. Why and how is power divided and shared among national,state, and local governments?

Power is divided among national, state, and local governments to ensure a balance of authority and address diverse needs. This division, known as federalism, helps prevent the concentration of power, promotes efficiency, and allows governments to address issues specific to their jurisdiction. National governments handle overarching matters, states manage shared responsibilities, and local governments address community-specific concerns. This structure aims to provide effective governance while respecting regional differences and promoting citizen involvement.
