India as a "Union of States" — how territory can be added, altered, or reorganised under Articles 1-4, and who is a citizen of India under Articles 5-11, the Citizenship Act 1955, and the CAA 2019.
Part I (Articles 1-4) and Part II (Articles 5-11) of the Constitution together lay the foundation of the Indian state — first defining what India is (a Union of States, and how its territory can change) and then defining who belongs to it (the rules of citizenship at the commencement of the Constitution and thereafter). Both topics are compact but extremely high-yield for UPSC Prelims and Mains, especially in the form of Article-matching and statement-based questions.
Parliament may by law admit into the Union, or establish, new states on such terms and conditions as it thinks fit. This deals with the admission/establishment of areas outside India (e.g., Sikkim's earlier associate-state status before becoming a full state).
Parliament may by law:
Note: This same simple-majority procedure is why Parliament can reorganise states without invoking Article 368.
Laws made under Articles 2 and 3 must provide for amendment of the First Schedule (names/territories of states) and Fourth Schedule (Rajya Sabha seat allocation), and for supplemental, incidental, and consequential matters. Such laws are not treated as amendments to the Constitution under Article 368, even though they change the First/Fourth Schedules.
| Body / Event | Year | Key Outcome |
|---|---|---|
| Dhar Commission | 1948 | Recommended reorganisation on administrative convenience, not language |
| JVP Committee (Nehru, Patel, Pattabhi Sitaramayya) | 1948-49 | Rejected language as the sole basis for reorganisation |
| Formation of Andhra State | 1953 | First linguistic state, carved out of Madras after Potti Sriramulu's fast unto death |
| Fazl Ali Commission (States Reorganisation Commission) | 1953-55 | Recommended reorganisation broadly on linguistic lines |
| States Reorganisation Act | 1956 | Created 14 states and 6 Union Territories; came alongside the 7th Constitutional Amendment |
India follows the concept of single citizenship — unlike the USA, which has dual citizenship (of the country and of the state). Every Indian, irrespective of the state of birth or residence, is a citizen of India alone, and enjoys the same rights across the country (except limited special provisions such as domicile-based reservations or Article 370's erstwhile special status for J&K).
| Article | Provision |
|---|---|
| Article 5 | Citizenship at the commencement of the Constitution (26 Jan 1950) — based on domicile in India |
| Article 6 | Citizenship rights of persons who migrated to India from Pakistan |
| Article 7 | Citizenship rights of persons who migrated to Pakistan but later returned to India on a resettlement permit |
| Article 8 | Citizenship rights of persons of Indian origin residing outside India |
| Article 9 | A person who voluntarily acquires citizenship of a foreign state is not a citizen of India |
| Article 10 | Continuance of the rights of existing citizens, subject to any law made by Parliament |
| Article 11 | Empowers Parliament to make any provision regarding acquisition and termination of citizenship, and all matters relating to it |
| Mode | Key Condition |
|---|---|

| By Descent | Born outside India to Indian citizen parent(s); registration with an Indian consulate may be required depending on the birth year |
| By Registration | Certain categories (e.g., persons of Indian origin ordinarily resident in India for 7 years, spouses of Indian citizens) may apply for registration with the Central Government |
| By Naturalisation | A foreigner (not an illegal migrant) may apply after ordinarily residing in India for a specified period and fulfilling other conditions under the Third Schedule of the Act |
| By Incorporation of Territory | If a new territory becomes part of India, the Government of India specifies who among its people shall be citizens (e.g., Goa, Sikkim, Pondicherry) |
