Originally a municipality of the state of Goiás dating from before the eighteenth century, it had part of its territory integrated into the new Federal District, when the capital was transferred from Rio de Janeiro to Brasília in 1960. To serve as the seat of the remaining municipality belonging to the state of Goiás, a small city was built, which also has the name Planaltina de Goiás, but popularly known as Brasilinha (little Brasília). Planaltina, D.F., is therefore the oldest urban area of the Federal District. In recent years it has grown haphazardly with many new housing areas being built to accommodate landless and homeless migrants who arrive daily looking for work in Brasília.
