The Indian Constitution follows the federal system. This is what article 1 states: “India that is Bharat shall be a Union of States.” When India became free on 15 August 1947, the integration of the Princely, States became necessary. Our Federation did not come into existence through an agreement among existing States. It is a creation of the self-identity of the Indian people through the Constitution. The American Federal system came into existence as the result of an agreement among 13 colonies. Today America is Federation of 50 States.
