Partition and the Constituent Assembly – NDA History Notes

In the summer of 1947 CE, India experienced two of the most profound events in its recorded history, simultaneously.

One was a catastrophe. The British decision to divide British India into two independent countries, India and Pakistan, set in motion the largest forced migration in human history. Approximately 14 to 17 million people crossed the newly drawn borders between August and November 1947 CE. An estimated 200,000 to 2 million people were killed in communal violence. Entire villages were destroyed. Families were separated across borders that had not existed six months earlier. The rivers of Punjab ran with blood. The trains that carried refugees in both directions carried corpses as often as survivors. The partition of 1947 CE is remembered in the subcontinent’s collective memory as a wound that has not fully healed in three generations.

The other was a triumph. Even as partition and its violence engulfed northern India, a group of 299 men and women were meeting in New Delhi, in an elegant circular chamber in what is now the Parliament building, to write a constitution for independent India. They worked for nearly three years. They drew on constitutions from around the world, the United States, the United Kingdom, Ireland, Canada, Australia, France, and the Soviet Union, as well as India’s own Government of India Act 1935. When they finished, they had produced one of the longest and most comprehensive constitutions in the world, a document that would govern the lives of hundreds of millions of people.

These two events, the catastrophe of partition and the triumph of constitution-making, were not separate. They happened at the same time, and the people who lived through one also lived through the other. The framers of the Constitution wrote in the shadow of partition’s violence. The principles they enshrined, secularism, equality, the abolition of untouchability, fundamental rights for all citizens, were partly responses to the forces that had made partition necessary.

NDA has tested this chapter on four specific facts: the three alternative names for the Mountbatten Plan, the mechanism by which the first Prime Minister was appointed, the Sylhet referendum and its outcome, and a cross-reference to Direct Action Day from Chapter N8.

1. The Road to Partition

The Cabinet Mission Plan of 1946 CE, the last serious attempt to keep India united, had proposed a federal structure with three provincial groupings. Both the Congress and the Muslim League initially accepted it. But disagreement over the grouping clause caused the League to withdraw its acceptance. The plan collapsed.

What followed was a rapid descent into political crisis and communal violence. Direct Action Day on 16 August 1946 CE: called by the Muslim League to press for Pakistan: led to the Great Calcutta Killings in which thousands were killed. [NDA 2010-I, cross-reference from Chapter N8] The violence spread across Bengal and Bihar, demonstrating how close India had come to the edge of communal civil war.

Lord Mountbatten arrived as the last Viceroy in March 1947 CE with instructions to transfer power by June 1948 CE. He concluded quickly that a united India was impossible. The Constituent Assembly, already meeting from December 1946 CE, continued its work of constitution-making even as the political decision for partition was being made. Constitution-making and partition proceeded simultaneously.

2. The Mountbatten Plan: Three Names, One Document

The plan that determined the shape of independence is known by three different names. NDA has directly tested this. [NDA 2012-II]

Name	Why Called This
Mountbatten Plan	Named after the Viceroy who announced it
Plan Balkan	Proposed dividing India like the Balkans: into smaller national states based on community
June 3rd Plan	Announced on 3 June 1947 CE

All three names refer to the same plan. [NDA 2012-II] This is a frequently misunderstood fact. Students sometimes treat them as three separate constitutional proposals. They are not. One plan. Three names.

The plan proposed the partition of British India into two independent dominions: India and Pakistan: with power transferred on 15 August 1947 CE. Both the Congress and the Muslim League accepted the plan. The Indian Independence Act was passed by the British Parliament in July 1947 CE to give legal effect to the plan.

The three names refer to the same plan announced on 3 June 1947 CE. NOT three different proposals. NOT Plan Balkan and the Mountbatten Plan were separate. [NDA 2012-II]

3. The Indian Independence Act: July 1947 CE

The Indian Independence Act was passed by the British Parliament in July 1947 CE. It gave legal effect to the Mountbatten Plan and provided the constitutional framework for the transfer of power.

