Answer: A federal system of government is one that divides the powers of government between the national (federal) government and state and local governments.

A national government is the government, or political authority, that controls a nation. At minimum, a national government requires a national army, enough power over its states or provinces to set and maintain foreign policy, and the ability to collect taxes.
