I think it is very fitting to use the start of the colonization efforts as a starting point for a colonial conflict. Starting with a compromise efforts should really prompt the question: What were they comprising on? Starting with indigenous resistance against colonization should prompt the question: Who was colonizing whom? When did the colonization start?

Starting before the colonization project started and finding reasons or justifications for the colonization is only ever gonna be an exercise in justifying oppression. The victims of colonization had nothing to do with that. Conflicts start when the indigenous population resists colonial oppression.
