Integration of the Princely States: Accession and PYQs
Notes on the integration of the princely states for competitive exams: lapse of paramountcy, Instrument of Accession, Junagadh, Hyderabad, Kashmir, Goa and Sikkim.
By GK24 Editorial Team· Published · 4 min read

British India on the eve of freedom was two countries in one. About three-fifths of the map was British territory, governed from the Secretariat in New Delhi through provinces and districts. The rest, around 565 princely states of wildly different size, from Hyderabad with its own railway and currency down to estates of a few villages, was ruled by princes who accepted the paramountcy of the British Crown and in return kept their thrones. When the Indian Independence Act, 1947 received the royal assent in July 1947, it did not transfer that paramountcy to India or to Pakistan. It simply lapsed it from 15 August 1947, leaving every state free in theory to accede to either dominion or to try to stand alone. Stitching this patchwork into one Union in little more than a year was the achievement of the States Department under Sardar Vallabhbhai Patel, with V. P. Menon as its Secretary, and it is the subject examiners return to whenever they want a question on the first years of the Republic.
The instruments used
- The Instrument of Accession was the key document. A ruler who signed it surrendered only three subjects to the new central government: defence, external affairs and communications. Everything else, for the moment, stayed with the state, which made signing far easier to accept.
- A Standstill Agreement ran alongside it, continuing existing arrangements on customs, railways, posts and currency until fresh ones were settled.
- Appeals to patriotism, generous privy purses and the plain argument that a landlocked state could not survive alone did the rest. By 15 August 1947 all but three states had signed.
The three that held back
| State | Ruler | How it was settled |
|---|---|---|
| Junagadh | Nawab Mahabat Khan III | Acceded to Pakistan in September 1947 though it was surrounded by Indian territory; popular resistance and the Nawab's flight were followed by a plebiscite in February 1948 that voted overwhelmingly for India |
| Hyderabad | Nizam Mir Osman Ali Khan | Signed a Standstill Agreement in November 1947 and then delayed; with the Razakar militia under Kasim Razvi terrorising the countryside, the Government of India moved in through the police action codenamed Operation Polo from 13 to 18 September 1948, and the Nizam acceded |
| Jammu and Kashmir | Maharaja Hari Singh | Hesitated until tribal raiders backed from across the border entered the valley in late October 1947; he signed the Instrument of Accession on 26 October 1947, after which Indian troops were airlifted to Srinagar |
From accession to integration
Accession only brought the states under the Union for three subjects. Integration, which followed in 1948 and 1949, actually dissolved most of them as separate units. Four patterns were used. Some states were merged into the neighbouring province, as the Orissa and Chhattisgarh states were. Some were grouped into new unions of states, which produced Saurashtra, Rajasthan, Madhya Bharat, Travancore-Cochin and the Patiala and East Punjab States Union, always shortened to PEPSU. Some became centrally administered areas, among them Himachal Pradesh, Vindhya Pradesh, Manipur and Tripura. Hyderabad, Mysore and Jammu and Kashmir remained single large units. When the Constitution came into force on 26 January 1950 this was frozen into four classes: Part A states, the former governors' provinces; Part B states, the former princely units headed by a Rajpramukh; Part C states, the chief commissioners' provinces and smaller princely areas; and Part D, the Andaman and Nicobar Islands. The classification lasted only until the States Reorganisation Act, 1956 replaced it.
The territories that came later
- French possessions. Chandernagore voted to join India and was transferred at the start of the 1950s. Pondicherry, Karaikal, Mahe and Yanam were handed over de facto on 1 November 1954, and the treaty of cession was ratified in 1962.
- Portuguese possessions. Dadra and Nagar Haveli were freed by volunteers in 1954. Goa, Daman and Diu were taken in the military action codenamed Operation Vijay, which ended on 19 December 1961, the date still kept as Goa Liberation Day.
- Sikkim was an Indian protectorate from 1950. After a referendum it became the twenty-second state of the Union by the 36th Constitutional Amendment Act, 1975.
Why Patel is remembered for it
Sardar Vallabhbhai Patel, born on 31 October 1875, took charge of the newly created States Department in early July 1947 and worked through V. P. Menon, whose account, The Story of the Integration of the Indian States, remains the standard source. The combination of persuasion in the drawing room and firmness in the last resort earned Patel the names Iron Man of India and Bismarck of India, after the chancellor who unified Germany. His birth anniversary, 31 October, is observed as Rashtriya Ekta Diwas, National Unity Day, and the Statue of Unity at Kevadia in Gujarat commemorates him. Patel died on 15 December 1950, less than a year after the Constitution he had helped to make came into force.
