India had emerged as an independent nation after a painful and bloody partition.
Soon after independence, several princely states became a part of the country.
The Constitution declared India as a Union of States.
Although it did not use the word federation, the Indian Union is based on the principles of federalism.
The Constitution originally provided for a two-tier system of government, the Union government or Central government, representing the Union of India and the State governments.
Later, a third tier of ‘Panchayati Raj’ or local government was added.
