Brazil, officially the Federative Republic of Brazil (Portuguese:República Federativa do Brasil), is the largest country in both South America and Latin America. As the world's fifth-largest country by both area and population, it is the largest country to havePortuguese as an official language–and the only one in the Americas. Bounded by the Atlantic Ocean on the east, Brazil has a coastline of 7,491 km. It borders all other South American countries except Ecuador and Chile and covers 47.3% of the continent's land area. Its Amazon River basin includes a vast tropical forest, home to diverse wildlife, a variety of ecological systems, and extensive natural resources spanning numerousprotected habitats. This unique environmental heritage makes Brazil one of 17 megadiverse countries, and is the subject of significant global interest and debate regarding deforestation and environmental protection.
Brazil was inhabited by numerous tribal nations prior to the landing in 1500 of explorer Pedro Álvares Cabral. Brazil remained a Portuguese colony until 1808, when the capital of the empire was transferred from Lisbon to Rio de Janeiro. Independence was achieved in 1822 with the creation of the Empire of Brazil, a unitary state governed under a constitutional monarchy and a parliamentary system. The ratification of the first constitution in 1824 led to the formation of a bicameral legislature, now called the National Congress. The country became a presidential republic in 1889 following a military coup d'état. An authoritarian military junta came to power in 1964 and ruled until 1985, after which civilian governance resumed. Brazil's current constitution, formulated in 1988, defines it as a democratic federal republic. The federation is composed of the union of the Federal District, the 26 states, and the 5,570 municipalities.
Brazil's economy is the world's ninth-largest by nominal GDP and seventh-largest by GDP (PPP) as of 2015. A member of the BRICS group, Brazil until 2010 had one of the world's fastest growing major economies, with its economic reforms giving the country new international recognition and influence. Brazil is a founding member of the United Nations, the G20, BRICS, Mercosul, Organization of American States, Organization of Ibero-American States,CPLP, and the Latin Union. Brazil is a regional power in Latin America and a middle power in international affairs, with some analysts identifying it as an emerging global power. One of the world's major bread baskets, Brazil has been the largest producer of coffee for the last 150 years.
