Federalism

Explanation:

Federalism is a system of government in which the power and responsibility of a geographical area are shared between a central authority (like a national government) and a number of states. The Federal System varies from country to country as some give more power to the states and less to the government and vice-versa. Either way, countries with this form of government usually have a Constitution that serves as a guideline to regulate the two government's actions and powers and to resolve disputes between them.
