Regionalism (politics)
Regionalism is a political ideology that seeks to increase the political power, influence and self-determination of the people of one or more subnational regions. It focuses on the "development of a political or social system based on one or more" regions, and/or the national, normative, or economic interests of a specific region, group of regions or another subnational entity, gaining strength from or aiming to strengthen the "consciousness of and loyalty to a distinct region with a homogeneous population", similarly to nationalism.
