Chapter in a nutshell: After World War II the British decided to leave India, but the Congress–Muslim League deadlock and rising communalism made unity impossible. The Cabinet Mission (1946) failed; the Mountbatten (June 3) Plan accepted Partition; the Indian Independence Act 1947 created two dominions — India and Pakistan — on 15 August 1947, accompanied by the Radcliffe Line, mass migration and terrible communal violence.
1. Background
- WWII left Britain weak; the INA trials, RIN mutiny and mass unrest showed British rule was unsustainable.
- The Muslim League (Jinnah) demanded a separate Pakistan (two-nation theory); the Congress wanted a united India.
2. Cabinet Mission Plan (1946)
- Aimed to keep India united with a weak centre (only defence, foreign affairs, communications) and autonomous provinces in three groups (A/B/C).
- Provided for a Constituent Assembly to frame the Constitution and an Interim Government.
- Both parties first accepted, then disputes over "grouping" led to its failure.
3. Towards Partition
- Direct Action Day (16 Aug 1946): the Muslim League's call led to large-scale communal riots (Calcutta), deepening the divide.
- An Interim Government under Nehru (1946) functioned uneasily as the League obstructed it.
- Mountbatten Plan / June 3 Plan (1947): accepted the partition of India; provinces/assemblies would decide to join India or Pakistan; Bengal and Punjab to be divided.
4. The Indian Independence Act, 1947
- Passed by the British Parliament; created two independent dominions — India and Pakistan — from 15 August 1947.
- Ended British paramountcy; princely states could accede to either dominion.
- The Radcliffe Line (drawn by Sir Cyril Radcliffe) demarcated the boundary in Punjab and Bengal.
5. Consequences of Partition
- Mass migration of millions of Hindus, Sikhs and Muslims across the new border.
- Communal violence and one of history's largest refugee crises; huge loss of life.
- Division of assets, the army and territory; the Kashmir issue arose.
- Independent India became a republic in 1950 with its own Constitution.
6. Causes of Partition (why it happened)
- Communalism and the two-nation theory; separate electorates (from 1909) hardened divisions.
- British "divide and rule" policy; the League's firm demand for Pakistan; failure of unity talks.

9. Common Mistakes to Avoid
- Confusing the Cabinet Mission (unity) with the Mountbatten Plan (partition).
- Saying India became a republic in 1947 — it became a dominion in 1947, a republic in 1950.
- Forgetting separate electorates as a root cause of division.
- Mixing up Direct Action Day (1946) with the Independence Act (1947).
- Saying one person drew the border casually — it was Radcliffe, under great time pressure.

12. Cabinet Mission — the three groups
- Group A: Hindu-majority provinces (centre/south).
- Group B: Muslim-majority north-west.
- Group C: Muslim-majority east (Bengal/Assam).
13. Why Partition Became Unavoidable
- The League's firm demand for Pakistan; Jinnah's rejection of a united India.
- Mounting communal violence (after Direct Action Day) made coexistence in one state seem impossible to the leaders.
- British eagerness to leave quickly (Mountbatten advanced the date to 1947).

Solution: It was drawn hastily, splitting communities and causing migration/violence. Q8. What was the status of India immediately after 15 Aug 1947? Solution: A self-governing dominion within the Commonwealth (republic from 1950). Q9. How did separate electorates contribute to Partition?
