What Is Federalism?
Federalism is a system of the government that divides power between the states and the Federal Government; used to structure the Constitution. For example the voting age is set by federal law and the speed limit is set by state law. Another example of federalism would be the United States because we have a strong central government. A central government is a government of a "nation-state and is more typically a characteristics of a unitary state".
