Union and Its Territory: Articles 1 to 4 of the Indian Constitution

Understanding the Union of States, Territory of India, Reorganisation of States, and Evolution of States and Union Territories

The Constitution of India explains how the country is organised, who controls its territory, and how its states can be formed or changed. Part I of the Constitution, containing Articles 1 to 4, deals with the Union and its territory. These Articles are important because they describe India as a Union of States, classify its territory, and give Parliament the power to redraw state boundaries or create new states. This chapter explains these rules in a simple way, along with the historical journey through which modern Indian states and union territories developed after .

🎯 In this chapter, you will understand:

  • The meaning of Union of States and why India is not called a federation.
  • How the territory of India is classified under Article 1.
  • The powers of Parliament under Articles 2 and 3 to admit, create, and reorganise states.
  • How princely states were integrated and how linguistic states were formed after independence.

💡 Why this topic matters: This topic explains the constitutional foundation of India’s political map. It helps students understand how states are made, renamed, divided, or merged, and why the Union is stronger than individual states in matters of territory.

🧠 Core Idea: India is an indestructible Union of destructible states. The country remains one united whole, while Parliament can change the boundaries, names, and areas of states without needing their consent.

Union and Its Territory

The phrase Union and its Territory refers to the constitutional arrangement through which India is organised as one country made up of several states and union territories. The Constitution does not treat India as a loose collection of independent states. Instead, it presents India as a single, united political unit, with states functioning as important parts of that whole. This arrangement helps maintain national unity while allowing different regions to be governed through their own state governments.

  • Articles 1 to 4 under Part-I of the Constitution

    Articles 1 to 4 appear in Part I of the Constitution and form the legal basis for India’s territorial structure. They explain the name of the country, the nature of the Union, the classification of Indian territory, and the power of Parliament to make changes related to states. These provisions are foundational because every discussion about state formation, boundary changes, or the creation of union territories begins here.

    • These provisions govern the structure, name, and composition of the Union of India along with its territory.
  • Union of States

    Article 1 officially describes India as a Union of States. This means that India is not merely a group of separate units that came together by agreement. Rather, it is one country whose states remain within a common constitutional framework. The use of the word Union was a careful choice made by the Constitution-makers to show that India’s unity is permanent and central to its political system.

    • Article 1 officially defines India — Bharat — as a ‘Union of States’, not a ‘Federation of States’.
      • This statement addresses two essential aspects:
        • (i) The name of the country
        • (ii) The nature of its political structure
      • The Constituent Assembly debated extensively over whether to adopt the ancient name Bharat or the modern name India. Ultimately, it embraced both, resulting in the formulation — “India, that is, Bharat”. This compromise respected India’s long historical and cultural identity while also accepting the name commonly used in modern political and international affairs.
      • Although the Constitution is federal in nature, the term ‘Union’ was deliberately chosen.
        • (i) Dr. B. R. Ambedkar argued that the Indian Union did not emerge from an agreement between states, unlike the American Federation. In other words, Indian states did not first exist independently and then decide to join together; instead, the Union was already established, and states were organised within it.
        • (ii) States do not have a legal right to secede, meaning they cannot legally separate from India and become independent countries. The Union is indestructible and exists as an integrated whole for administrative convenience.
  • Classification of the Territory of India

    The territory of India includes more than just the areas governed by state governments. Article 1 divides Indian territory into different categories so that every part of the country has a clear constitutional status. This classification is important because states, union territories, and acquired territories are administered in different ways.

    • Under Article 1, India’s territory is grouped into:
      • (i) Territories of the states
      • (ii) Union territories
      • (iii) Territories that may be acquired by the Government of India in the future
    • The First Schedule of the Constitution lists the names and extents of states and union territories. Currently, there are 29 states and 7 union territories.
    • Special constitutional provisions apply to certain states — Maharashtra, Gujarat, Nagaland, Assam, Manipur, Andhra Pradesh, Telangana, Sikkim, Mizoram, Arunachal Pradesh, Goa, and Karnataka — which override general rules under Part XXI. These special provisions recognise the unique historical, social, administrative, or regional needs of these states.
    • Additionally, the Fifth and Sixth Schedules detail the governance of scheduled areas and tribal regions within states. These schedules provide special administrative arrangements to protect the interests of tribal communities and manage their local affairs carefully.
    • The expression ‘Territory of India’ is broader than ‘Union of India’ — the latter includes only states, while the former also covers union territories and any future acquisitions. Therefore, every union territory is part of the Territory of India, but it is not part of the Union of India in the narrow constitutional sense.
  • Administration and Control

    States and union territories are both part of India, but they are governed differently. States have their own elected governments and legislatures, which allow people in each state to participate in making laws and decisions for their region. Union territories, however, are more closely connected to the Central Government because they are administered directly by it, although some union territories have legislatures or special arrangements.

