🇮🇳 Independence & Partition of India (1942–1947) — The Final Phase of the Freedom Struggle
ICSE Class 10HistoryJune 2026
Why this chapter matters: This chapter covers the final five years (1942–1947) of India's freedom struggle — from the Quit India Movement to the transfer of power and Partition. In ICSE, this is the concluding chapter of the Section B History unit (along with Quit India/INA). The Cabinet Mission, Mountbatten Plan, Indian Independence Act 1947, and the tragic story of Partition are frequently tested. This is also the most emotionally powerful chapter — understand the events that led to both freedom and division.
1. The Cabinet Mission (March–June 1946)
1.1 Background — Why Was the Cabinet Mission Sent?
- After WWII ended (August 1945), the Labour Party came to power in Britain (Clement Attlee became PM). The Labour government was more sympathetic to Indian demands.
- The INA Trials (1945–46) and the RIN Mutiny (February 1946) made it clear that the British could no longer rely on the Indian armed forces.
- Elections to the provincial legislatures were held in 1945–46. Congress won in 8 provinces; Muslim League won all Muslim-majority seats — proving it was the sole representative of Indian Muslims.
- The British government decided to send a high-powered mission to India to negotiate the terms of independence and the formation of a unified Indian government.
1.2 Composition of the Cabinet Mission
- Three British Cabinet members were sent to India in March 1946:
- Lord Pethick-Lawrence (Secretary of State for India) — headed the mission
- Sir Stafford Cripps (President of the Board of Trade — the same Cripps of the 1942 Mission)
- A.V. Alexander (First Lord of the Admiralty)
- They held prolonged negotiations with Congress (represented by Maulana Azad, Jawaharlal Nehru, Vallabhbhai Patel) and the Muslim League (represented by Muhammad Ali Jinnah).
1.3 The Cabinet Mission Plan (16 May 1946)
The Cabinet Mission proposed a plan for the transfer of power to a united India. Key provisions:
| Feature | Provision |
|---|---|
| 1. Rejection of Pakistan | The Mission rejected the demand for a separate Pakistan. It said the creation of Pakistan would be economically unviable and would not solve the communal problem (since a large Hindu population would remain in East Pakistan). |
| 2. Federal Union | A Union of India would be created, controlling only three subjects: Defence, Foreign Affairs, and Communications. All other subjects would be handled by the provinces. |
| 3. Three Groups of Provinces | The provinces would be divided into three groups: Group A: Hindu-majority provinces (Madras, Bombay, UP, Bihar, CP, Orissa) Group B: Muslim-majority provinces of NW India (Punjab, NWFP, Sindh, Balochistan) Group C: Muslim-majority province of NE India (Bengal, Assam) |
| 4. Constituent Assembly | A Constituent Assembly would be formed to draft India's constitution. Members would be elected by provincial legislatures (indirect election). |
| 5. Interim Government | An Interim Government would be formed immediately at the centre, representing major political parties, to run the country until the constitution was drafted. |
1.4 Reaction — Congress and Muslim League Responses
- Initially, both accepted the plan (in principle). But differences emerged over the grouping system — Congress feared the grouping would give the Muslim League dominance in Groups B and C, leading to an informal Pakistan.
- Muslim League accepted the plan because it saw the grouping as a stepping stone toward Pakistan. Jinnah said the Mission Plan contained "the seeds of Pakistan."
- Congress had reservations — especially about the grouping system. In July 1946, Nehru (newly elected Congress President) stated that Congress would enter the Constituent Assembly "completely unfettered by any agreement" — implying Congress might not follow the grouping system as intended.
- Jinnah saw this as a betrayal and withdrew the League's acceptance of the plan. On 16 August 1946, he called for Direct Action Day to achieve Pakistan.
ICSE Key Point: The Cabinet Mission Plan was the last serious attempt to keep India united. Its failure — primarily because Congress and the League could not agree on the grouping system — led directly to Partition. The Mission rejected the demand for full Pakistan at this stage, but within a year, Partition became inevitable.
2. Direct Action Day (16 August 1946) — The Great Calcutta Killings
- After the Cabinet Mission collapsed, Jinnah called for Direct Action Day (also called "Great Calcutta Killings") to show that Muslims were determined to achieve Pakistan.
- On 16 August 1946, massive communal violence broke out in Calcutta (now Kolkata). The Muslim League had declared a public holiday. The violence spiralled out of control.
- Casualties: ~4,000–5,000 people killed and ~15,000 injured in four days of rioting. Both Hindus and Muslims were killed. This was the deadliest communal violence in India's history until Partition.
- The violence spread to other parts of India — Noakhali (East Bengal), Bihar, Punjab — creating a cycle of revenge killings.
- Gandhi's response: He rushed to Noakhali (October 1946) and walked from village to village, trying to stop the violence. He stayed there for 4 months, living in Muslim homes to restore community trust.
- Impact: Direct Action Day was the point of no return. It proved that communal violence could tear the country apart. The British and Indian leaders realised that Partition was probably the only way to stop the bloodshed.
