Bolivia in the context of "Brazil"

Peru, officially the Republic of Peru, is a country in western South America. It is bordered to the north by Ecuador and Colombia, to the east by Brazil, to the southeast by Bolivia, to the south by Chile, and to the south and west by the Pacific Ocean. Peru is a megadiverse country, with habitats ranging from the arid plains of the Pacific coastal region in the west, to the peaks of the Andes mountains extending from the north to the southeast of the country, to the tropical Amazon basin rainforest in the east with the Amazon River. Peru has a population of over 32 million, and its capital and largest city is Lima. At 1,285,216 km (496,225 sq mi), Peru is the 19th largest country in the world, and the third largest in South America.

Peruvian territory was home to several cultures during the ancient and medieval periods, and has one of the longest histories of civilization of any country, tracing its heritage back to the 10th millennium BCE Caral–Supe civilization, the earliest civilization in the Americas and considered one of the cradles of civilization. Notable succeeding cultures and civilizations include the Nazca culture, the Moche, Wari and Tiwanaku empires, the Kingdom of Cusco, and the Inca Empire, the largest known state in the pre-Columbian Americas. The Spanish Empire conquered the region in the 16th century and Charles V established a viceroyalty with the official name of the Kingdom of Peru that encompassed most of its South American territories, with its capital in Lima. Higher education started in the Americas with the official establishment of the National University of San Marcos in Lima in 1551.

An Indigenous language, or autochthonous language, is a language that is native to a region and spoken by its Indigenous peoples. Indigenous languages are not necessarily national languages but they can be; for example, Aymara is both an Indigenous language and an official language of Bolivia. Also, national languages are not necessarily Indigenous to the country.

Many Indigenous peoples worldwide have stopped the generational passage of their ancestral languages and have instead adopted the majority language as part of their acculturation into their host culture. Furthermore, many Indigenous languages have been subject to linguicide (language killing). Recognizing their vulnerability, the United Nations proclaimed 2019 the International Year of Indigenous Languages "to draw attention to the critical loss of Indigenous languages and the urgent need to preserve, revitalize and promote Indigenous languages."

The Indigenous peoples of the Americas are the peoples who are native to the Americas or the Western Hemisphere. Their ancestors are among the pre-Columbian population of South or North America, including Central America and the Caribbean. Indigenous peoples live throughout the Americas. While often minorities in their countries, Indigenous peoples are the majority in Greenland and close to a majority in Bolivia and Guatemala.

There are at least 1,000 different Indigenous languages of the Americas. Some languages, including Quechua, Arawak, Aymara, Guaraní, Nahuatl, and some Mayan languages, have millions of speakers and are recognized as official by governments in Bolivia, Peru, Paraguay, and Greenland.

Chile, officially the Republic of Chile, is a country in western South America. It is the southernmost country in the world and the closest to Antarctica, extending along a narrow strip of land between the Andes Mountains and the Pacific Ocean. According to the 2024 census, Chile had an enumerated population of 18.5 million. The country covers a territorial area of 756,102 square kilometers (291,933 sq mi), sharing borders with Peru to the north, Bolivia to the northeast, Argentina to the east, and the Drake Passage to the south. It also administers several Pacific islands, including Juan Fernández, Isla Salas y Gómez, Desventuradas, and Easter Island, and claims about 1,250,000 square kilometers (480,000 sq mi) of Antarctica as the Chilean Antarctic Territory. The capital and largest city is Santiago, and the national language is Spanish.

Spain conquered and colonized the region in the mid-16th century, replacing Inca rule; however, they failed to conquer the autonomous tribal Mapuche people who inhabited what is now south-central Chile. Chile emerged as a relatively stable authoritarian republic in the 1830s after their 1818 declaration of independence from Spain. During the 19th century, Chile experienced significant economic and territorial growth, putting an end to Mapuche resistance in the 1880s and gaining its current northern territory in the War of the Pacific (1879–83) by defeating Peru and Bolivia.

The Andes (/ˈændiːz/ AN-deez), Andes Mountains or Andean Mountain Range (Spanish: Cordillera de los Andes; Quechua: Anti) are the longest continental mountain range in the world, forming a continuous highland along the western edge of South America. The range is 8,900 km (5,500 mi) long and 200 to 700 km (120 to 430 mi) wide (widest between 18°S and 20°S latitude) and has an average height of about 4,000 m (13,000 ft). The Andes extend from south to north through seven South American countries: Argentina, Chile, Bolivia, Peru, Ecuador, Colombia, and Venezuela.