Exam Point of View
Three kinds of question come from this chapter. The first is the simple who and when: who headed the States Department, who was its Secretary, which three subjects the Instrument of Accession covered. The second is the trio of hold-outs, where the pairing of state with method is tested, Junagadh with a plebiscite, Hyderabad with Operation Polo, Kashmir with the Instrument of Accession of 26 October 1947; an examiner will often swap Operation Polo with Operation Vijay, which belongs to Goa in 1961. The third is the administrative map: Part A, B, C and D states, the meaning of Rajpramukh, the expansion of PEPSU, and the amendment that brought in Sikkim. Watch also for the statement-based question on the lapse of paramountcy, where the wrong option says that paramountcy passed to the Government of India.

Practice MCQs on this topic
Which leader headed the States Department created in 1947 to bring the princely states into the Indian Union?
- A.Jawaharlal Nehru
- B.Sardar Vallabhbhai Patel
- C.C. Rajagopalachari
- D.Maulana Abul Kalam Azad
Show answer
Correct answer: B. Sardar Vallabhbhai Patel
Explanation
The correct answer is B, Sardar Vallabhbhai Patel. The States Department was set up in early July 1947, weeks before independence, and Patel took charge of it as Deputy Prime Minister and Home Minister, with V. P. Menon as its Secretary. In little more than a year the department secured the accession of around 565 states and then merged most of them into provinces or unions of states. Option A is wrong: Nehru as Prime Minister handled foreign affairs and dealt personally with Kashmir, but the department was not his. Option C is wrong: C. Rajagopalachari became Governor-General in 1948 and later Chief Minister of Madras, and had no charge of the states question. Option D is wrong: Maulana Azad was Education Minister in the first cabinet. The work earned Patel the titles Iron Man of India and Bismarck of India, and his birth anniversary on 31 October is observed as National Unity Day.
Under the Instrument of Accession, a princely state transferred which three subjects to the Government of India?
- A.Defence, external affairs and communications
- B.Defence, taxation and police
- C.Currency, customs and railways
- D.Education, health and local government
Show answer
Correct answer: A. Defence, external affairs and communications
Explanation
The correct answer is A, defence, external affairs and communications. The Instrument of Accession was kept deliberately narrow so that a ruler could sign it without feeling that he had surrendered his state, and all other powers stayed with him for the time being. Option B is wrong: taxation and police remained with the states at the stage of accession, and were brought under common administration only through the later merger agreements. Option C names the matters covered not by the Instrument but by the Standstill Agreement, which continued existing arrangements on customs, currency, posts and railways until new ones were settled. Option D lists subjects that were never part of the document; they were and remain largely provincial or state subjects. The point to remember is the two-step process: a narrow accession in 1947, and the real integration into provinces, unions of states and centrally administered areas in 1948 and 1949.
Who was the Secretary of the States Department who worked with Sardar Patel on the integration of the princely states?
- A.H. M. Patel
- B.V. P. Menon
- C.K. M. Munshi
- D.B. N. Rau
Show answer
Correct answer: B. V. P. Menon
Explanation
The correct answer is B, V. P. Menon. As Secretary of the States Department he drafted the Instrument of Accession and the Standstill Agreement, travelled from court to court to collect signatures, and wrote the standard first-hand account of the episode, The Story of the Integration of the Indian States. Option A, H. M. Patel, was a senior civil servant who worked on the partition arrangements and later became a finance minister, but not on the states. Option C, K. M. Munshi, was a member of the Constituent Assembly and of its Drafting Committee, and was the agent-general in Hyderabad during the crisis, a related but different role. Option D, B. N. Rau, was the Constitutional Adviser to the Constituent Assembly, who prepared the first draft of the Constitution. Pairing Patel as the political head with Menon as the official head is the form in which this question is usually set.
The integration of Hyderabad into the Indian Union was completed through a police action with which code name?
- A.Operation Vijay
- B.Operation Polo
- C.Operation Meghdoot
- D.Operation Cactus
Show answer
Correct answer: B. Operation Polo
Explanation
The correct answer is B, Operation Polo. The Nizam of Hyderabad, Mir Osman Ali Khan, had signed a Standstill Agreement in November 1947 and then delayed accession while the Razakar militia under Kasim Razvi attacked villagers. The Government of India launched the police action from 13 to 18 September 1948, after which the Nizam acceded and became Rajpramukh of the state. Option A, Operation Vijay, was the action of December 1961 that ended Portuguese rule in Goa, Daman and Diu, and the name was used again in 1999 for the Kargil operations. Option C, Operation Meghdoot, was the 1984 operation on the Siachen glacier. Option D, Operation Cactus, was the Indian intervention in the Maldives in 1988. Examiners very often offer Operation Polo and Operation Vijay together, so fix the pairing of Polo with Hyderabad in 1948 and Vijay with Goa in 1961.
