In politics, regionalism is a political ideology that focuses on the notional or normative interests of a particular region, group of regions or another subnational entity. These may be delineated by political divisions, administrative divisions, cultural boundaries, linguistic regions, and religious geography, among others. Regionalists, in the strict sense of the term, favor confederations over unitary nation states with strong central governments. They may, however, espouse also intermediate forms of federalism.