    • States function as members of the federal system, sharing powers with the Centre.
    • Union territories and acquired lands, however, are administered directly by the Central Government.
  • Acquisition of Territories

    India is a sovereign nation, which means it has full authority over its internal and external affairs. As a sovereign country, India can acquire new territory through methods accepted under international law. Such acquisition changes the physical extent of the country and may require constitutional or legal steps to integrate the new area into India’s administrative system.

    • Being a sovereign nation, India can acquire foreign lands through modes recognised by international law:
      • (i) Cession — via treaty, purchase, gift, lease, or plebiscite
      • (ii) Occupation — of previously unclaimed territories
      • (iii) Conquest or subjugation
    • Since the Constitution’s commencement, India has integrated territories like Dadra and Nagar Haveli, Goa, Daman and Diu, Puducherry, and Sikkim. These examples show how India’s political map has changed over time through accession, integration, and constitutional recognition.
  • Powers of the Parliament under Articles 2 and 3

    Parliament has special powers to change the political map of India. These powers are divided between Article 2 and Article 3. Article 2 mainly deals with bringing outside territories into the Indian Union, while Article 3 deals with adjusting the internal boundaries and organisation of existing states. Understanding this difference is essential for constitutional exams and for understanding how India’s states have evolved.

    • Article 2 grants Parliament:
      • (i) The authority to admit already existing states into the Union
      • (ii) The authority to create entirely new states
    • Article 3 concerns the internal reorganisation of territories within existing states of the Union.
    • Key difference: Article 2 deals with entities outside the Union; Article 3 manages changes within.
📌 Points to remember: India is a Union of States, not a federation formed by an agreement among states. The Territory of India is wider than the Union of India because it includes states, union territories, and territories that may be acquired in the future.

Parliament’s Power to Reorganise the States

Parliament can change the boundaries, areas, and names of states under the Constitution. This power allows the central government to respond to administrative needs, linguistic demands, regional aspirations, and changes in territory. However, this power is not unlimited; it must be exercised through a proper parliamentary procedure and according to constitutional rules.

Parliament can alter state boundaries, areas, and names under Article 3.
  • Scope of Article 3

    Article 3 gives Parliament wide authority to reshape the internal political map of India. It allows Parliament to respond to demands for new states, correct impractical boundaries, or give a state a new name. These powers make the Indian Union flexible, because the country can adjust its internal divisions without disturbing the unity of the nation.

    • Article 3 of the Constitution authorises the Parliament to reshape the map of India by altering state boundaries, names, and areas, or by forming entirely new states.
    • The specific powers granted include:
      • (i) Creating a new state by separating territory from an existing state, merging two or more states or parts thereof, or adding a territory to any state.
      • (ii) Enlarging the area of a state.
      • (iii) Reducing the area of a state.
      • (iv) Changing state boundaries.
      • (v) Renaming a state.
  • Conditions for Parliamentary Action

    Parliament cannot introduce a bill to reorganise states in the same way it introduces an ordinary bill. The Constitution requires the President’s prior recommendation before such a bill is introduced. This procedure ensures that the central government carefully considers the proposal before it reaches Parliament.

    • A bill proposing such changes can be introduced only with the President’s prior recommendation.
    • Before granting this recommendation, the President must refer the bill to the concerned State Legislature to seek its opinion within a set timeframe.
    • The President is not bound by the State Legislature’s opinion and can accept or reject it regardless of the content or timing. Thus, the state’s view is important, but it is advisory rather than binding.
    • No fresh reference is needed if amendments to the bill are made and approved in Parliament.
    • In the case of a Union Territory, Parliament can directly act without consulting any legislature.
  • Extent of Authority

    The power of Parliament under Article 3 is very strong. It shows that the Indian Constitution gives greater importance to national unity than to the separate existence of individual states. A state may be divided, merged, renamed, or have its boundaries changed, but the Union itself continues to exist.

