HC15 — Partition, Integration & Post-Independence India

📚 HC15 · Freedom Struggle – VI  ·  Chapter 3 of 3 CDS Level ★ High Priority
📌 CDS Focus: Mountbatten Plan, Radcliffe Line, integration of princely states (especially Junagadh, Hyderabad, Kashmir), Constituent Assembly, and key constitutional amendments are high-frequency CDS topics. Post-independence wars with Pakistan and China, Panchsheel, NAM, and key acts like Dowry Prohibition and Hindu Code Bill are tested across years. The 42nd and 44th Amendments are among the most tested amendments.
PART A — PARTITION OF INDIA (1947)

1. Partition & Independence

1.1 Mountbatten Plan — June 1947 PYQ

Mountbatten Plan (3 June Plan): Lord Mountbatten (last Viceroy) announced the plan on 3 June 1947. Key provisions: (1) British India partitioned into India and Pakistan. (2) Provinces could vote on which country to join. (3) Bengal and Punjab to be partitioned. (4) Princely states given choice — join India, Pakistan, or remain independent. (5) Independence on 15 August 1947. The Indian Independence Act 1947 was passed by British Parliament on 18 July 1947.

📌 Key Facts

  • Radcliffe Line — boundary drawn by Sir Cyril Radcliffe (never visited India); divided Punjab and Bengal
  • Radcliffe had only 5 weeks to draw the line — completed in haste
  • Boundary announced 17 August 1947 — two days AFTER Independence
  • India became independent: 15 August 1947
  • Pakistan became independent: 14 August 1947
  • Last Viceroy: Lord Mountbatten; became first GG of India

⚠ Partition Traps

  • Mountbatten became GG of India after Independence
  • Jinnah became GG of Pakistan
  • Radcliffe Line announced 17 August — NOT 15 August
  • East Pakistan became Bangladesh in 1971
  • Nehru delivered "Tryst with Destiny" speech at midnight 14–15 Aug 1947
  • C. Rajagopalachari (Rajaji) = first Indian GG (after Mountbatten left)
PART B — INTEGRATION OF PRINCELY STATES

2. Integration of Princely States — Sardar Patel

2.1 Role of Sardar Patel High Priority PYQ

Sardar Vallabhbhai Patel (Deputy PM and Home Minister) is credited as the "Iron Man of India" for integrating 562 princely states into the Indian Union. Most states signed the Instrument of Accession (IoA) peacefully. Three states posed challenges: Junagadh, Hyderabad, and Kashmir.
⚔️

Junagadh

Gujarat Coast
  • Muslim Nawab (Mahabat Khan) wanted to join Pakistan despite Hindu-majority population
  • India refused to accept; held a referendum/plebiscite
  • Population voted overwhelmingly to join India (1948)
  • Integrated through political pressure + plebiscite
⚔️

Hyderabad

Largest Princely State
  • Nizam Mir Osman Ali Khan wanted independence; refused to sign IoA
  • Operation Polo (Police Action) — September 1948 — Indian Army moved in
  • Hyderabad integrated within 5 days
  • Integrated through military action — "Police Action" by Sardar Patel
⚔️

Kashmir

Most Complex
  • Hindu King (Maharaja Hari Singh) with Muslim-majority population
  • Pakistan-backed tribal raiders invaded Oct 1947
  • Hari Singh signed IoA with India (26 Oct 1947) — Article 370 given (special status)
  • India referred matter to UN; ceasefire Jan 1949
  • Integrated through IoA + military intervention
⚠ Integration Traps: (1) Hyderabad was integrated through military action (Operation Polo) — NOT plebiscite. (2) Junagadh was integrated through plebiscite — NOT military action. (3) Kashmir's IoA was signed on 26 October 1947 — after tribal invasion began (not before). (4) V.P. Menon was Patel's key aide in integration — Secretary of States Ministry. (5) Article 370 gave Kashmir special status — abrogated in 2019.

