Buenos Aires is the capital and largest city of Argentina, and the second-largest metropolitan area in South America, after Greater So Paulo. It is located on the western shore of the estuary of the Ro de la Plata, on the southeastern coast of the South American continent. Greater Buenos Aires conurbation, which also includes several Buenos Aires Province districts, constitutes the third-largest conurbation in Latin America, with a population of around thirteen million. The city of Buenos Aires is not a part of Buenos Aires Province, nor is it the Province's capital, but an autonomous district. In 1880, after decades of political infighting, Buenos Aires was federalised and removed from Buenos Aires Province. The city limits were enlarged to include the towns of Belgrano and Flores (both are currently neighborhoods of the city).
