This video was interesting. It was made in 2017. It seems like the Mapuche lay claim to the land south of the Bío Bío River (Concepción) to just north of Valdivia. Only, I met a half-Mapuche woman in the local feria (who is against the Mapuche war) who said that the Mapuche also lay claim to Linares. Does that seem right? Or not right? ..
