The political map of India is not a frozen artefact of 1950 but a living constitutional document, redrawn more than a dozen times by Parliament under a power so sweeping that one State can be erased and another conjured into existence by an ordinary law. For the judiciary aspirant, this topic sits precisely where physical geography meets constitutional law: you must know that India today comprises 28 States and 8 Union Territories, but you must equally know why Article 1 calls this a "Union of States" rather than a federation, how Articles 2 to 4 let Parliament reshape the federal map at will, and which Supreme Court decisions police the outer limits of that power. This chapter maps the territory and the law together, the way examiners ask it.
Article 1: India, that is Bharat, a Union of States
The starting point is the opening clause of the Constitution. Article 1(1) declares that "India, that is Bharat, shall be a Union of States." The deliberate choice of the word "Union" over "Federation" was explained by Dr B.R. Ambedkar in the Constituent Assembly: the Indian Union is not the result of an agreement among the units, and the units have no right to secede from it. Unlike the United States, whose states pre-existed and bargained their way into a compact, the Indian States are creatures of the Constitution and of Parliament. This indestructible-Union-of-destructible-States character is the single idea from which the entire law of state reorganisation flows.
Article 1(2) and 1(3) then define the territory of India in three distinct categories: (a) the territories of the States; (b) the Union Territories specified in the First Schedule; and (c) such other territories as may be acquired. The phrase "territory of India" is therefore wider than the "Union of India", because it embraces not only the States that share federal sovereign functions but also centrally administered Union Territories and any future acquired territory. The First Schedule is the authoritative ledger: it lists, by name and territorial description, every State and Union Territory, and it is this Schedule that Parliament edits each time the map changes. To understand how that map relates to the land itself, read this chapter alongside India — Physical Features.
The third category, acquired territory, is more than a theoretical possibility. When India acquired former French and Portuguese possessions such as Puducherry and Goa, the question arose whether mere acquisition automatically made them part of the territory of India. The settled position is that acquisition under international law (by treaty, cession or conquest) vests title in the Union, but the territory becomes a constituent part of India only when Parliament so provides by editing the First Schedule. Sovereignty over acquired territory is a political fact; its place on the constitutional map is a legislative act. This two-step logic, acquire first, then absorb by statute, is the same mechanism that underpins every internal reorganisation, and it is why Article 1 is best read as the index to Articles 2 to 4 rather than a standalone declaration.
Articles 2, 3 and 4: The Power to Redraw the Map
The constitutional machinery for changing the map lives in three short articles. Article 2 empowers Parliament to admit into the Union, or establish, new States on such terms as it thinks fit; this deals with territory outside the existing Union (for example, the integration of Sikkim was ultimately effected through constitutional amendment, but the admission power illustrates Article 2's reach). Article 3 is the workhorse: it allows Parliament, by ordinary law, to form a new State by separation of territory, to increase or diminish the area of any State, to alter boundaries, and to alter the name of any State. Article 4 then provides that any law made under Articles 2 or 3 may amend the First and Fourth Schedules and is not to be deemed a constitutional amendment under Article 368, meaning a simple majority suffices.
The constitutional significance is profound: the federal map of India can be altered without the special-majority, ratification-by-States safeguard that protects other parts of the Constitution. A State has no veto over its own dismemberment. This is the textual heart of what scholars call India's "holding-together" federalism, and it is why understanding the political map is inseparable from understanding constitutional law.
It is worth dwelling on the contrast with the United States and Australia, where the boundaries of constituent units are entrenched and cannot be altered without the consent of the units concerned. The framers of the Indian Constitution consciously rejected that model. Having just witnessed Partition and the chaotic integration of more than five hundred princely states, they wanted a Centre strong enough to reshape the units in the national interest without being held hostage by any one of them. Article 3 is the institutional expression of that priority. The explanation appended to Article 3 makes the reach of the power even clearer: "State" in the article includes a Union Territory, but in the proviso it does not, so the consultation requirement does not apply when Parliament reorganises a Union Territory. That asymmetry is a favourite examiner trap and flows directly from the subordinate constitutional status of Union Territories.
