Concepción Province, Chile

The region was earlier populated by indigenous Mapuche people, and the city of Concepción was established on 5 October 1550 by Spanish conquistador Pedro de Valdivia as a base for slave labor and a port. However, the region was the site of constant skirmishes between the Mapuche and the Spanish, and was burnt down multiple times. The Spanish fortified the region, and the Biobio River formed a natural boundary between the Mapuche and Spanish occupied regions. It later developed into a major agriculture and pastoral center.^[4][5]

The Biobio Region was established on 10 July 1974, by Law No. 575, which reorganised Chile into thirteen regions.^[6] The region is divided into three provinces–Concepción, Biobío, and Arauco, which are further divided into 33 communes.^[7]
