The principle of federalism operates by distributing power between central and regional governments, allowing for a division of responsibilities and authority within a state. This system enables local governments to address community-specific needs while ensuring that national interests are also represented. By balancing powers, federalism promotes democratic participation and accountability at multiple governance levels. It cultivates diversity and encourages tailored solutions, as different regions can implement policies that reflect their unique contexts. However, federalism can also lead to challenges such as inconsistencies in policy implementation and tensions between different government levels.
