Rio de Janeiro

Rio de Janeiro, also known simply as Rio, is the capital of the state of Rio de Janeiro. It is the second-most-populous city in Brazil after São Paulo and the sixth-most-populous city in the Americas. Founded in 1565, the city was initially the seat of the Captaincy of Rio de Janeiro, a domain of the Portuguese Empire. In 1763, it became the capital of the State of Brazil. In 1808, when the Portuguese Royal Court moved to Brazil, Rio de Janeiro became the seat of the court of Queen Maria I of Portugal. Under the leadership of her son, prince regent John of Braganza, Maria raised Brazil to the dignity of a kingdom within the United Kingdom of Portugal, Brazil, and Algarves. Rio remained as the capital of the pluricontinental monarchy until 1822, when the Brazilian War of Independence began. This is one of the few instances in history that the capital of a colonizing country officially shifted to a city in one of its colonies. Rio de Janeiro subsequently served as the capital of the Empire of Brazil, until 1889, and then the capital of republican Brazil until 1960 when the capital was moved to Brasília. Rio de Janeiro has the second largest municipal GDP in the country, and 30th-largest in the world as of 2008, estimated at R$343 billion.
