Angol is a commune and capital city of the Malleco Province in the Araucanía Region of southern Chile. It is located at the foot of the Nahuelbuta Range and next to the Vergara River, that permitted communications by small boats to the Bío-Bío River and Concepción. This strategic position explains the successive foundations of this city during the Arauco War. It was first founded in 1553 as a "conquistador" fort of Confines, the fort was later destroyed and rebuilt several times and it was not until the Pacification of Araucania in late 19th century that it was rebuilt with the name of Angol. The city has a current population of approximately 49,000. Within the electoral divisions of Chile, it belongs to the 48th electoral district and the 14th senatorial circumscription.
