Federalism, Devolution, and the Politics of Subnational Autonomy
Quick fact
In the United States, the Constitution grants states powers not explicitly delegated to the federal government, creating a dual-sovereignty system. Yet even in federal countries, the practice of devolution can vary, allowing some regions more autonomy than others, as seen with Scotland within the UK.
Why this is interesting
You live in a country where the most powerful leader can overrule your local government—yet in another country, your local parliament might hold veto power. Why do some regions get so much autonomy, and others none at all?
