There has been a decennial dispute between Chile and the Mapuche State especially since the 19th Century. The history of the Mapuche dates back to BC and is a fairly well-established community that fought in the name of independence. The Mapuches, who resisted the occupation during the years when the Spanish state had large colonies, achieved their independence in 1818. They lost their independence when the Chilean state invaded their territory in the 1880s.
