Discuss the dual objectives of federalism

As federalism has two or more levels of governments it has dual objectives.
(i) to safeguard and promote unity of the country.
(ii) and to accommodate regional diversity.
=> These two aspects are crucial for the institution and practice of federalism. The government at different levels should agree to some rules of power sharing.
=> They should also trust that each would abide by its part of agreement.
Hence, an ideal federal system has both aspects i.e., • Mutual trust and • Agreement to live together.
