"Not the native peoples who had inhabited the land for a millenia or two! "
Who also stole it from the earlier inhabitants.
The Aborigines in Aus. MAY be the only population that still resides in it's original area ( thought I believe they migrated there, it was not inhabited beforehand.)
Hmm. the Esquimaux ( driven into fringe areas by later migration) and the Terra del Feugo people might also claimed to be original inhabitants...
But even the Celts invaded a populated land and drove off the original owners.
