The Argentine Confederation 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 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.

The Uruguayan Civil War, also known in Spanish as the Guerra Grande, was a series of armed conflicts between the leaders of Uruguayan independence. While officially the war lasted from 1839 until 1851, it was a part of armed conflicts that started in 1832 and continued until the final military defeat of the Blancos faction in 1904. Out of supporters of presidents Rivera and Oribe grew the Colorado Party and the National Party, both of which received backing and support from foreign sources, including neighboring Empire of Brazil, the Argentine Confederation, Buenos Aires Province as well as European powers, primarily the British Empire and the Kingdom of France, but also a legion of Italian volunteers including Giuseppe Garibaldi. The great diversity of nationalities among the military forces supporting the Colorado Party posed a difficulty when coming to express their struggle in terms of a "national liberation"; instead the Colorado Party side put forward a rhetoric on them defending "humanity" and "civilization" against "tyranny".

The Argentine Civil Wars were a series of civil conflicts of varying intensity that took place through the territories of Argentina from 1814 to 1853. Initiation concurrently with the Argentine War of Independence (1810–1820), 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. The period saw heavy intervention from the Brazilian Empire that fought against state and provinces in multiple wars. Breakaway nations, former territories of the viceroyalty such as the Banda Oriental, Paraguay and the Alto Peru were involved to varying degrees. Foreign powers such as British and French empires put heavy pressure on the fledging nations at times of international war.
The French blockade of the Río de la Plata was a two-year-long naval blockade imposed by France on the Argentine Confederation ruled by Juan Manuel de Rosas. It closed Buenos Aires to naval commerce. It was imposed in 1838 to support the Peru–Bolivian Confederation in the War of the Confederation, but continued after the end of the war. France did not land ground forces, but instead took advantage of the Uruguayan Civil War and the Argentine Civil Wars, supporting Fructuoso Rivera and Juan Lavalle against Manuel Oribe and Rosas.

The rise of the Argentine Republic was a process that took place in the first half of the 19th century in Argentina. The Republic has its origins on the territory of the Viceroyalty of the Río de la Plata, a colony of the Spanish Empire. The King of Spain appointed a viceroy to oversee the governance of the colony. The 1810 May Revolution staged a coup d'état and deposed the viceroy and, along with the Argentine war of independence, started a process of rupture with the Spanish monarchy with the creation of an independent republican state. All proposals to organize a local monarchy failed, and no local monarch was ever crowned.

The rebellion was ultimately defeated at the Battle of Chascomús, and Rosas remained in power in Buenos Aires.
Blood tables: it is a holy action to kill Rosas is an 1843 Argentine libelle written by José Rivera Indarte against the governor of Buenos Aires, Juan Manuel de Rosas. It details 465 purported crimes committed by Rosas or the Popular Restoring Society; later editions increased the number by 22,560. The book was used as a primary source by the early historiography of Juan Manuel de Rosas; modern historians consider its figures to be inflated.
The Battle of Quebracho Herrado, fought on 28 November 1840 in the east of Córdoba Province, Argentina, was a victory for the Argentine federal army, led by former Uruguayan president, Brigadier Manuel Oribe over the Unitarian army led by Brigadier Juan Lavalle, during the Argentine Civil Wars.
The Decembrist revolution was a military coup in the Buenos Aires Province, Argentina. Juan Lavalle, returning with the troops that fought in the Argentine-Brazilian War, performed a coup on December 1, 1828, capturing and killing the governor Manuel Dorrego and ultimately closing the legislature. The rancher Juan Manuel de Rosas organized militias that fought against Lavalle and removed him from power, restoring the legislature. However, as the coup had reignited the Argentine Civil Wars, Rosas was appointed governor of the Buenos Aires province to wage the war against the Unitarian League. José María Paz made from Córdoba a league of provinces, and so did Rosas. The conflict ended a short time after the unexpected capture of Paz, who mistook enemy troops for his own.
