Acre is a state in the extreme south-west of the Northern Region of Brazil, which is bordered by Amazonas, Rondônia, Bolivia and the Ucayali Region (Peru). The capital of this state is the city of Rio Branco, which is nestled in the Valley of Acre and is the most populous city of the entire state.
It has been the capital of the territory since 1920 and the state capital since 1962. Brazilians were originally attracted to the state of Acre for its rich mining activity.