    • The Constitution empowers Parliament to reorganise states without their consent, meaning the Union’s integrity is absolute while states’ existence is not constitutionally guaranteed.
    • India is described as “an indestructible union of destructible states”, in contrast to the USA, which is termed “an indestructible union of indestructible states” because its federal government cannot alter a state’s boundaries without its consent.
  • Article 4 Provisions

    Article 4 makes the process of state reorganisation simpler. It clarifies that laws made under Articles 2 and 3 for admitting, creating, or altering states are not treated as constitutional amendments. This means Parliament does not need to follow the difficult special procedure used for amending the Constitution.

    • Laws under Articles 2 and 3, concerning admission, establishment, or alteration of states, are not constitutional amendments under Article 368.
    • Such laws require only a simple majority and follow the ordinary legislative process.
  • Key Supreme Court Decisions

    The Supreme Court has explained the limits of Parliament’s power to change Indian territory. Its decisions distinguish between internal reorganisation of states and the transfer of Indian land to a foreign country. This distinction is important because giving away national territory affects the sovereignty of India and therefore requires a stronger constitutional procedure.

    • In , the Court ruled that diminishing a state’s area under Article 3 does not include ceding Indian territory to a foreign country — this requires a constitutional amendment under Article 368.
    • This decision arose when the Government decided to transfer part of Berubari Union (West Bengal) to Pakistan, leading to the enactment of the 9th Constitutional Amendment Act ().
    • In , the Court clarified that settling a boundary dispute with another country could be done via executive action if it did not involve cession of Indian territory.
  • The 100th Constitutional Amendment Act, 2015

    The 100th Constitutional Amendment Act, 2015 was a major step in settling India’s long-standing border issues with Bangladesh. It implemented the Land Boundary Agreement by allowing the exchange of enclaves and the resolution of disputed border areas. The amendment made the agreed territorial changes legally effective within India’s constitutional framework.

    • Implemented the Land Boundary Agreement between India and Bangladesh, enabling the exchange of enclaves, resolution of adverse possessions, and demarcation of a 6.1 km border stretch.
    • Under this agreement:
      • (i) India transferred 111 enclaves to Bangladesh.
      • (ii) Bangladesh transferred 51 enclaves to India.
    • The amendment altered the territorial provisions of Assam, West Bengal, Meghalaya, and Tripura in the First Schedule of the Constitution.
  • Historical Background of the Amendment

    The India–Bangladesh border dispute developed from the complex history of partition and the drawing of boundaries in . Over the years, several agreements and commissions attempted to solve problems related to enclaves, undemarcated stretches, and adverse possessions. The 100th Amendment finally gave constitutional effect to a long-negotiated solution.

    • (i) India and Bangladesh share a border of approximately 4,096.7 km. The original India–East Pakistan boundary was drawn under the Radcliffe Award (), but disputes led to the Bagge Award () and the Nehru–Noon Agreement ().
    • (ii) The Supreme Court ruling on Berubari Union led to the 9th Amendment Act (), though it was never notified for certain East Pakistan territories.
    • (iii) On , India and Bangladesh signed an agreement for boundary demarcation. Since it involved territory transfer, ratification required a constitutional amendment. This was supplemented by a Protocol on 6 September 2011 addressing un-demarcated boundaries, adverse possessions, and enclave exchange, prepared with the consent of the governments of Assam, Meghalaya, Tripura, and West Bengal.
📌 Points to remember: Article 3 allows Parliament to reorganise states without their consent, but ceding Indian territory to another country requires a constitutional amendment under Article 368.

Evolution of States and Union Territories

The states and union territories of India did not appear in their present form immediately after independence. India inherited a complicated political structure from British rule, consisting of provinces, princely states, and centrally administered areas. Over time, these units were integrated, reorganised, and reshaped to create a more efficient and democratic system of governance.

Historical map showing integration of princely states and reorganisation of Indian states
India’s states evolved through integration, linguistic demands, and the States Reorganisation Act, 1956.
  • Integration of Princely States

    At the time of independence, India was not a single unified political map. It contained areas directly ruled by the British and many princely states ruled by local kings and chiefs. The challenge after was to bring these different units into one democratic Union. This process required diplomacy, negotiation, and in some cases firm administrative action.

