context_page_description: Bolivia, officially the Plurinational State of Bolivia, is a landlocked country located in western-central South America. The constitutional capital is Sucre, while the seat of government and executive capital is La Paz. The largest city and principal industrial center is Santa Cruz de la Sierra, located on the Llanos Orientales, a mostly flat region in the east of the country.
  The sovereign state of Bolivia is a constitutionally unitary state, divided into nine departments. Its geography varies from the peaks of the Andes in the West, to the Eastern Lowlands, situated within the Amazon Basin. It is bordered to the north and east by Brazil, to the southeast by Paraguay, to the south by Argentina, to the southwest by Chile, and to the northwest by Peru. One-third of the country is within the Andean mountain range. With 1,098,581 km² of area, Bolivia is the fifth largest country in South America, after Brazil, Argentina, Peru, and Colombia, the 27th largest in the world, the largest landlocked country in the Southern Hemisphere and the world's seventh largest landlocked country, after Kazakhstan, Mongolia, Chad, Niger, Mali and Ethiopia.
context_section_description: During the early 20th century, tin replaced silver as the country's most important source of wealth. A succession of governments controlled by the economic and social elite followed laissez-faire capitalist policies through the first 30 years of the 20th century.
  Living conditions of the native people, who constitute most of the population, remained deplorable. With work opportunities limited to primitive conditions in the mines and in large estates having nearly feudal status, they had no access to education, economic opportunity, and political participation. Bolivia's defeat by Paraguay in the Chaco War (1932–35), where Bolivia lost a great part of the Gran Chaco region in dispute, marked a turning-point.
  The Revolutionary Nationalist Movement (MNR), the most historic political party, emerged as a broad-based party. Denied its victory in the 1951 presidential elections, the MNR led a successful revolution in 1952. Under President Víctor Paz Estenssoro, the MNR, having strong popular pressure, introduced universal suffrage into his political platform and carried out a sweeping land-reform promoting rural education and nationalization of the country's largest tin mines.
