History
For thousands of years Aysén was home to two very different peoples: the Tehuelche, or Aónikenk, hunters of guanaco on the eastern steppe, and the Chono, canoe nomads of the western channels and islands. European navigators charted the coast from the 16th century, and Jesuit missionaries from Chiloé travelled its channels, but no Spanish or Chilean town was founded here. The Chono disappeared as a distinct people during the colonial era.
Chile and Argentina settled much of the border through British arbitration in 1902, and the state then leased huge tracts to ranching companies, the largest being the Sociedad Industrial de Aysén. Settlers, many of them from Chiloé or Chileans returning from Argentina, cleared land by burning, and vast forest fires in the early 20th century left the silver dead trunks still seen on hillsides. Coyhaique grew from the 1920s as the service town of the steppe, and Puerto Aysén became the port, served today by nearby Puerto Chacabuco.
Until the late 20th century much of the region could be reached only by sea or through Argentina. Construction of the Carretera Austral began in 1976 under the military government and reached Villa O'Higgins in 2000. Since then Aysén has become a centre of Chilean environmental politics: a large hydroelectric project on the Baker and Pascua rivers was rejected in 2014 after years of protests, and the donation of private conservation lands helped create Patagonia National Park in 2018.
