As far as I know, the definition doesn't require the population to be "native". For example, history has plenty of cases of ethnic cleansing against Jewish people in Europe. Or at least Wikipedia considers it as such: https://en.wikipedia.org/wiki/Ethnic_cleansing

Also, the people that were "brought there against their will to work" were the 1800's ancestors of the people that were forcibly removed in the 1970's. How many centuries does it take for a group of people to gain the right against forceful displacement?