Along their length, the Andes are split into several ranges, separated by intermediate depressions. The Andes are the location of several high plateaus—some of which host major cities such as Arequipa, Bogotá, Cali, Medellín, El Alto, La Paz, Mérida, Santiago and Sucre. The Altiplano Plateau is the world's second highest after the Tibetan Plateau. These ranges are in turn grouped into three major divisions based on climate: the Tropical Andes, the Dry Andes, and the Wet Andes.

The Amazon basin is the part of South America drained by the Amazon River and its tributaries. The Amazon drainage basin covers an area of about 7,000,000 km (2,700,000 sq mi), or about 35.5 percent of the South American continent. It is located in the countries of Bolivia, Brazil, Colombia, Ecuador, Guyana, Peru, Suriname, and Venezuela, as well as the territory of French Guiana.

Most of the basin is covered by the Amazon rainforest, also known as Amazonia. With a 6 million km (2.3 million sq mi) area of dense tropical forest, it is the largest rainforest in the world.

The Inca Empire, officially known as the Realm of the Four Parts (Quechua: Tawantinsuyu pronounced [taˈwantiŋ ˈsuju], lit. 'land of four parts'), was the largest empire in pre-Columbian America. The administrative, political, and military center of the empire was in the city of Cusco. The Inca civilisation rose from the Peruvian highlands sometime in the early 13th century. The Portuguese explorer Aleixo Garcia was the first European to reach the Inca Empire in 1524. Later, in 1532, the Spanish began the conquest of the Inca Empire, and by 1572 the last Inca state was fully conquered.

From 1438 to 1533, the Incas incorporated a large portion of western South America, centered on the Andean Mountains, using conquest and peaceful assimilation, among other methods. At its largest, the empire joined modern-day Peru with what are now western Ecuador, western and south-central Bolivia, northwest Argentina, the southwesternmost tip of Colombia and a large portion of modern-day Chile, forming a state comparable to the historical empires of Eurasia. Its official language was Quechua.

The Río de la Plata basin (Spanish: Cuenca del Plata, Portuguese: Bacia do Prata), more often called the River Plate basin in scholarly writings, sometimes called the Platine basin or Platine region, is the 3,170,000-square-kilometre (1,220,000 sq mi) hydrographical area in South America that drains to the Río de la Plata. It includes areas of southeastern Bolivia, southern and central Brazil, the entire country of Paraguay, most of Uruguay, and northern Argentina. Making up about one fourth of the continent's surface, it is the second largest drainage basin in South America (after the Amazon basin) and one of the largest in the world.

The main rivers of the La Plata basin are the Paraná River, the Paraguay River (the Paraná's main tributary), and the Uruguay River.

The Southern Common Market (commonly known by abbreviation Mercosur in Spanish and Mercosul in Portuguese) is a South American trade bloc established by the Treaty of Asunción in 1991 and Protocol of Ouro Preto in 1994. Its full members are Argentina, Bolivia, Brazil, Paraguay, and Uruguay. Venezuela is a full member but has been suspended since 1 December 2016. Chile, Colombia, Ecuador, Guyana, Panama, Peru, and Suriname are associate countries.

Mercosur's origins are linked to the discussions for the constitution of a regional economic market for Latin America, which go back to the treaty that established the Latin American Free Trade Association in 1960, which was succeeded by the Latin American Integration Association in the 1980s. At the time, Argentina and Brazil made progress in the matter, signing the Iguaçu Declaration (1985), which established a bilateral commission, which was followed by a series of trade agreements the following year. The Integration, Cooperation and Development Treaty, signed between both countries in 1988, set the goal of establishing a common market, which other Latin American countries could join. Paraguay and Uruguay joined the process and the four countries became signatories to the Treaty of Asunción (1991), which established the Southern Common Market, a trade alliance aimed at boosting the regional economy, moving goods, people among themselves, workforce and capital. Initially a free trade zone was established, in which the signatory countries would not tax or restrict each other's imports. As of 1 January 1995, this area became a customs union, in which all signatories could charge the same quotas on imports from other countries (common external tariff). The following year, Bolivia and Chile acquired membership status. Other Latin American nations have expressed interest in joining the group.
