If geopolitics predating the Roman Republic by 500 years justifies kicking people off land they were born in, then I have bad news for almost all of the Americans in the audience. Probably quite a lot of the English too, though with less certainty as nobody's quite sure when even the Celts arrived.
Why don’t stick with modern history and internationally recognized borders? Forget about the deeds of the long gone people, they are not around so it’s irrelevant.
