Viceroyalty of the Río de la Plata


Treaty of Montevideo that made Uruguay a new state.[3]

When Argentine forces returned to Buenos Aires, Juan Lavalle led a military coup against governor Manuel Dorrego. He executed him and began a campaign against all federals, supported by José María Paz in Córdoba, who deposed Juan Bautista Bustos and took similar measures against federals. The rancher Juan Manuel de Rosas organized the resistance against Lavalle, forcing him out of government and restoring the Legislature. Paz organized the Unitarian League with the provinces that joined him, and Rosas signed the Federal Pact with Entre Ríos and Santa Fe. All the unitarian provinces were defeated and joined the Pact, and became the Argentine Confederation. Rosas declined a new term as governor after the victory over the unitarian league.[4]

Rosas left Buenos Aires and waged the first campaign in the desert in the south, to prevent further malones from the indigenous peoples. The campaign combined military actions and negotiations and succeeded in preventing malones for several years. Despite being absent, the political influence of Rosas in Buenos Aires was still strong, and his wife Encarnación Ezcurra was in charge of keeping good relations with the people of the city. On October 11, 1833, the city was filled with announcements of a trial against "The restorer of laws" (a newspaper, but it was misunderstood as a trial against Rosas himself, who held that title). A large number of gauchos and poor people instigated the Revolution of the Restorers, a demonstration at the gates of the legislature, praising Rosas and demanding the resignation of Governor Juan Ramón Balcarce. The troops who were organized to fight the demonstration instead mutinied and joined it. The legislature finally gave up the trial, and a month later ousted Balcarce and replaced him with Juan José Viamonte. Still, the social unrest led many people to believe that only Rosas could secure order and that Viamonte or Manuel Vicente Maza would be unable to do so. The murder of Facundo Quiroga in Córdoba increased this belief, so the legislature appointed him governor in 1835, with the sum of public power.[5]

Rosas faced a difficult military threat during first years of his second administration. First, the

Berón de Astrada, from Corrientes, opposed Rosas as well, and Juan Lavalle organized an army to take Buenos Aires. The ranchers mutinied in Chascomús and organized the "Freemen of the South" militia.[6]

Battle of Vuelta de Obligado, part of the Anglo-French blockade of the Río de la Plata

Rosas overcame all these threats. The Peru–Bolivian Confederation was defeated by Chile and ceased to exist. Cullen was defeated and shot, and Astrada was defeated by Justo José de Urquiza. The ranchers were defeated as well. The diplomat Manuel Moreno channeled the protests of the British merchants in Buenos Aires who were impacted by the blockade; this added to French doubts about maintaining a conflict that they had expected to be quite short. France finally lifted the blockade with the Mackau-Arana treaty. Lavalle lost French support but sought to continue the conflict anyway. He retreated before reaching Buenos Aires, without starting any battles, and escaped to the North. He was chased by Oribe, now in charge of Argentine armies, and died in unclear circumstances.[7]

Despite the French defeat, Uruguay was still an open war theater. Manuel Oribe claimed to be the

Paraná river by navigating to Paraguay and returning. The Argentine army resisted the invasion of the river at several points along the Paraná (most notably during the battle of Vuelta de Obligado), but could not stop them. The damage to the British and French ships, however, were so great that both countries eventually resigned and lifted the blockade.[8]

Justo José de Urquiza, governor of Entre Ríos, had supported Rosas so far, but the ranchers of his province had an expanding economy and wanted to have a local customs, able to engage in commerce with other countries directly. The port of Buenos Aires had that exclusive right. Entre Ríos also requested the federalization of the national income generated by exports, and the calling of a constituent assembly to write a constitution, as laid out in the Federal Pact. Urquiza made a pronunciamiento, resuming the rights of Entre Ríos to commerce and negotiations with other countries, instead of delegating such powers to Buenos Aires. Rosas declared war against him, but Urquiza defeated Rosas at the battle of Caseros, forcing him into exile.[9]

Secession and return of Buenos Aires

The San Nicolás Agreement led to the sanction of the Argentine Constitution of 1853.

Urquiza was not a unitarian, but another federalist like Rosas. Thus, the unitarians did not support him, but opposed him as they did Rosas. Urquiza's ambition to reduce the national centralism of Buenos Aires and promote a higher federalization of the country generated conflicts with the unitarians. Urquiza called the San Nicolás Agreement, so that all provinces agreed to convene the 1853 Constituent Assembly. This was resisted in Buenos Aires, and the unitarians took advantage of a temporary absence of Urquiza from the city to stage the Revolution of 11 September and secede Buenos Aires from the confederation. It was now the State of Buenos Aires, and the other Argentine provinces were now the Argentine Confederation.[10]

Manuel Guillermo Pinto was appointed governor of Buenos Aires, and removed the delegates from the constituent assembly. The capital of the Confederation was now located in Paraná, Entre Ríos. Buenos Aires attempted military actions against the Confederation, to prevent the work of the Assembly, but failed. The Argentine Constitution of 1853 was sanctioned on May 1, 1853, inviting Buenos Aires to return. Buenos Aires wrote its own constitution in 1854. Both countries, the Confederation and the State of Buenos Aires, accepted the status quo, with a serious danger of the secession becoming permanent.[11]

The Confederation attacked Buenos Aires in 1856, led by Jerónimo Costa, who was defeated by Bartolomé Mitre. Mitre got 140 prisoners: he executed 125 of them.[12]

in 1857, Mitre and other politicians in Buenos Aires considered making the secession a definitive one, renaming the state to the "Republic of the Río de la Plata". The project was resisted by Domingo Faustino Sarmiento, who began his conflicts with Mitre. The project did not find popular support, and was forgotten.[13]

The Confederation had a political commotion with the murder of Nazario Benavídez, from San Juan, carried out by supporters of Sarmiento. Urquiza defeated Mitre at the Battle of Cepeda, and laid siege to the city. Most federals thought that Urquiza should occupy Buenos Aires and impose the Constitution on the rebellious province. However, Urquiza just stayed outside, and sought the mediation of the Paraguayan Francisco Solano López. Buenos Aires would call a Constituent Assembly, to accept the National Constitution or requesting amendments, and rejoin the Confederation.[14]

The Assembly requested several amendments, the most important of which was that Buenos Aires would not be the capital city of Argentina. This would allow the city to keep the exclusive use of the port. With Santiago Derqui as the new president of the Confederation, the amendments were accepted, and the new National constitution promulgated. However, the murder of governor José Antonio Virasoro generated new military conflicts between Buenos Aires and the Confederation. Mitre defeated Urquiza at the battle of Pavón in 1861, and Buenos Aires returned to the Confederation, which would then become the modern Republic of Argentina.[15]
