Federal District (Brazil)
The Federal District (Portuguese: Distrito Federal; Portuguese pronunciation: [dʒiʃˈtɾitu fedeˈɾaw]) is one of 27 federative units of Brazil. Located in the Central Plateau of the Brazilian Highlands, the Federal District is divided into 31 administrative regions, and contains the Brazilian capital city, Brasília, which is also the seat of government of the Federal District. The capital — the seat of the three branches of the federal government of Brazil (legislative, executive and the judiciary) — is the main attraction of this dry area, whose climate has only two seasons. During the dry season (winter), the humidity can reach critical levels, mainly in the peak hours of the hottest days. The artificial Paranoá Lake, with almost 40 km2 (15 sq mi) and 500 million cubic metres (410,000 acre·ft) of water, was built to minimize the severe dry, climatic conditions of winter in the Cerrado vegetation.
History
The capital of Brazil was transferred from Rio de Janeiro to Brasília on April 21, 1960, which its new territory was then split off from Goiás. After the transfer, the old Federal District (1891-1960) became the Guanabara State (Estado da Guanabara), which existed from 1960 until 1975 when Guanabara State and Rio de Janeiro State (Estado do Rio de Janeiro) merged and assumed the name Rio de Janeiro State, having as capital the city of Rio de Janeiro.
