The 1851 Boundary Treaty established between Brazil and Uruguay as a result of the Uruguayan Civil War and conflicts with Brazil and Argentina; the result of the treaty was a step towards the acceptance of Uruguay's independence from neighboring territories. [1]
Uruguay rewarded Brazil's financial and military support by signing five treaties in 1851 that provided for perpetual alliance between the two countries. The Treaty of Montevideo (1828) confirmed Brazil's right to intervene in Uruguay's internal affairs. The treaties also allowed joint navigation on the Uruguay River and its tributaries, and tax exempted cattle and salted meat exports. The treaties also acknowledged Uruguay's debt to Brazil for its aid against the Blancos, and Brazil's commitment for granting an additional loan. In addition, Uruguay renounced its territorial claims to a border in the Ibicuí River and accepted the Quaraí River as northernmost border with Brazil, thereby reducing its area the size of the Cisplatina Province, and recognized Brazil's exclusive right of navigation in the Lagoa Mirim and the Jaguarão River , the natural border between the countries. However, a dispute still exists in the vicinity of Masoller over which creek was meant to mark the border in that area. Uruguay also allowed Brazilians to legally own slaves in their properties despite the fact that after 1842 slavery wasn't legal in the country. [ citation needed ]

The Río de la Plata, also called the River Plate or La Plata River in English, is the estuary formed by the confluence of the Uruguay River and the Paraná River at Punta Gorda. It empties into the Atlantic Ocean and forms a funnel-shaped indentation on the southeastern coastline of South America. Depending on the geographer, the Río de la Plata may be considered a river, an estuary, a gulf, or a marginal sea. If considered a river, it is the widest in the world, with a maximum width of 220 kilometres (140 mi).
The Paraguayan War, also known as the War of the Triple Alliance, was a South American war that lasted from 1864 to 1870. It was fought between Paraguay and the Triple Alliance of Argentina, the Empire of Brazil, and Uruguay. It was the deadliest and bloodiest inter-state war in Latin American history. Paraguay sustained large casualties, but even the approximate numbers are disputed. Paraguay was forced to cede disputed territory to Argentina and Brazil. The war began in late 1864, as a result of a conflict between Paraguay and Brazil caused by the Uruguayan War. Argentina and Uruguay entered the war against Paraguay in 1865, and it then became known as the "War of the Triple Alliance."

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 Colombian–Peruvian territorial dispute was a territorial dispute between Colombia and Peru, which, until 1916, also included Ecuador. The dispute had its origins on each country's interpretation of what Real Cedulas Spain used to precisely define its possessions in the Americas. After independence, all of Spain's former territories signed and agreed to proclaim their limits in the basis of the principle of uti possidetis juris, which regarded the Spanish borders of 1810 as the borders of the new republics. However, conflicting claims and disagreements between the newly formed countries eventually escalated to the point of armed conflicts on several occasions.
