Step-by-step explanation:
Federalism is a system of government that divides power over people and territory between a national government and regional levels of government. This means that certain powers are granted to the national government, while other powers are reserved for the state governments. The United States is an example of a federal system, where the national government handles matters that affect the entire country, such as defense and economic policy, while state governments handle matters within their own jurisdictions, like education and public safety.
