Brazil

Brazil, officially the Federative Republic of Brazil, is the largest country in South America. It is also the world's fifth-largest country by area and the seventh-largest by population, with over 213 million people. Brazil is a federation composed of 26 states and a Federal District, which hosts the capital, Brasília. Its most populous city is São Paulo, followed by Rio de Janeiro. Brazil has the largest Lusophone population in the world and is the only Portuguese-speaking country in the Americas, where it is the official language. Bounded by the Atlantic Ocean on the east, Brazil has a coastline of 7,491 kilometers (4,655 mi), among the longest in the world. Covering roughly half of South America's land area, it borders all other countries and territories on the continent except Ecuador and Chile. Brazil encompasses a wide range of tropical and subtropical landscapes, as well as wetlands, savannas, plateaus, and low mountains. It contains most of the Amazon basin, including the world's largest river system and most extensive virgin tropical forest. Brazil has diverse wildlife, a variety of ecological systems, and extensive natural resources spanning numerous protected habitats. It ranks first among 17 megadiverse countries, with its natural heritage being the subject of significant global interest, as environmental degradation (through processes such as deforestation) directly affect global issues such as climate change and biodiversity loss. Brazil was inhabited by various indigenous peoples prior to the landing of Portuguese explorer Pedro Álvares Cabral in 1500. The territory was subsequently claimed and settled by Portugal, which founded the country's first city, São Vicente, in 1532 and imported enslaved Africans to work on plantations. Brazil remained a colony until 1815, when it was elevated to a united kingdom with Portugal after the transfer of the Portuguese court to Rio de Janeiro. Prince Pedro of Braganza declared Brazilian independence in 1822 and, after waging a war against Portugal, established the Empire of Brazil. The country's first constitution in 1824 established a bicameral legislature and enshrined principles such as freedom of religion and the press; slavery was gradually abolished until its final abolition in 1888. Brazil became a presidential republic following a military coup d'état in 1889. An armed revolution in 1930 ended the First Republic and brought Getúlio Vargas to power. Vargas' self-coup in 1937 ushered the authoritarian Estado Novo, in which he oversaw Brazil's involvement in World War II. Democracy was restored after Vargas' ousting in 1945. An authoritarian military dictatorship emerged in 1964 with support from the United States and ruled until 1985, after which civilian governance resumed. Brazil's current constitution, enacted in 1988, defines it as a democratic federal republic. Brazil is a regional and middle power, and has been described as a rising global power. It is an emerging, upper-middle income economy and newly industrialized country, with one of the 10 largest economies in the world in both nominal and PPP terms, the largest economy in Latin America and the Southern Hemisphere, and the largest share of wealth in South America. With a complex and highly diversified economy, Brazil is one of the world's major or primary exporters of various agricultural goods, mineral resources, and manufactured products. The country ranks thirteenth in the world by number of UNESCO World Heritage Sites. Brazil is a founding member of the United Nations, the G20, BRICS, G4, Mercosur, Organization of American States, Organization of Ibero-American States, and the Community of Portuguese Language Countries; it is also an observer state of the Arab League and a major non-NATO ally of the United States.
