🎯 What you'll learn
  • Why paramountcy lapsed and what the Instrument of Accession and Standstill Agreement each did
  • The three hard cases: Junagadh, Hyderabad and Kashmir, with dates and tools
  • How unions of states, Rajpramukhs and Part B states carried the merger forward
  • Privy purses: the bargain, the 1970 Supreme Court ruling and the 26th Amendment

On 14 November 2026, the Prime Minister's Office issued a PIB release paying tribute to Pandit Jawaharlal Nehru on his birth anniversary. Nehru had spent the 1930s as the national leader who most loudly backed the people of the princely states against their rulers, and as Prime Minister in 1947 he headed the government that had to decide what to do with them. The practical work fell to his Deputy Prime Minister Sardar Vallabhbhai Patel and a civil servant, V.P. Menon. The two-man team and the legal tools they used are the subject of this article. Our Rashtriya Ekta Diwas article tells Patel's life story. Here the focus is narrower: the legal machinery, the three hard cases, and what happened to the princes. UPSC asks about it almost every year.

The Legal Gap: When Paramountcy Lapsed

By Narendra Singh · GS faculty, The Cavalier · 15 years teaching GS

British India was never a single political unit. About two-thirds of the subcontinent was ruled directly through provinces. The rest, nearly one-third of the area and about one in four Indians, lay in princely states ruled by hereditary nawabs, nizams and maharajas. They ranged from Hyderabad, as large as a European country, to estates of a few villages. The usual count is about 565, while lists of the states that fell inside India after Partition give 552. The numbers differ because small estates can be counted separately or merged.

These rulers were not British subjects. They had treaties with the Crown and accepted its paramountcy, meaning the Crown's supreme authority over defence, foreign relations and, in practice, much else. The Cabinet Mission's memorandum of 12 May 1946 said paramountcy could not be handed to a successor government. It would return to the states when the British left. The Indian Independence Act, 1947 then carried this out in Section 7: on 15 August 1947 the suzerainty of the Crown over the Indian states lapsed, and every treaty with them lapsed too. The Act did not say which dominion a state must join. Each ruler could join India, join Pakistan, or in theory stand alone. On 25 July 1947, the Viceroy, Lord Mountbatten, urged the Chamber of Princes to accede to the dominion their geography tied them to before that date. The Constituent Assembly had meanwhile reserved 93 seats for the states.

Notice what the law left unsaid. A ruler could decide for his people without asking them. The choice was left to the rulers, not the people, and CAPF 2022 tested exactly that point (see the past papers below). The Assembly is covered on our Constituent Assembly page, and the Cabinet Mission and the 1947 Act on the constitutional development page.

Trap: "paramountcy was transferred to India"

It lapsed; nothing was transferred. That is why the Instrument of Accession mattered.

Two Documents, Three Subjects

The Congress leadership feared a country of 565 mini-nations, a Balkanisation of India. Before independence, a States Department was set up under Sardar Patel, with V.P. Menon as its Secretary. (It was later renamed the Ministry of States.) Menon, who had earlier suggested to the Viceroy that states should be asked to accede, drafted the two documents that did the job. Patel's public offer, made on 5 July 1947, was deliberately modest: the Union asked the states for nothing more than accession on three subjects.

FeatureInstrument of AccessionStandstill Agreement
What it isA one-page legal document signed by the ruler; accepted by the Governor-GeneralAn interim arrangement that kept existing links going
Subjects handed to the UnionDefence, external affairs and communicationsNone: it simply continued the old arrangements (posts, telegraphs, railways, customs, currency)
Used byAlmost every state before or soon after 15 August 1947States that were still undecided, notably Hyderabad

The arithmetic worked in India's favour. By 15 August 1947, all but three major states, Hyderabad, Junagadh and Jammu & Kashmir, had acceded, along with a handful of smaller holdouts such as Jodhpur and Indore that had to be cajoled. Many rulers assumed accession on three subjects was permanent. It was only the first step.