The Proviso to Article 3 and Babulal Parate
Article 3 carries a proviso imposing two procedural conditions. First, no Bill for the purposes of Article 3 may be introduced in either House except on the recommendation of the President. Second, where the Bill affects the area, boundaries or name of a State, the President must refer the Bill to the Legislature of that State for expressing its views within a specified period. The scope of this proviso was authoritatively settled in Babulal Parate v. State of Bombay, AIR 1960 SC 51. There the Bill, after being referred to the Bombay Legislature, was substantially amended by Parliament before enactment as the States Reorganisation Act, 1956, and the petitioner argued that the amended Bill required a fresh reference.
The Supreme Court rejected the contention. It held that the proviso requires only an initial reference of the Bill to the State Legislature; Parliament is free to amend the Bill thereafter, even substantially, without referring it again. Crucially, the Court emphasised that Parliament is not bound to accept or act upon the views expressed by the State Legislature, and that if the Legislature fails to respond within the time allowed, that failure does not invalidate the Bill. Babulal Parate thus confirms parliamentary supremacy over the federal map: the State's voice is consultative, never decisive.
The Outer Limit: Re Berubari Union and Cession of Territory
If Article 3 lets Parliament freely redraw internal boundaries, can it also give away Indian territory to a foreign State? This was answered in the landmark Presidential reference In re Berubari Union and Exchange of Enclaves, AIR 1960 SC 845, decided under Article 143(1). The reference arose out of the Nehru-Noon Agreement of 1958, under which India agreed to cede part of the Berubari Union in West Bengal to Pakistan. The unanimous opinion, delivered by Justice Gajendragadkar, drew a sharp distinction.
The Court held that Article 3 authorises only the internal reorganisation of Indian territory; it does not empower Parliament to cede any part of Indian territory to a foreign State, because cession affects the sovereignty and territorial integrity of India itself. Such cession, the Court ruled, could be effected only by a constitutional amendment under Article 368, not by ordinary legislation under Article 3. The opinion directly led to the Constitution (Ninth Amendment) Act, 1960, which amended the First Schedule to give effect to the Berubari settlement. Berubari remains the foundational authority on the relationship between the federal map, sovereignty, and the limits of the Article 3 power.
The principle was applied again, decades later, in the implementation of the 2015 India-Bangladesh Land Boundary Agreement, which exchanged enclaves and adverse possessions along the eastern border. Faithful to Berubari, the Government did not attempt to implement that exchange by ordinary law; it secured the Constitution (One Hundredth Amendment) Act, 2015, amending the First Schedule, precisely because the transfer of territory to Bangladesh amounted to cession. The through-line from 1960 to 2015 is unbroken: redrawing internal lines is the business of Article 3 and a simple majority, but altering the international boundary so as to part with Indian soil demands the solemnity of a constitutional amendment. For the judiciary candidate, the comparison between the Ninth Amendment and the Hundredth Amendment is the cleanest illustration of the doctrine in action.
Linguistic Reorganisation: From Andhra State to the 1956 Act
At independence the inherited map was a patchwork of Part A (former Governor's provinces), Part B (former princely states), Part C and Part D territories. The demand to redraw this on linguistic lines crystallised when Potti Sriramulu's fast-unto-death led to the creation of Andhra State in 1953, the first State carved out on a purely linguistic basis from the Madras Presidency. This forced the Centre's hand. The States Reorganisation Commission (SRC) was appointed in December 1953 under the chairmanship of Fazl Ali, with H.N. Kunzru and K.M. Panikkar as members.
The SRC accepted language as an important but not exclusive criterion, expressly rejecting the slogan "one language, one state" and stressing national unity, security and administrative-financial viability. Its recommendations produced the States Reorganisation Act, 1956, which came into force on 1 November 1956 and abolished the Part A/B/C/D classification, reconstituting the country into 14 States and 6 Union Territories. This remains the single most extensive redrawing of India's internal boundaries, and the Bill that produced it was the very statute litigated in Babulal Parate. The linguistic logic of these boundaries broadly tracks the river-valley and plateau divisions explored in Indian River Systems and Drainage.
