Answer:
Federalism.
Step-by-step explanation:
Federalism is a government in which power is divided between state and national levels. One such example is the early Colonies which was an advocate of a federal union between the American colonies after the Revolution. One major problem was that the states competed with each other in an unproductive manner. Today, the Constitution has established a system of “dual sovereignty,” under which the States have surrendered many of their powers to the Federal Government, but also retained some sovereignty.