Junagadh, Hyderabad and Kashmir

Each hard case was the reverse of a simple textbook rule. Hyderabad and Junagadh had Muslim rulers and Hindu-majority populations. Kashmir had a Hindu ruler and a Muslim-majority population. The three were handled with three different tools.

StateRuler and problemKey datesHow it was settled
Junagadh (Kathiawar)Nawab Mahabat Khan acceded to Pakistan although the state had no common border with it and most of its people were Hindu15 Aug 1947 accession announced; Nawab flees to Karachi, Oct 1947; Indian troops take over administration, 9 Nov 1947Plebiscite, 20 February 1948: overwhelming vote for India
HyderabadThe Nizam (Mir Osman Ali Khan) ruled the largest state and wanted independence; his Razakars (led by Kasim Razvi) terrorised non-Muslims while a peasant revolt spread in TelanganaStandstill Agreement, late Nov 1947 (one year); army enters 13 Sept 1948; Nizam surrenders within daysOperation Polo, officially a "police action"; Nizam later made Rajpramukh
Jammu & KashmirMaharaja Hari Singh hoped to stay independent and offered Standstill to both dominionsRaiders from Pakistan enter 22 Oct 1947; accession 26 Oct; Indian troops airlifted to Srinagar 27 OctInstrument of Accession signed on the standard three subjects

Junagadh shows the geography argument: a state ringed by Indian territory could not sensibly join a country across the sea. When the Nawab fled, his Dewan, Sir Shah Nawaz Bhutto, invited India to run the state, and a plebiscite followed. It is the one princely state of 1947-48 whose fate a popular vote decided.

Hyderabad shows the limit of patience. The Standstill bought a year, but the Nizam kept bargaining, sought support abroad and let the Razakars loose on his own people. In September 1948 the Army moved in, and the operation lasted only days. Many textbooks give November 1949, when the Nizam accepted the Indian Constitution, as the date of formal accession. So "the year Hyderabad acceded" can be 1949, while Operation Polo is 1948.

Kashmir shows accession under pressure. The Maharaja asked for help only when the raiders neared Srinagar, and India's condition was accession first. Menon flew to Jammu and obtained the signature on the standard instrument. Mountbatten accepted it with a letter saying the people's wishes should be ascertained once order was restored. The later story is in our article on seven years since the abrogation of Article 370.

From Accession to Merger: Unions, Rajpramukhs and Part B

Accession on three subjects left India with a patchwork of 500-odd internal administrations. Patel and Menon therefore moved to the second stage, merger. It took two forms. Small states were merged into neighbouring provinces. Medium-sized states were grouped into unions of states under a covenant signed by the rulers.

The first step was the Eastern States. By the end of 1947, the Orissa states and the Chhattisgarh states were merged with Orissa and the Central Provinces. The unions followed in 1948–49. In each, one senior ruler became the Rajpramukh (constitutional head, like a governor) and another the Upa-Rajpramukh. The title let the prince keep a place at the top while real power passed to an elected ministry.

UnionFormedWhat it joined
Saurashtra (United State of Kathiawar)Feb 1948Over 200 small states of Kathiawar
Madhya Bharat28 May 1948Gwalior, Indore and others of Central India
PEPSU (Patiala and East Punjab States Union)Jul 1948Patiala, Jind, Nabha, Kapurthala, Faridkot and others
RajasthanBuilt in stages; Greater Rajasthan on 30 March 1949Rajputana states
Travancore–Cochin1 July 1949Travancore and Cochin

When the Constitution came into force on 26 January 1950, its First Schedule sorted the units into four groups, and the princely states appear in two of them. Part B held nine former princely states or unions, each headed by a Rajpramukh: Hyderabad, Jammu & Kashmir, Madhya Bharat, Mysore, PEPSU, Rajasthan, Saurashtra, Travancore–Cochin and Vindhya Pradesh. Part C held smaller units run by a Chief Commissioner, including Bhopal, Himachal Pradesh, Kutch, Manipur, Tripura. Our page on the reorganisation of states shows how the 1956 Act then abolished the Part A/B/C/D scheme and the post of Rajpramukh. So in a question asking "which of these was not a Part B state?", Bhopal is the likely answer.