Post-1956 Evolution: A Map in Permanent Motion
The 1956 settlement did not end the redrawing; it merely set the template. Bombay was bifurcated into Maharashtra and Gujarat in 1960 on linguistic lines. Punjab was reorganised in 1966, separating Haryana and the hill areas of Himachal Pradesh, with Chandigarh becoming a Union Territory and the shared capital of Punjab and Haryana, an arrangement that endures to this day. The North-East was extensively reorganised by the North-Eastern Areas (Reorganisation) Act, 1971, giving statehood to Manipur, Tripura and Meghalaya and creating the Union Territories that would become Mizoram and Arunachal Pradesh.
Goa, liberated from Portuguese rule in 1961, became a Union Territory and was elevated to statehood in 1987 alongside the creation of Arunachal Pradesh and the elevation of Mizoram. Sikkim followed a distinctive route: it entered the Union first as an associate State through the Constitution (Thirty-fifth Amendment) Act, 1974, and then as a full State through the Constitution (Thirty-sixth Amendment) Act, 1975, the only State to be admitted by constitutional amendment rather than created by a reorganisation law under Article 3. Each of these changes was effected by Parliament editing the First Schedule, a vivid demonstration of the "destructible States" principle of Article 1. For the judiciary aspirant, the examinable point is consistency: almost every one of these reorganisations passed through the Article 3 procedure and survived constitutional scrutiny precisely because the State's consent was never required.
A useful way to organise this dense chronology is by motive. The 1953-to-1971 wave was driven overwhelmingly by language and ethnic identity, the 1987 changes by the maturing of frontier Union Territories into States, and the 2000 wave by development and administrative efficiency in large, unwieldy Hindi-belt States. Recognising the underlying rationale not only helps memorise the sequence but also answers the standard mains question on the "criteria for creating new States", where the expected answer threads the SRC's multi-factor test through each successive reorganisation rather than treating language as the sole determinant.
The Year 2000: Chhattisgarh, Uttarakhand and Jharkhand
The next great wave came in November 2000, driven not by language but by demands for administrative efficiency and the development of tribal and hill regions. Three States were created in quick succession through separate Reorganisation Acts. Chhattisgarh was carved out of Madhya Pradesh on 1 November 2000 (capital Raipur). Uttarakhand, initially named Uttaranchal, was separated from Uttar Pradesh on 9 November 2000 (capital Dehradun). Jharkhand was carved out of Bihar on 15 November 2000 (capital Ranchi).
These three creations took the count of States from 25 to 28. They are an examiner's favourite for sequencing questions, so the dates and parent States must be memorised precisely: Chhattisgarh from Madhya Pradesh, Uttarakhand from Uttar Pradesh, Jharkhand from Bihar. Geographically, all three are dominated by plateau, forest and mineral belts, which is why they appear again in Natural Resources of India as the heartland of India's coal, iron and bauxite reserves.
Telangana 2014: The 29th State
The most recent State to be created by carving out territory from another State is Telangana. After decades of agitation rooted in perceived regional neglect, the Andhra Pradesh Reorganisation Act, 2014 (Act 6 of 2014) bifurcated Andhra Pradesh, creating Telangana as the 29th State with effect from 2 June 2014. Telangana was constituted from ten districts of the erstwhile Andhra Pradesh, with Hyderabad as its capital.
The Act made a notable transitional arrangement under Article 3's flexibility: Hyderabad was designated the common capital of both Telangana and the residuary Andhra Pradesh for a period not exceeding ten years, after which it would remain the capital of Telangana while Andhra Pradesh established a new capital (Amaravati). The bifurcation was politically contentious and was challenged, but the courts have consistently treated the creation of a State as a legislative-political question within Parliament's Article 3 competence, echoing the Babulal Parate principle that the affected State's objections are not a veto.
Telangana repays close study because it compresses almost every doctrinal theme of this chapter into a single recent statute. The proviso to Article 3 was triggered: the Bill was referred to the Andhra Pradesh Assembly, which actually rejected it, yet under Babulal Parate that rejection had no legal effect on Parliament's competence to proceed. The Act also illustrates the breadth of "consequential" provisions a reorganisation law can carry: apportionment of assets and liabilities, division of the High Court, allocation of seats in Parliament and the State Legislatures, distribution of Krishna and Godavari river waters, and the unusual ten-year shared-capital arrangement for Hyderabad. Article 4 expressly authorises such supplemental, incidental and consequential provisions, which is why a single Act of ordinary law could re-engineer an entire State without any constitutional amendment. The river-water allocation dimension, in particular, ties this episode to the inter-State disputes discussed in Indian River Systems and Drainage.
