The Rio Acre , in Peru and Bolivia Río Acre , is a right tributary of the Rio Purus in the states of Peru , Bolivia and Brazil .
course
The Rio Acre rises in the eastern foothills of the Peruvian Cordillera , in the La Montana . About a third of its length, the Rio Acre is the border river between Peru and Brazil , later between Bolivia and Brazil. Then it turns north into Brazilian territory and flows into the Rio Purus at Boca do Acre . It is generally navigable from the mouth to the Rio Chapury (480 km), and even further up in the rainy season from January to May.
Economic and political aspects
The river became an important traffic artery at the end of the 19th century because of the newly discovered rubber forests . In 1899 the city of Puerto Acre was founded (later renamed Puerto Alonso ) and in 1904 Cruzeiro do Sul was rebuilt.
In the 19th century there were border disputes between Bolivia, which according to old treaties had actually belonged since 1867, and Brazil , from which the settlement took place. When Bolivia wanted to assert its sovereign rights (appointment of authorities and collection of taxes), the inhabitants of the valley met with fierce resistance. At the end of 1899 the area of the Rio Acre even declared itself an independent Republic of Acre . Only after several military expeditions did Bolivia succeed in asserting its claims. In July 1901, Bolivia signed a lease agreement with a US syndicate, which led to another revolt among the population, secretly supported by Brazil.
On November 18, 1903, Bolivia and Brazil signed the Treaty of Petrópolis , in which most of the disputed area was awarded to Brazil, which had to pay 2 million pounds sterling and to make small area compensations of 3200 km².
