Abstract
In its narrower sense, federalism refers to the division of authority and function between and among the national government and the various state governments. Or the distribution of power in an organization (such as a government) between a central authority and the constituent. It’s a form of government in which power is held partly by a central authority and partly by a number of regional or state governments. Federalism has evolved over the course of American history. At different points in time, the balance and boundaries between the national and state government have changed substantially. In the twentieth century, the role of the national government expanded dramatically, and it continues to expand in the twenty-first century.