Jammu and Kashmir 2019: A State Becomes Two Union Territories
The most constitutionally dramatic redrawing came in 2019. The Jammu and Kashmir Reorganisation Act, 2019, which received Presidential assent on 9 August 2019 and came into effect on 31 October 2019, did something unprecedented: it downgraded a full State into two Union Territories. The erstwhile State of Jammu and Kashmir was reconstituted into the Union Territory of Jammu and Kashmir (with a Legislative Assembly) and the Union Territory of Ladakh (without a Legislative Assembly), each headed by a Lieutenant Governor.
This was accompanied by Presidential orders rendering inoperative the special status under Article 370. The reorganisation reduced the number of States from 29 to 28 and increased the Union Territories. In In re Article 370 of the Constitution (2023), a Constitution Bench of the Supreme Court upheld the abrogation of Article 370 and declined to decide the validity of the State-to-UT conversion only because the Solicitor-General assured the Court that statehood would be restored, while the carving out of Ladakh as a UT was upheld. The episode is a stark reminder that under Article 3 read with Article 4, even the very statehood of a unit is at Parliament's disposal.
The 28 States and Their Capitals
For prelims, the names and capitals must be at your fingertips. The 28 States and their capitals are: Andhra Pradesh (Amaravati), Arunachal Pradesh (Itanagar), Assam (Dispur), Bihar (Patna), Chhattisgarh (Raipur), Goa (Panaji), Gujarat (Gandhinagar), Haryana (Chandigarh), Himachal Pradesh (Shimla), Jharkhand (Ranchi), Karnataka (Bengaluru), Kerala (Thiruvananthapuram), Madhya Pradesh (Bhopal), Maharashtra (Mumbai), Manipur (Imphal), Meghalaya (Shillong), Mizoram (Aizawl), Nagaland (Kohima), Odisha (Bhubaneswar), Punjab (Chandigarh), Rajasthan (Jaipur), Sikkim (Gangtok), Tamil Nadu (Chennai), Telangana (Hyderabad), Tripura (Agartala), Uttar Pradesh (Lucknow), Uttarakhand (Dehradun) and West Bengal (Kolkata).
Two trap-points recur in question papers. First, Chandigarh is the shared capital of both Punjab and Haryana, while itself being a Union Territory, a unique tripartite arrangement dating to the 1966 reorganisation. Second, several States operate a summer-winter capital system: Himachal Pradesh uses Dharamshala as a second (winter) seat, and Maharashtra holds a winter session at Nagpur, though Mumbai remains the constitutional capital. The distribution of these capitals across the Himalayan, plateau and coastal belts mirrors the relief described in India — Physical Features.
The 8 Union Territories
India presently has eight Union Territories: Delhi (the National Capital Territory), Puducherry, Jammu and Kashmir, Ladakh, Chandigarh, Andaman and Nicobar Islands, Lakshadweep, and Dadra and Nagar Haveli and Daman and Diu. The last of these is itself a product of reorganisation: the two former Union Territories of Dadra and Nagar Haveli and of Daman and Diu were merged into a single Union Territory with effect from 26 January 2020 by the Dadra and Nagar Haveli and Daman and Diu (Merger of Union Territories) Act, 2019, with Daman as its headquarters.
Two of the eight, Delhi and Puducherry, have their own Legislative Assemblies and Councils of Ministers under Articles 239AA and 239A respectively; the other six are administered directly by the President through Administrators. A current-affairs point examiners have begun to test: the capital of the Andaman and Nicobar Islands, Port Blair, was renamed Sri Vijaya Puram in September 2024 to shed its colonial association. Jammu and Kashmir retains Srinagar (summer) and Jammu (winter) as its seats, while Ladakh is administered from Leh.
