Well the Chilean government took it away from them because the Spanish conquistadors couldn't do it for 300 years.
The Spanish that came to Chile fought hard against the Mapuche but they held, even they gave the Spanish some nasty defeats. The Spanish could never beat the Mapuches that's why, during the Spanish rule, the Kingdom of Chile ended in the Bío-Bío river because crossing that you would be entering Mapuche territory.
At the end of the XIX century, the Mapuche were very weakened for several reasons so the Chilean government managed to get in the territory and claim it as theirs although even to this day, some communities still protest and fight against the police to get their lands back.
The Mapuche people speak:SpanishMapudungun (sometimes called the Mapuche Language)
Chile has no meaning in Spanish. It is probably the Mapuche word "chilli", meaning where the land ends.
Well first of all they are not indians since they don't come from that country, they are aboriginals. Answering your question is hard, since there are many opinions to this questions, some people think that the Mapuche are just a problem for the government because they protest to get their land back and they also fight for it against the police and agriculturist who live in what is their ancestral land. Other people (and this is my case) think that the Mapuche are a part of Chilean culture and history so they deserve to have their lands back because they never gave their land, it was stolen. There is many racism against the Mapuche from some people but others like me, actually support them.
The tribes that fought the Incas included the Mapuche and the Shuar. The Spanish were the Inca Empire's final enemies. They took their land and stole their goods.
