Subsequent: A subsequent boundary is one that develops after the cultural landscape has already been established, often as a result of conflicts or changes in political power.
Superimposed: A superimposed boundary is imposed on an existing cultural landscape by an outside force, disregarding the existing social and cultural patterns.
Relic: A relic boundary refers to a former political boundary that still holds some influence on the present-day cultural landscape, even though it may no longer serve any administrative purpose.
