The governor of Buenos Aires Province 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.

Brazil–Uruguay relations encompass many complex relations over the span of three centuries, beginning in 1680 with the establishment of the Colónia do Sacramento, to the present day, between the Federative Republic of Brazil and the Oriental Republic of Uruguay. Brazil and Uruguay are neighbouring countries in South America, and share close political, economic and cultural ties. The singularity of the bilateral relationship between the two countries originates from a strong historical connection, as both countries having been territories of the Portuguese Empire and sharing the same language – marked by important events, such as the establishment of the Colónia do Sacramento in 1680, the invasion of the Banda Oriental by Brazil in 1815 and the subsequent creation of the Província Cisplatina, and Uruguay's independence from Brazil in 1828. The bilateral relationship was further defined by the Uruguayan Civil War (1839–1851) and the Paraguayan War (1864–1870).

The war was part of a decades-long dispute between Argentina and Brazil for influence over Uruguay and Paraguay, and hegemony over the Platine region. The conflict took place in Uruguay and northeastern Argentina, and on the Río de la Plata. Uruguay's internal troubles, including the longrunning Uruguayan Civil War, were heavily influential factors leading to the Platine War.
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. 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. 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 Upper Peru were involved to varying degrees. Foreign powers such as the British and French empires put heavy pressure on the fledgling nations at times of international war.
