Araucanía or Araucana was the Spanish name given to the region of Chile inhabited by the Mapuche peoples known as the Moluche (also known as Araucanos by the Spanish) in the 18th century. Prior to the Spanish Conquest of Chile, the lands of the Moluche lay between the Itata River and Toltén River. Following the great rising of the Moluche and Huilliche after the Battle of Curalaba in 1598 during the Arauco War, the Spanish were expelled from south of the Bío-Bío River. After many decades of further warfare, the bounds of Araucania were recognized by the Spanish as being between the Bío-Bío River and Toltén River. This old region of Araucanía now is divided between the Bío-Bío Region and the Araucanía Region of Chile.