📄 Topic-Wise PYQs & Tricky Questions

Q1. Hyderabad was integrated into India through: CDS PYQ
(a) Plebiscite(b) Instrument of Accession (c) Military action (Operation Polo)(d) Diplomatic pressure alone
✔ Answer: (c) Military action (Operation Polo)
Hyderabad was integrated through Operation Polo (Police Action) in September 1948 when Indian Army entered Hyderabad after Nizam Mir Osman Ali Khan refused to sign the Instrument of Accession. The operation lasted 5 days. It was called a "police action" because Hyderabad was technically a domestic matter. Sardar Patel ordered the action. Plebiscite was used for Junagadh.
Q2. The Radcliffe Line was announced: Tricky
(a) 15 August 1947(b) 14 August 1947 (c) 17 August 1947(d) 3 June 1947
✔ Answer: (c) 17 August 1947
The Radcliffe Line — the boundary dividing British India into India and Pakistan — was announced on 17 August 1947, two days after India gained independence. Sir Cyril Radcliffe completed the boundary in just 5 weeks. The deliberate delay in announcing the line was to prevent pre-partition communal rioting from being guided by the boundary. The result was still massive violence once the line was revealed.
Q3. Who was the Chairman of the Drafting Committee of the Indian Constitution? CDS PYQ
(a) Jawaharlal Nehru(b) Rajendra Prasad (c) Sardar Patel(d) B.R. Ambedkar
✔ Answer: (d) B.R. Ambedkar
Dr. B.R. Ambedkar was the Chairman of the Drafting Committee of the Constituent Assembly. He is called the "Father of the Indian Constitution." Dr. Rajendra Prasad was the President of the Constituent Assembly (not the Drafting Committee). The Constitution was adopted on 26 November 1949 and enforced on 26 January 1950.
Q4. Which amendment added 'Socialist', 'Secular', and 'Integrity' to the Preamble? CDS PYQ
(a) 24th Amendment(b) 42nd Amendment (c) 44th Amendment(d) 52nd Amendment
✔ Answer: (b) 42nd Amendment
The 42nd Constitutional Amendment (1976), enacted during the Emergency period under PM Indira Gandhi, added the words "Socialist," "Secular," and "Integrity" to the Preamble. It is called the "Mini Constitution" for the sweeping changes it made. The 44th Amendment (1978) reversed many of the 42nd Amendment's provisions that were seen as authoritarian.
Q5. The Tashkent Agreement (1966) was signed after which war? CDS PYQ
(a) 1962 China War(b) 1947–48 Kashmir War (c) 1965 Indo-Pak War(d) 1971 Bangladesh War
✔ Answer: (c) 1965 Indo-Pak War
The Tashkent Agreement was signed on 10 January 1966 after the 1965 Indo-Pak War, mediated by Soviet Premier Alexei Kosygin in Tashkent (then USSR, now Uzbekistan). India's PM Lal Bahadur Shastri signed for India; Ayub Khan for Pakistan. Tragically, Shastri died of a heart attack in Tashkent the next day (11 January 1966). The 1971 war ended with the Simla Agreement (1972).
Q6. Panchsheel Agreement was signed between India and China in: CDS PYQ
(a) 1950(b) 1954 (c) 1955(d) 1961
✔ Answer: (b) 1954
The Panchsheel Agreement (Five Principles of Peaceful Coexistence) was signed between India (PM Nehru) and China (PM Zhou Enlai) on 29 April 1954, as part of the agreement on trade relations with Tibet. The 1955 Bandung Conference further popularised these principles globally. The 1961 date refers to the first NAM summit in Belgrade.
Q7. The voting age was reduced from 21 to 18 by which amendment? Tricky
(a) 52nd Amendment(b) 61st Amendment (c) 73rd Amendment(d) 44th Amendment
✔ Answer: (b) 61st Amendment
The 61st Constitutional Amendment (1988) lowered the voting age from 21 to 18 years. This was done under PM Rajiv Gandhi to include youth in the democratic process. The 52nd Amendment (1985) introduced the Anti-Defection Law. The 73rd Amendment (1992) gave constitutional status to Panchayati Raj institutions. The 44th Amendment (1978) reversed Emergency-era changes.
Q8. The first linguistic state in India was: CDS PYQ
(a) Karnataka(b) Andhra Pradesh (c) Tamil Nadu(d) Maharashtra
✔ Answer: (b) Andhra Pradesh
Andhra Pradesh was the first state created on linguistic lines — carved out of the Madras State in 1953, after Telugu-speaking leader Potti Sriramalu fasted unto death demanding a separate state for Telugu speakers. His death triggered mass protests and forced the government to create Andhra State. The States Reorganisation Act of 1956 then reorganised all states on linguistic lines.