Federal Character and the Limits of Judicial Review
The recurring jurisprudential theme is the tension between Parliament's plenary Article 3 power and the federal character of the Constitution recognised as part of the basic structure in Kesavananda Bharati v. State of Kerala, (1973) 4 SCC 225, and reaffirmed in S.R. Bommai v. Union of India, (1994) 3 SCC 1. While federalism is a basic feature, the Supreme Court has been careful never to convert it into a State's veto over reorganisation. The map remains Parliament's to draw; what the basic-structure doctrine protects is the existence of a meaningful federal scheme, not the boundaries of any particular State.
Thus the decided cases form a coherent architecture. Babulal Parate fixes the procedure and confirms that the State's views are merely consultative. Berubari fixes the outer substantive limit, that internal reorganisation is permissible by ordinary law but cession of territory needs a constitutional amendment. Bommai and the Article 370 reference supply the federal-character backdrop against which these powers are exercised. Together they explain why India's political map has changed so often yet so smoothly, and why a question on "states and the map" is, in a judiciary paper, really a question on constitutional law. For the wider geographical canvas on which these units sit, see the hub at Geography for Judiciary.
Exam Strategy: How This Topic Is Tested
In prelims, expect direct factual matching: state-to-capital, state-to-year-of-formation, parent-state pairings, and the count of States and Union Territories. The high-yield facts are the November 2000 trio with exact dates, Telangana 2014 as the 29th State, the J&K reorganisation of 2019 reducing States to 28, and the eight current Union Territories with the Delhi/Puducherry Assembly distinction. Current-affairs overlays such as the Port Blair renaming and the 2020 Dadra-Daman merger are increasingly common.
In mains and interview, the questions turn doctrinal: explain the scope of Article 3 and its proviso with reference to Babulal Parate; distinguish reorganisation from cession with reference to Berubari; and discuss whether the State-to-UT conversion of Jammu and Kashmir is consistent with federalism. The disciplined answer always links a geographical fact to its constitutional source: the map is the data, Articles 1 to 4 are the engine, and the case law is the brake. Master that triangle and this becomes one of the most scoring topics in the paper.
Frequently asked questions
How many States and Union Territories does India have today?
India currently has 28 States and 8 Union Territories. The count of States dropped from 29 to 28 when the Jammu and Kashmir Reorganisation Act, 2019, converted the State of Jammu and Kashmir into two Union Territories (J&K and Ladakh) with effect from 31 October 2019.
What is the difference between Article 2 and Article 3?
Article 2 empowers Parliament to admit or establish new States that are outside the existing territory of the Union (new entrants). Article 3 deals with the internal reorganisation of existing territory, forming new States by separation, altering areas, boundaries or names. Both can be done by ordinary law, and under Article 4 such a law amends the First Schedule without being a constitutional amendment.
What did the Supreme Court hold in Re Berubari Union?
In In re Berubari Union, AIR 1960 SC 845, the Court (per Gajendragadkar J.) held that Article 3 permits only internal reorganisation of Indian territory and does not authorise cession of Indian territory to a foreign State. Cession affects India's sovereignty and can be effected only by a constitutional amendment under Article 368, which led to the Ninth Amendment, 1960.
Does a State have to consent before it is reorganised?
No. Under the proviso to Article 3, the President must refer the Bill to the affected State Legislature for its views, but as held in Babulal Parate v. State of Bombay, AIR 1960 SC 51, Parliament is not bound by those views, may amend the Bill afterwards without a fresh reference, and may proceed even if the Legislature does not respond. The State has a voice, not a veto.
Which States were created in November 2000 and from where?
Three States were created in November 2000: Chhattisgarh (1 Nov, from Madhya Pradesh), Uttarakhand (9 Nov, from Uttar Pradesh) and Jharkhand (15 Nov, from Bihar). They raised the number of States from 25 to 28.
Why is India called a 'Union of States' and not a 'Federation'?
Article 1 deliberately uses "Union of States" to signal, as Dr Ambedkar explained, that the Union is not a contract among the units and that no State has a right to secede. The States derive their existence from the Constitution and can be reorganised by Parliament under Article 3, making India an indestructible Union of destructible States.
