Its government was a representative parliamentary constitutional monarchy under the rule of Emperors Dom PedroI and his son Dom PedroII. A colony of the Kingdom of Portugal, Brazil became the seat of the Portuguese colonial Empire in 1808, when the Portuguese Prince regent, later King Dom JoaoVI, fled from Napoleon's invasion of Portugal and established himself and his government in the Brazilian city of Rio de Janeiro. JoaoVI later returned to Portugal, leaving his eldest son and heir, Pedro, to rule the Kingdom of Brazil as regent. On 7 September 1822, Pedro declared the independence of Brazil and, after waging a successful war against his father's kingdom, was acclaimed on 12 October as PedroI, the first Emperor of Brazil. The new country was huge but sparsely populated and ethnically diverse., The Paraguay River (Rio Paraguay in Spanish, Rio Paraguai in Portuguese, Ysyry Paraguai in Guarani) is a major river in south-central South America, running through Brazil, Bolivia, Paraguay and Argentina. It flows about from its headwaters in the Brazilian state of Mato Grosso to its confluence with the Parana River north of Corrientes and Resistencia., Bolivia (; ), officially known as the Plurinational State of Bolivia, is a landlocked country located in western-central South America.

Together they make up most of Earth's western hemisphere and comprise the "New World". , South America is a continent located in the western hemisphere, mostly in the southern hemisphere, with a relatively small portion in the northern hemisphere. It is also considered a subcontinent of the Americas, which is the model used in nations that speak Romance languages. The reference to South America instead of other regions (like Latin America or the Southern Cone) has increased in the last decades due to changing geopolitical dynamics (in particular, the rise of Brazil)., Uruguay, officially the Oriental Republic of Uruguay, is a country in the southeastern region of South America. It borders Argentina to its west and Brazil to its north and east, with the Rio de la Plata (River of Silver) to the south and with the Atlantic Ocean to the southeast.

It particularly devastated Paraguay, which suffered catastrophic losses in population - almost 70% of its adult male population died, according to some counts - and was forced to cede territory to Argentina and Brazil.