Under the Act, British India was divided into two independent dominions: India and Pakistan: from 15 August 1947 CE. Both dominions were to have their own Governor-Generals. British paramountcy over the Princely States ended. They were left free to accede to either dominion or remain independent. The office of Secretary of State for India was abolished.

4. The Partition: Human Dimensions

Sir Cyril Radcliffe and the Radcliffe Line

The boundary between India and Pakistan was drawn by Sir Cyril Radcliffe: a British lawyer who had never visited India before being given this assignment. He was given only five weeks to draw a border through Punjab and Bengal, dividing communities, villages, and families that had coexisted for centuries.

The Radcliffe Line: the partition boundary: was announced on 17 August 1947 CE: two full days after independence had already been declared. People who woke up on 15 August as citizens of an independent country did not know, for two more days, which country they were citizens of.

The Scale of Human Suffering

The partition of 1947 CE was the largest forced migration in human history. Approximately 14 to 17 million people crossed the newly drawn borders between August and November 1947 CE, Hindus and Sikhs moving eastward from what became Pakistan, and Muslims moving westward from what became India.

An estimated 200,000 to 2 million people were killed in communal violence. The range reflects the uncertainty of historical records from a period of extreme chaos. Entire communities were destroyed. The rivers of Punjab, the trains carrying refugees, and the roads between cities all became witnesses to violence of extraordinary intensity.

5. The Sylhet Referendum

One of the most specific and directly tested facts of this chapter concerns the district of Sylhet.

Sylhet was a district of Assam at the time of partition: not of Bengal, as is sometimes assumed. [NDA 2023-I] Under the terms of the partition plan, Sylhet held a referendum in 1947 CE to decide whether it would remain with India or join Pakistan. [NDA 2023-I]

Sylhet voted to join East Pakistan in the referendum. [NDA 2023-I] East Pakistan later became Bangladesh in 1971 CE.

★ IMPORTANT Three elements of the Sylhet question are tested together. [NDA 2023-I] Location: Sylhet was a district of Assam, not Bengal. Decision: it voted to join East Pakistan in a referendum. Outcome: East Pakistan later became Bangladesh. NOT Sylhet voted to remain with India. NOT Sylhet was part of Bengal. NOT it was part of any province other than Assam at the time of partition.

The Sylhet referendum was the only district to hold a referendum during the partition process. Other provinces and districts were assigned to India or Pakistan by the Boundary Commission. Sylhet alone had the specific mechanism of a public vote.

6. Integration of the Princely States

When British paramountcy ended on 15 August 1947 CE, approximately 560 Princely States were technically independent. They were not automatically part of India or Pakistan. The integration of these states into the Indian Union was one of the most remarkable achievements of the new government’s early months.

Sardar Vallabhbhai Patel, the Home Minister, led the integration. His principal instrument was the Instrument of Accession: a legal document by which each ruler agreed to join India (or Pakistan), transferring control of defence, foreign affairs, and communications to the new government while retaining internal autonomy.

The Three Difficult Cases

State	Problem	Resolution
Hyderabad	Nizam refused to accede. Large Muslim-ruled state with mostly Hindu population.	Operation Polo (Police Action): Indian military intervention: September 1948 CE: Hyderabad joined India.
Junagadh	Muslim ruler wanted to join Pakistan despite Hindu-majority population.	Plebiscite held: population voted for India.
Kashmir	Hindu ruler Maharaja Hari Singh delayed. Pakistani-backed tribal forces invaded in October 1947 CE.	Maharaja signed Instrument of Accession to India: Indian troops airlifted. The dispute continues.

7. The Constituent Assembly: Making the Indian Constitution

The Assembly’s Formation and Composition

The Constituent Assembly was established under the Cabinet Mission Plan of 1946 CE. It first met on 9 December 1946 CE: before independence and before partition.

