Has there ever been any culture in the history of lands or cultures that has ever not been invaded or conquered willfully by another—or tried? Nobody's ever said, "let's check to see if anyone lives here first" unless that culture had superior numbers, technology, or weapons. All races, all species, all cultures, all faiths, and even revolts, protests, defiances are attempts to reconquer or expel the invaders—be it through violence or policy or law. Being a majority population always helps.