3. Interim Government (September 1946) and the Constituent Assembly
- The Interim Government was formed on 2 September 1946, with Jawaharlal Nehru as the Prime Minister (officially Vice-President of the Viceroy's Executive Council).
- The Muslim League initially refused to join but later entered the Interim Government in October 1946 (to protect Muslim interests from within).
- The Constituent Assembly met for the first time on 9 December 1946. It was boycotted by the Muslim League.
- Dr. Rajendra Prasad was elected President of the Constituent Assembly.
- The Assembly began the process of drafting India's Constitution (which was completed in November 1949, coming into effect on 26 January 1950).
4. The Mountbatten Plan (3 June 1947) — The Decision to Partition
4.1 Lord Mountbatten Arrives (March 1947)
- Lord Louis Mountbatten was appointed as the last Viceroy of India (arrived March 1947) with a clear mandate from the British government to transfer power by June 1948.
- Mountbatten quickly concluded that Partition was unavoidable — Congress and the Muslim League could not agree on a united India.
- He advanced the date for transfer of power to 15 August 1947 (from June 1948) — to avoid the breakdown of law and order.
4.2 The Mountbatten Plan / 3 June Plan (3 June 1947)
On 3 June 1947, Mountbatten announced the plan for Partition and transfer of power:
| Provision | Details |
|---|---|
| 1. Partition of India | India would be divided into two independent Dominions: India and Pakistan. |
| 2. Partition of Bengal and Punjab | These two provinces (with both Hindu and Muslim populations) would be partitioned — Muslim-majority areas would go to Pakistan; Hindu-majority areas would stay in India. |
| 3. Referendum in NWFP and Sylhet | NWFP (North-West Frontier Province) would have a referendum to choose between India and Pakistan. Sylhet (Assam) would also have a referendum to decide whether to join East Bengal (Pakistan). |
| 4. Princely States | The 565 princely states would become independent when British paramountcy lapsed. They were advised to join either India or Pakistan based on geographical contiguity and the wishes of their people. |
| 5. Boundary Commission | Two Boundary Commissions (Punjab and Bengal) would be set up under Sir Cyril Radcliffe to demarcate the borders between India and Pakistan. |
| 6. Transfer of Power | Power would be transferred to the two Dominions on 15 August 1947 — earlier than originally planned. |
4.3 Reactions to the Mountbatten Plan
- Indian National Congress: Accepted the plan (reluctantly). Gandhi was the only Congress leader who opposed Partition — he said India would be "vivisected" (cut into pieces). But Nehru, Patel, and other leaders felt Partition was the only way to end the bloodshed and achieve immediate independence. Sardar Patel was particularly instrumental in convincing Gandhi to accept Partition.
- Muslim League: Accepted the plan enthusiastically — Pakistan was finally achieved. Jinnah declared 15 August as "Pakistan Day" for Pakistan (celebrated on 14 August).
- Gandhi's anguish: Gandhi said: "I am told that I am a visionary. But I feel that the Partition will be a tragedy for both India and Pakistan." He refused to celebrate Independence Day — he was in Calcutta (Kolkata), fasting to stop the communal violence.
Most Tested Fact: The Mountbatten Plan (3 June 1947) is the most frequently asked topic from this chapter. Questions: "Describe the provisions of the Mountbatten Plan" or "Explain the 3 June Plan." Remember: (a) Partition into two Dominions, (b) Partition of Bengal & Punjab, (c) Referendum in NWFP and Sylhet, (d) Princely states to choose, (e) Radcliffe Boundary Commission, (f) Transfer of power on 15 August 1947.
5. The Indian Independence Act 1947
The Indian Independence Act was passed by the British Parliament in July 1947 and came into effect on 15 August 1947. Key provisions:
- Two Independent Dominions: India and Pakistan were created as two independent Dominions within the British Commonwealth. Each had the right to secede from the Commonwealth (become a Republic) — India did so on 26 January 1950.
- End of British Rule (Lapse of Paramountcy): British rule in India officially ended. The title of "Emperor of India" was dropped by the British monarch. The office of the Viceroy was abolished.
- Governors-General: Each Dominion would have a Governor-General as the representative of the British Crown. For India: Lord Mountbatten (until June 1948, then C. Rajagopalachari — the only Indian GG). For Pakistan: Muhammad Ali Jinnah (as Governor-General).
- Constituent Assemblies: Each Dominion would have its own Constituent Assembly to frame its constitution. Until the constitution was adopted, the Government of India Act 1935 (with modifications) would serve as the interim constitution.
- Legislative Authority: The British Parliament would no longer legislate for India. The Constituent Assembly would function as the interim Parliament (legislature) for India.
- Princely States: British paramountcy (suzerainty) over the princely states lapsed. They were free to join either India or Pakistan or remain independent (though in practice, most were integrated into India through Sardar Patel's diplomacy and, in the case of Hyderabad, police action).
- Armed Forces: The Indian armed forces were divided between India and Pakistan (a complex process supervised by a British committee under Lord Ismay).
Key Difference: The Indian Independence Act 1947 was an Act of the British Parliament that granted independence. India's Constitution (1950) is the supreme law of independent India. The Independence Act was repealed by the Indian Constitution when India became a Republic (26 Jan 1950).
