Devolution is the statutory granting of powers from the central government of a sovereign state to govern at a subnational level, such as a regional, local, or state level. It is a form of decentralization. Devolved territories have the power to make legislation relevant to the area. Devolution differs from federalism in that the devolved powers of the subnational authority may be temporary and ultimately reside in central government, thus the state remains, de jure unitary.
Federalism is a division of power between the federal government and the individual state governments. Devolution is specifically based on new federalism, which is a form of federalism that allows the states to reclaim some power while recognizing the federal government as the highest governmental power.evolution is the transfer of certain powers from one entity to another. It became popular in the 1970s and 1980s as an effort to reduce federal government powers by transferring some responsibilities to the state governments. Devolution is related to federalism.