The late arrivals

Manipur signed its merger agreement in September 1949. Sikkim, a protectorate under its Chogyal, became an Associate State by the 35th Amendment (1974) and a State by the 36th (1975).

Privy Purses: The Bargain and Its End

The rulers did not give up their states for nothing. Under the covenants and the instruments of merger, each prince received:

  • a tax-free annual sum, the privy purse, scaled to the size and revenue of his former state (the largest, Hyderabad's, was about ₹42.9 lakh a year);
  • the right to keep personal property, palaces and, for a time, his title and privileges.

These promises were written into the Constitution itself. Article 291 made privy purses a charge on the Consolidated Fund, and Article 362 required Parliament and the legislatures to respect the guarantees. Patel defended the arrangement as the price of a peaceful, bloodless integration. By the late 1960s the argument had turned. Critics asked how a democratic republic could pay hereditary allowances, and the government decided to end them.

DateEvent
Sept 1970A constitutional amendment bill to end privy purses passes the Lok Sabha but falls just short of the two-thirds majority in the Rajya Sabha
6 Sept 1970The President issues an order withdrawing recognition of all rulers, which would end their purses
15 Dec 1970In Madhav Rao Scindia v. Union of India (the Privy Purse case), the Supreme Court strikes down the order: recognition could not be withdrawn by executive order while Articles 291 and 362 stood
Dec 1971The 26th Amendment omits Articles 291 and 362, inserts Article 363A, and amends Article 366(22): rulers cease to be recognised and privy purses are abolished
1993In Raghunathrao Ganpatrao v. Union of India, the Court upholds the 26th Amendment

Read the sequence as a lesson in method. Parliament first tried the amending power and fell just short. The government then tried an executive shortcut, and the Court said no. Only then did Parliament pass the amendment (see our amendment procedure page). Meanwhile Article 363 kept courts out of disputes arising from the old treaties and covenants.

The princes did not vanish; many entered politics, diplomacy, the Army and heritage tourism. The lesson for the exam is that integration came from three things together: pressure from the people's movements in the states (see our Gandhian national movement page), generous terms, and force where persuasion failed. Our page on schedules and special provisions lists today's First Schedule.

How UPSC Has Asked It: Past Papers Solved

Answer: (c). Provincial members were elected indirectly, and the princely states were allotted 93 seats.

Pattern

Expect a pairing question (state and method), one on the 1947 Act, and one on a post-1950 label such as Part B, Rajpramukh or privy purse. If a question says "officially acceded" or "formally", check whether the answer is the army action (1948) or the later paperwork (1949).

Frequently asked questions

What happened to paramountcy when the British left India?

Under Section 7 of the Indian Independence Act, 1947, British paramountcy over the princely states lapsed on 15 August 1947. It was not passed to India or Pakistan, so the states were free in law to join either dominion or, in theory, to stay independent.

What is the difference between the Instrument of Accession and the Standstill Agreement?

The Instrument of Accession handed defence, external affairs and communications to the Union and made the ruler part of the Indian dominion. The Standstill Agreement only continued existing links such as posts, railways and customs. Hyderabad signed a Standstill in November 1947 but no Instrument.

How were Junagadh, Hyderabad and Kashmir integrated?

Junagadh was settled by a plebiscite on 20 February 1948 after its Nawab fled to Pakistan. Hyderabad was integrated through Operation Polo, the army action of September 1948. Kashmir acceded on 26 October 1947, when Maharaja Hari Singh signed the Instrument of Accession as raiders advanced on Srinagar.

What was a Rajpramukh?

A Rajpramukh was the constitutional head of a Part B state or union of states, a post held by a former ruler. The Nizam of Hyderabad and the Maharaja of Mysore were among them. The States Reorganisation Act of 1956 abolished the post.

How and when were privy purses abolished?

Privy purses were tax-free annual payments to former rulers, guaranteed by Articles 291 and 362. In December 1970 the Supreme Court struck down a presidential order withdrawing recognition of the rulers. Parliament then passed the 26th Amendment in 1971, ending recognition and the purses.