Fact	Detail
Established under	Cabinet Mission Plan 1946 CE
First meeting	9 December 1946 CE
Temporary President	Dr Sachchidananda Sinha (oldest member)
Permanent President	Dr Rajendra Prasad (elected at second session)
Initial membership	389 members
After partition	299 members (Pakistani representatives departed)
Election method	Indirect: chosen by provincial legislative assembly members

The Constituent Assembly was not directly elected by the Indian people. Its members were chosen indirectly, elected by members of the provincial legislative assemblies. This is an important distinction.

Key Figures

Person	Role	Key Contribution
Dr B.R. Ambedkar	Chairman, Drafting Committee	Father of the Indian Constitution. Led the actual drafting of the constitutional text.
Dr Rajendra Prasad	President, Constituent Assembly	Presided over proceedings. Later became First President of India.
Jawaharlal Nehru	First Prime Minister	Moved the Objectives Resolution on 13 December 1946 CE.
K.M. Munshi	Drafting Committee member	Important drafter of the constitutional text.
Sir B.N. Rau	Constitutional Adviser	Provided technical guidance to the Assembly.

The Objectives Resolution

Jawaharlal Nehru moved the Objectives Resolution on 13 December 1946 CE: at the Constituent Assembly’s first substantive session. The Resolution declared India’s commitment to being a sovereign, democratic republic and committed to justice, liberty, equality, and fraternity for all citizens.

The Objectives Resolution became the philosophical basis of the Preamble of the Indian Constitution. But it is not the same text as the Preamble. It provided the philosophical basis. The Preamble was drafted separately.

Constitution-Making Timeline

9 December 1946 CE   →  Constituent Assembly first meets
13 December 1946 CE  →  Objectives Resolution moved by Nehru
August 1947 CE       →  Membership reduced from 389 to 299 after partition
February 1948 CE     →  Drafting Committee submits draft Constitution
26 November 1949 CE  →  Constitution ADOPTED: Constitution Day (Samvidhan Divas)
26 January 1950 CE   →  Constitution COMES INTO FORCE: Republic Day

The Constitution was adopted on 26 November 1949 CE: this is Constitution Day. It came into force on 26 January 1950 CE: this is Republic Day. These are two different dates. NOT the Constitution was adopted and came into force on the same date.

26 January was chosen as Republic Day because it was the date of the Pledge of Independence (1930 CE): when the Congress publicly declared independence as its goal.

8. Key Constitutional Features and Sources

The Indian Constitution drew from many sources, Indian and international.

Feature	Source / Inspiration
Federal structure	Government of India Act 1935 CE
Fundamental Rights	American Constitution; Karachi Resolution 1931
Directive Principles	Irish Constitution
Parliamentary democracy	British Westminster model
Emergency provisions	Government of India Act 1935 CE
Abolition of untouchability (Article 17)	Ambedkar’s lifelong campaign
Universal adult franchise	—
Reservations for SC/ST	Poona Pact 1932 (political representation tradition)

The Indian Constitution is one of the longest constitutions in the world. Its length reflects the framers’ decision to codify in constitutional text many provisions that other countries leave to ordinary legislation, partly because India’s social diversity and the recent history of partition made the framers unwilling to trust ordinary legislation to protect minority rights and social equality.

9. The First Prime Minister of India

Jawaharlal Nehru was India’s first Prime Minister. His appointment is directly tested by NDA in a specific and technical way. [NDA 2012-II]

Jawaharlal Nehru was appointed as the first Prime Minister of India by Viceroy Lord Mountbatten: on the basis of the Congress party’s recommendation. [NDA 2012-II]

He was NOT directly elected to the position by the Indian people. The Constitution did not yet exist on 15 August 1947 CE. India was governed under modified provisions of the Government of India Act 1935 at independence. The Viceroy (acting as Governor-General from 15 August onward) appointed the Prime Minister on the basis of the party that commanded confidence in the legislature.

NOT the first PM was directly elected by the people. NOT Mountbatten chose independently. The appointment was based on the Congress party’s recommendation. [NDA 2012-II]
