Independence and Partition of India

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.

7. Worked / Structured Examples (ICSE pattern)

Solution: The partition of India into India and Pakistan. Q4. What did the Indian Independence Act 1947 create? Solution: Two independent dominions — India and Pakistan — from 15 August 1947. Q5. What was the Radcliffe Line? Solution: The boundary line dividing India and Pakistan in Punjab and Bengal.

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).
Disputes over whether grouping was compulsory wrecked the plan.

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?
