What is the concept of federalism?

The concept of federalism is fundamentally about the division of powers among different levels of government, specifically local, state, and federal governments. This structure allows each level of government to operate independently and have authority over certain areas, helping to balance power and prevent any one entity from becoming too powerful.

Federalism serves to not only recognize the distinct roles and responsibilities of different governmental layers, but it also promotes a system of checks and balances. For example, state governments can address local issues more effectively, while the federal government can manage broader national concerns. This distribution of power ensures that government remains responsive to the needs of its citizens at various levels.

In contrast, the other options represent different concepts. The separation of powers refers to the division of governmental responsibilities among different branches (executive, legislative, and judicial) within the same level of government, usually associated with national governance. The unification of government powers contradicts the principle of federalism, as it implies a consolidation rather than a division. Concentrating powers in the national government also goes against the essence of federalism, which aims to balance power across different governmental tiers rather than centralizing it.