6. The Partition of India — The Human Tragedy
6.1 Radcliffe Boundary Award (17 August 1947)
- Sir Cyril Radcliffe chaired the Boundary Commissions for Bengal and Punjab. He had never been to India before and was given only 5 weeks to demarcate the borders.
- The boundaries were announced on 17 August 1947 (two days after independence). The Radcliffe Line divided Bengal and Punjab.
- Problems: Radcliffe divided villages, families, farms, and even homes. The border cut through the heart of Punjab and Bengal — with no consideration for economic, cultural, or social links.
6.2 Population Transfer — The Largest in Human History
- ~15 million people were displaced — the largest mass migration in human history.
- Sikhs and Hindus from West Punjab (Pakistan) moved to East Punjab (India). Muslims from East Punjab (India) moved to West Punjab (Pakistan).
- Bengal: Hindus from East Bengal (East Pakistan, now Bangladesh) moved to West Bengal (India). Muslims from West Bengal moved to East Pakistan.
- People travelled in kolhus (refugee convoys) — on foot, bullock carts, trains — under constant threat of attack.
6.3 Communal Violence — The Massacres
- Estimates of deaths: ~5 lakh to 10 lakh (500,000 – 1,000,000) people killed in communal violence.
- ~75,000 women were abducted, raped, or forcibly converted.
- Tens of thousands of homes, villages, and neighbourhoods were destroyed. ~1,00,000 people were orphaned.
- The violence was especially brutal in Punjab — where Sikhs, Hindus, and Muslims had lived together for centuries but now turned on each other. Mutual massacres, train massacres (refugee trains were ambushed and everyone on board was killed), and systematic ethnic cleansing.
6.4 Gandhi's Role During Partition
- Gandhi was in Calcutta (Kolkata) during the Independence celebrations — fasting to stop the violence. His presence calmed the city. The "miracle of Calcutta" — Hindus and Muslims stopped fighting and greeted each other on the streets.
- In Noakhali and Bihar, Gandhi walked from village to village, pleading for peace. He stayed in Muslim homes to show trust.
- In Delhi (September 1947), when the city was overwhelmed by refugees, Gandhi launched another fast to stop the violence and to pressure the government to protect Muslims in India. He also insisted that Pakistan's share of the cash assets be paid (despite the Pakistan government using the money to fight India in Kashmir).
- Gandhi's assassination (30 January 1948): His efforts to protect Muslims and Pakistan's interests angered Hindu extremists. Nathuram Godse, a Hindu nationalist, assassinated Gandhi on 30 January 1948 at Birla House, Delhi.
6.5 Integration of Princely States
- Sardar Vallabhbhai Patel (India's first Deputy Prime Minister and Minister of Home Affairs) was responsible for integrating 565 princely states into the Indian Union.
- Through a combination of diplomacy (Instrument of Accession), persuasion, and pressure, Patel convinced almost all princely states to join India. Only three states resisted: Junagadh (annexed by India after a plebiscite), Hyderabad (annexed through Police Action in 1948), and Kashmir (acceded to India in October 1947 after Pakistani tribal invasion).
- VP Menon was the Secretary of the Ministry of States who worked closely with Patel on the integration.
ICSE 2026 Insight: Partition questions focus on (a) causes of Partition, (b) Radcliffe Line, (c) human tragedy (15 million displaced, 5–10 lakh killed). Questions on the integration of princely states highlight Sardar Patel's role. Gandhi's assassination and his role during Partition are also frequently tested.

From my 80/80 History exam (ICSE 2026): This is the final chapter of the History syllabus and it ties together everything you've studied. My strategy: (1) Cabinet Mission vs Mountbatten Plan — the comparison table above is exam gold. The key: Cabinet Mission wanted a united India, Mountbatten Plan accepted Partition. (2) Mountbatten Plan (3 June 1947) — 6 provisions: Partition into 2 Dominions, Partition of Bengal & Punjab, Referendum in NWFP & Sylhet, Princely states to choose, Radcliffe Boundary Commission, 15 Aug 1947 as transfer date. (3) Indian Independence Act 1947 — 7 provisions: 2 Dominions, end of British rule, Governors-General, Constituent Assemblies, end of British legislative authority, lapse of paramountcy, division of armed forces. (4) Partition statistics — 15 million displaced, 5-10 lakh killed, 75,000 women abducted. These numbers are impressive in an exam answer. (5) Sardar Patel's role — integration of 565 princely states (Instrument of Accession). Only 3 exceptions: Junagadh, Hyderabad, Kashmir. (6) Timeline — Quit India (1942) → WWII ends (1945) → INA Trials & RIN Mutiny (1945-46) → Cabinet Mission (1946) → Direct Action Day (Aug 1946) → Interim Govt (Sept 1946) → Mountbatten Plan (June 1947) → Independence & Partition (Aug 1947) → Gandhi assassinated (Jan 1948). This timeline connects everything. Good luck — you've now completed the entire History syllabus for ICSE Class 10!
