x1, in aspect x2, reflects the culture/lifestyle/people of a non-native (immigrant/invading/alien) population/culture x3 which at least partially but significantly and somewhat permanently (having established itself) locally supplanted, displaced, or dominated the indigenous/native culture x4 in region x5 (location)
Native American cultures (rindo) would qualify as x3, with x5 being a superset of the Americas (bemjoitco), whereas the Euramerican cultures that replaced them would be x3. Foreignness/indigenosity are not sufficient; the foreign population (and, even more importantly, culture) must come to dominate the indigenous one, at least locally.