Maharaja Hari Singh signed the Instrument of Accession for Jammu and Kashmir on which date?
- A.15 August 1947
- B.26 October 1947
- C.26 January 1948
- D.17 September 1948
Show answer
Correct answer: B. 26 October 1947
Explanation
The correct answer is B, 26 October 1947. The Maharaja had hoped to stay out of both dominions and had signed a standstill arrangement, but when tribal raiders supported from across the border entered the valley and advanced towards Srinagar in late October 1947 he asked India for military help. India made accession the condition, the Instrument was signed on 26 October, and troops were airlifted to Srinagar the next day. Option A is wrong because no accession was signed on the day of independence; that is the date on which paramountcy lapsed. Option C, 26 January 1948, is close to the date the Constitution came into force two years later and has nothing to do with Kashmir. Option D, 17 September 1948, falls inside the Hyderabad police action, and is remembered in Telangana in connection with that event, not with Kashmir. The accession was later reflected in Article 370.
What did the Indian Independence Act, 1947 do with the paramountcy that the British Crown exercised over the princely states?
- A.Transferred it to the Government of India
- B.Divided it between India and Pakistan
- C.Allowed it to lapse from 15 August 1947
- D.Continued it for a further ten years
Show answer
Correct answer: C. Allowed it to lapse from 15 August 1947
Explanation
The correct answer is C. The Act let paramountcy lapse with effect from 15 August 1947, so in strict law every princely state became free either to accede to India, to accede to Pakistan, or to attempt to remain outside both. That is why the States Department had to obtain a signed Instrument of Accession from each ruler rather than simply inherit authority over them. Option A is the commonest wrong answer, and it is wrong precisely because no transfer took place; India's authority over a state came from the ruler's own accession. Option B is wrong for the same reason, and the Act drew a boundary between the two dominions without dividing paramountcy. Option D is wrong because the Act set no such period; the Chamber of Princes created in 1921 simply ceased to matter. The lapse is the fact on which statement-based questions in this chapter usually turn.
Junagadh finally joined the Indian Union after which event?
- A.A plebiscite held in February 1948
- B.A police action in September 1948
- C.An award of the Boundary Commission
- D.A referendum held in 1956
Show answer
Correct answer: A. A plebiscite held in February 1948
Explanation
The correct answer is A, a plebiscite held in February 1948. The Nawab of Junagadh, Mahabat Khan III, announced accession to Pakistan in September 1947 although his small state in Kathiawar was surrounded by Indian territory and had a largely Hindu population. Popular resistance followed, the Nawab left for Karachi, and after the administration was taken over a plebiscite was held in February 1948 in which the vote for India was overwhelming. Option B describes Hyderabad, where Operation Polo ran from 13 to 18 September 1948. Option C is wrong because the Radcliffe Boundary Commission drew the line between India and Pakistan in Punjab and Bengal and had no role in the princely states. Option D is wrong: the referendum of the 1950s that students sometimes recall is the vote in the Chandernagore settlement, and 1956 is the year of the States Reorganisation Act, not of any vote in Junagadh.
PEPSU, one of the unions of states formed out of princely territory, stood for which of the following?
- A.Punjab and East Provinces States Union
- B.Patiala and East Punjab States Union
- C.Princely Eastern Punjab States Union
- D.Patiala and Eastern Provinces States Union
Show answer
Correct answer: B. Patiala and East Punjab States Union
Explanation
The correct answer is B, the Patiala and East Punjab States Union. It was formed in 1948 by grouping Patiala with Kapurthala, Jind, Nabha, Faridkot, Malerkotla, Nalagarh and Kalsia, with the Maharaja of Patiala as Rajpramukh, and it became a Part B state under the Constitution of 1950. PEPSU was merged into Punjab in 1956 when the States Reorganisation Act ended the four-part classification. Options A, C and D are plausible-looking expansions built from the same words, and that is exactly how the question is set; each of them misstates either the first element, which is the state of Patiala, or the second, which is East Punjab. Remember PEPSU alongside the other unions of states created in the same years, Saurashtra from the Kathiawar states, Rajasthan from the Rajputana states, Madhya Bharat from the central Indian states and Travancore-Cochin in the south.
Under the Constitution as it came into force in 1950, the former princely states that survived as separate units were classed as which category, headed by a Rajpramukh?
