The Constitution of India provides for a single and uniform citizenship for the whole of India. Every person who was at the commencement of the Constitution (26 January 1950) domiciled in the territory of India and: (a) who was born in the territory of India or (b) either of whose parents was born in the territory of India or (c) who has been ordinarily resident in the territory of India for not less than five years immediately preceding such commencement, shall be a citizen of India. The Citizenship Act, 1955 provides for acquisition and termination of citizenship after the commencement of the Constitution.

The Constitution offers all citizens, individually and collectively, some basic freedoms. These are guaranteed in the Constitution in the form of six broad categories of Fundamental Rights which are justiciable.