    • At the time of India’s independence, the country consisted of two categories of political units:
      • (i) British provinces — directly ruled by the British Government
      • (ii) Princely states — governed by native rulers under the paramountcy of the British Crown
    • The Indian Independence Act, 1947 created two separate dominions — India and Pakistan — and granted princely states three choices:
      • (i) Join India
      • (ii) Join Pakistan
      • (iii) Remain independent
    • Of the 552 princely states within India’s territory, 549 acceded to India while Hyderabad, Junagarh, and Kashmir initially refused.
      • Hyderabad was annexed through ‘police action’
      • Junagarh merged after a public referendum
      • Kashmir joined via the Instrument of Accession
    • By , the Constitution classified Indian states into four categories:
      • (i) Part A — 9 former governor’s provinces
      • (ii) Part B — 9 former princely states with legislatures
      • (iii) Part C — 10 chief commissioner’s provinces and some princely states, centrally administered
      • (iv) Part D — only Andaman and Nicobar Islands
  • Dhar Commission and JVP Committee

    After integration, people in many regions demanded that states be formed on the basis of language. They believed that people speaking the same language would find it easier to communicate, receive education, and take part in administration. However, the early committees worried that language alone could create divisions, so they recommended a more cautious approach.

    • The initial integration of princely states was an ad hoc arrangement, sparking demands — especially from southern India — for linguistic reorganisation of states.
    • In , the Linguistic Provinces Commission under S. K. Dhar was appointed to study the issue.
      • Submitted its report in
      • Recommended reorganisation based on administrative convenience rather than language
    • Public discontent led to the formation of the JVP Committee in , comprising Jawaharlal Nehru, Vallabhbhai Patel, and Pattabhi Sitaramayya.
      • Reported in
      • Rejected language as the sole criterion for reorganisation
    • Despite this, in October 1953, the first linguistic state — Andhra — was formed by separating Telugu-speaking regions from Madras State, following the death of Potti Sriramulu after a 56-day hunger strike.
  • Fazl Ali Commission

    The creation of Andhra showed that the demand for linguistic states could not be ignored. As similar demands grew in other regions, the Government appointed the States Reorganisation Commission to study the issue in a balanced way. The Commission recognised language as an important factor but also warned that national unity, security, and administrative efficiency could not be neglected.

    • The creation of Andhra state intensified demands for linguistic reorganisation, prompting the appointment of the States Reorganisation Commission in .
      • Chairman: Fazl Ali
      • Members: K. M. Panikkar and H. N. Kunzru
    • Report submitted in :
      • Accepted language as a basis, but not the ‘one language–one state’ principle
      • Stressed unity of India as the foremost criterion
      • Proposed four guiding factors:
        • (i) Preservation of national unity and security
        • (ii) Linguistic and cultural homogeneity
        • (iii) Economic, financial, and administrative viability
        • (iv) Welfare and development of people and the nation
    • Recommended abolishing the four-fold classification of states and creating:
      • (i) 16 states
      • (ii) 3 centrally administered territories
    • The Government of India accepted the proposal with minor changes.
      • The States Reorganisation Act, 1956 and 7th Constitutional Amendment removed the Part A/B distinction and abolished Part C states
      • Result: 14 states and 6 union territories formed on
  • Major Territorial Changes in 1956

    The reorganisation of created a new political map of India. It merged several former princely states and provinces into larger, more manageable states. Many of these changes were based on language, but they also considered geography, administration, and the need to preserve national unity.

    • Kerala formed by merging Travancore–Cochin State with Malabar District of Madras and Kasargod from South Canara.
    • Andhra Pradesh created by merging Telugu-speaking areas of Hyderabad State with Andhra.
    • Madhya Pradesh formed by combining Madhya Bharat, Vindhya Pradesh, and Bhopal.
    • Bombay State expanded by merging Saurashtra and Kutch.
    • Mysore State incorporated Coorg.
    • Punjab State merged with Patiala and East Punjab States Union (PEPSU).
    • Rajasthan absorbed Ajmer State.
    • Union Territory of Laccadive, Minicoy and Amindivi Islands created from areas taken from Madras State.
📌 Points to remember: The Fazl Ali Commission accepted language as one basis for state formation but gave first importance to national unity. The States Reorganisation Act, 1956 created 14 states and 6 union territories.

📝 Summary

Articles 1 to 4 of the Constitution establish India as a Union of States and define the territorial framework of the country. India is called a Union because its states are not independent units that can leave the country; they remain parts of one national whole. Parliament has strong powers under Articles 2 and 3 to admit new states, create states, and change their boundaries, areas, or names. However, transferring Indian territory to another country requires a constitutional amendment, as clarified in the Berubari case. The modern map of India developed through the integration of princely states, demands for linguistic states, the work of the Dhar Commission, JVP Committee, and Fazl Ali Commission, and the States Reorganisation Act, 1956.
