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 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.
