Federalism is a system of government where power is divided between a central authority and constituent units. In India, power is shared between the central and state governments according to the constitution. The key features of federalism in India include a division of powers listed in the Union, State, and Concurrent lists. States have been reorganized along linguistic and cultural lines, and special status has been granted to some. Federalism has largely succeeded in India due to the creation of linguistic states, language policy protections, and evolving center-state relations.
