La gran mentira sobre los "mapuches"

This book reveals the great lie produced by certain argentine and chilean politics talking about "the mapuches" in argentine territory when these people are "the araucanos" who invaded argentina from chile in 1830 and 1860 and killed (genocide) the authentic indians tehuelches who were the original people inhabiting the argentine Patagonia since the times when spanish explorers conquered south america around year 1500 . Mapuches are called the chilean indians but they can not use this word in argentina.
