The Acre War, known in Brazil as Acrean Revolution (Portuguese: Revolução Acreana) and in Spanish as Guerra del Acre ("War of the Acre") was a border conflict between Bolivia and Brazil over the Acre Region, which was rich in rubber and gold deposits. The conflict had two phases between 1899 and 1903, and ended with an Acrean victory and the subsequent Treaty of Petrópolis, which ceded Acre to Brazil. The outcome also affected territories disputed with Peru.
