Answer:
Cultural Region
Explanation:
A cultural region is basically a geographic area in which the people have common traits. The people have always grouped themselves, and the basis for it has been their culture and their physical appearance.

That has created sense of unity, which has created strong bonds among the people of a particular cultural region, so even if they do not personally all know each other, they are often willing to fight together for their rights, freedom, or interests, and even give their life for it.
