Partition and the integration of princely states

In 1947, India faced two enormous tasks at once — coping with the violence and displacement of Partition, and bringing more than five hundred princely states into the Union. How it was done, and what it cost.

On 15 August 1947, India became independent, and also divided. The Partition created two countries, set off one of the largest migrations in human history, and left deep scars. At the same moment, the new Indian state had to bring together more than five hundred princely states that had been under British paramountcy but not British India.

The consolidation of India after 1947 is part of the GS I syllabus ("post-independence consolidation and reorganisation within the country"), and questions on Patel, the princely states and Partition's social consequences appear regularly.

The road to Partition

  • The Cabinet Mission Plan (1946) proposed a loose federation with groupings of provinces; it broke down amid disagreement between the Congress and the Muslim League.
  • The Muslim League called for Direct Action Day (16 August 1946), followed by severe communal violence in Calcutta and elsewhere.
  • Lord Mountbatten, the last Viceroy, announced the plan for partition on 3 June 1947 (the Mountbatten Plan).
  • The Indian Independence Act, 1947, passed by the British Parliament in July, created two dominions, India and Pakistan, from 15 August 1947.
  • Sir Cyril Radcliffe chaired the Boundary Commissions for Punjab and Bengal; the boundary award — the Radcliffe Line — was made public only after independence.

The human cost

Partition was accompanied by massacres, abductions and sexual violence on all sides, particularly in Punjab. Estimates of the number displaced run into the millions — often cited at well over ten million — and estimates of deaths vary widely, from a few hundred thousand to around a million or more.

The new government faced the immediate tasks of relief and rehabilitation: refugee camps, land allotment (especially in Punjab), housing colonies around Delhi and other cities, and the restoration of order. Rehabilitation in the east, where migration continued for years, proved slower and more difficult.

The princely states

About 565 princely states (the number varies slightly by source) covered roughly two-fifths of the subcontinent's territory. Some, like Hyderabad and Kashmir, were larger than many European countries; others were tiny estates.

With the end of British paramountcy, the Indian Independence Act left them technically free to accede to India or Pakistan — or, in theory, to remain independent. A patchwork of independent states would have made the new country impossible to govern.

Patel, Menon and the Instrument of Accession

The States Department, headed by Sardar Vallabhbhai Patel with V.P. Menon as its secretary, handled integration.

The method combined persuasion and pressure:

  1. The Instrument of Accession — rulers were asked to accede to India on only three subjects: defence, external affairs and communications. This limited demand made accession easier to accept.
  2. Standstill Agreements kept existing arrangements in place during the transition.
  3. Appeals to patriotism and to the rulers' own interests, alongside warnings about popular movements within their states and the risks of isolation.

By 15 August 1947, almost all states within India's borders had acceded.

The difficult cases

StateSituationOutcome
JunagadhMuslim ruler, Hindu-majority population, surrounded by Indian territory; the ruler acceded to PakistanPopular protest; Indian administration took over; a plebiscite in February 1948 overwhelmingly favoured India
HyderabadThe Nizam sought independence; the Razakars, a militia, carried out violence; the Telangana peasant struggle was also under wayAfter negotiations failed, Indian troops moved in during September 1948 (Operation Polo); Hyderabad joined India
Jammu and KashmirHindu ruler, Muslim-majority population; Maharaja Hari Singh delayed a decisionAfter an invasion by tribesmen backed by Pakistan in October 1947, the Maharaja signed the Instrument of Accession; Indian troops were sent; the matter went to the UN

Other states, such as Travancore, Bhopal and Jodhpur, initially hesitated before acceding.

From accession to integration

Accession on three subjects was only the first step. Over the next years:

  • Many small states were merged with neighbouring provinces (for example, the Orissa and Chhattisgarh states).
  • Others were grouped into unions such as Saurashtra, Madhya Bharat, Rajasthan, PEPSU and Travancore-Cochin.
  • Rulers signed agreements accepting the full authority of the Indian Constitution, in return for privy purses (annual payments) and certain privileges.
  • The Constitution classified the new units into Part A, B, C and D states; this classification was replaced after the States Reorganisation Act, 1956.

The privy purses were abolished by the 26th Amendment (1971).

Why integration succeeded

  • Patel's firmness and pragmatism, and Menon's administrative skill.
  • The limited initial demand of the Instrument of Accession.
  • Popular movements within the states — the States' People's Conference had long demanded democratic rights.
  • The rulers' realistic assessment that there was no viable alternative.
  • Generous terms — privy purses and privileges — that eased the transition.

Practice questions

  1. Prelims-type: Which three subjects were covered by the Instrument of Accession? Which amendment abolished privy purses?
  2. Mains-type (150 words): How did Junagadh, Hyderabad and Kashmir present different challenges to integration?
  3. Mains-type (250 words): "The integration of princely states was one of the greatest achievements of the early Indian state." Discuss.