- A.Part A states
- B.Part B states
- C.Part C states
- D.Part D territories
Show answer
Correct answer: B. Part B states
Explanation
The correct answer is B, Part B states. These were the former princely units and unions of states, among them Hyderabad, Mysore, Rajasthan, Saurashtra, Madhya Bharat, Travancore-Cochin, PEPSU and Jammu and Kashmir, and each was headed by a Rajpramukh rather than by a Governor. Option A, Part A states, were the former governors' provinces of British India, such as Bombay, Madras, Bihar and Uttar Pradesh, each with a Governor and an elected legislature. Option C, Part C states, were the former chief commissioners' provinces and some smaller princely areas, including Delhi, Himachal Pradesh, Vindhya Pradesh, Ajmer, Coorg, Manipur and Tripura, administered by a Chief Commissioner or Lieutenant Governor. Option D, Part D, held only the Andaman and Nicobar Islands. The whole scheme was abolished by the States Reorganisation Act, 1956, which replaced it with states and union territories.
Sikkim became a full state of the Indian Union by which constitutional amendment?
- A.35th Amendment Act, 1974
- B.36th Amendment Act, 1975
- C.42nd Amendment Act, 1976
- D.44th Amendment Act, 1978
Show answer
Correct answer: B. 36th Amendment Act, 1975
Explanation
The correct answer is B, the 36th Constitutional Amendment Act, 1975. It made Sikkim the twenty-second state of the Union after a referendum in which its people voted to end the rule of the Chogyal and to join India. Option A, the 35th Amendment of 1974, is the near miss the examiner relies on: it gave Sikkim the intermediate status of an associate state of the Union, a status that existed only for that one year. Option C, the 42nd Amendment of 1976, is the sweeping amendment of the Emergency years that added the words socialist, secular and integrity to the Preamble and created the Fundamental Duties. Option D, the 44th Amendment of 1978, reversed many of those changes and replaced internal disturbance with armed rebellion as a ground for a national emergency. Sikkim had been an Indian protectorate since 1950.
During the suzerainty of the British crown, Princely States covered what portion of the land area of the British Indian empire?
- A.One-third
- B.One-fourth
- C.One-tenth
- D.None of the above
Show answer
Correct answer: D. None of the above
Explanation
The correct answer is D, none of the above. The princely states were not a small fringe of the map. Standard accounts place their share at roughly two-fifths of the land area of the subcontinent, and some put it close to a half, with around a quarter of the population; about 565 states of every size, from Hyderabad and Kashmir down to estates of a few villages, lay between and around the British provinces. Option A, one-third, is the figure students most often guess and it understates the true extent. Option B, one-fourth, is nearer to the share of population than of area, which is where the confusion comes from. Option C, one-tenth, is far too small and would describe only a handful of the larger states. Because every fraction offered falls short of the accepted range, the paper marks the fourth option as correct. The lesson is to carry one bearing in memory: more than a third, nearer two-fifths.
Frequently Asked Questions
How many princely states were there at the time of independence?
Standard accounts put the number at around 565. They ranged from Hyderabad, larger than many European countries and with its own currency and railway, down to estates of a handful of villages. Together they covered a very large part of the subcontinent, well over a third of its land area, which is why their integration mattered so much to the shape of the new Union.
What did a ruler give up by signing the Instrument of Accession?
Only three subjects: defence, external affairs and communications. All other powers stayed with the state for the time being. Keeping the document so narrow was deliberate, because it let the States Department collect signatures quickly; the deeper merger of the states into provinces and unions of states came separately, in 1948 and 1949.
How was Hyderabad integrated into India?
The Nizam, Mir Osman Ali Khan, signed a Standstill Agreement in November 1947 and then kept postponing accession while the Razakar militia under Kasim Razvi attacked villagers. The Government of India launched a police action codenamed Operation Polo from 13 to 18 September 1948, after which the Nizam acceded and was later made Rajpramukh of the state.
Why is Sardar Patel called the Bismarck of India?
Otto von Bismarck unified the German states into one empire in the nineteenth century, and Patel, as head of the States Department from July 1947, brought around 565 princely states into the Indian Union in little more than a year. The comparison is to the combination of negotiation and firmness both men used. Patel is also called the Iron Man of India, and his birth anniversary on 31 October is observed as Rashtriya Ekta Diwas.
What were Part B states?
When the Constitution came into force on 26 January 1950, the former princely units that had survived as separate entities, such as Hyderabad, Mysore, Rajasthan, Saurashtra, Madhya Bharat, Travancore-Cochin, PEPSU and Jammu and Kashmir, were classed as Part B states. Each was headed by a Rajpramukh rather than a Governor. The States Reorganisation Act, 1956 abolished the four-part classification.
When did Goa become part of India?
Goa, together with Daman and Diu, remained under Portuguese rule for fourteen years after independence. It was taken in a military action codenamed Operation Vijay that ended on 19 December 1961, a date observed as Goa Liberation Day. Goa was a union territory until it was made a state in 1987, while Daman and Diu stayed a union territory.
