I. Yahya Khan Takes Over

  • 25 March 1969: Ayub Khan abdicated and handed power to Gen. Agha Muhammad Yahya Khan (Army C-in-C).
  • Yahya imposed martial law, abrogated the 1962 Constitution and became CMLA (and later President).
  • He announced:
    • free and fair elections on adult franchise
    • that the elected assembly would frame a new constitution.
  • With no constitution in force, he issued the Legal Framework Order (LFO) to fill the legal vacuum.

Nature

  • A document of 27 articles that gave legal cover for the elections. It dealt with:
    • the number of seats in the NA and PAs
    • nomination papers
    • qualifications and disqualifications of candidates
    • the Election Commission.
  • It also laid down the principles of the future constitution, which the new assembly had to follow.
  • 🔥 Very important for all competitive exams.

A. National Assembly: 313 seats

  • 300 general seats plus 13 reserved for women.
  • East Pakistan: 169 (162 general + 7 women).
  • West Pakistan: 144 (138 general + 6 women).
  • This was the first time parity was abandoned. Seats were given by population.

Punjab186 (180 + 6)

C. Election schedule

  • NA elections were set for 5 October 1970, and PA elections before 22 October 1970.
  • Floods in East Pakistan caused a postponement. The NA polls were held on 7 December 1970, and the PA polls about 10 days later.
  • At the time, national and provincial polls were held on different days.

D. Principles of the future constitution

  1. Pakistan to be a Federal Republic named the Islamic Republic of Pakistan.
  2. Head of State to be a Muslim, and the Islamic ideology preserved.
  3. Democracy: free, periodic elections to the federal and provincial legislatures on adult franchise (on population).
  4. Independent judiciary and fundamental rights for citizens.
  5. Maximum provincial autonomy, while the centre also remains strong (enough power to discharge its federal duties).
  6. Citizens' participation in state affairs, and removal of economic disparities between regions within a set period.
  7. Muslims to be able to live according to Islam; minorities free to follow their faith, with full citizenship rights.

E. Status of the assemblies

  • The National Assembly would be:
    • the only legislature, if the federal legislature had one house
    • or the lower house, if it had two houses.
    • The choice of unicameral or bicameral was left to the new assembly.
  • Both the NA and the PAs would serve a full term.

F. The 120-day clause (controversial)

  • The NA had to frame the constitution bill within 120 days of its first meeting. Otherwise it would stand dissolved.
  • The President's authentication (assent) was required. If he refused, the Assembly would be taken to have failed, and would be dissolved.
  • ⚠️ This gave Yahya a veto over the constitution. It was a very tough condition.

G. Other provisions

  • The President would arrange the first meeting of the NA after the elections.
  • A code of conduct was set for parties. Any party that violated it could be barred from the elections, like a sword hanging over parties.

III. Dissolution of One Unit (1 July 1970)

  • Yahya dissolved One Unit on 1 July 1970.
  • West Pakistan was divided again into four provinces: Punjab, Sindh, NWFP and Balochistan.
  • Each got its own provincial assembly, and seats in the NA under the LFO.

IV. General Elections, 7 December 1970

  • The first direct general elections since independence, on adult franchise. Earlier NA elections had been indirect.
  • Voting was held for 300 general seats: 162 East and 138 West. The 13 women's seats were elected indirectly by the assembly.
  • Turnout: about 58–63%. It is widely regarded as Pakistan's fairest election.

Main contestants

  • Awami League (AL), led by Sheikh Mujibur Rahman:
    • a Bengali nationalist party
    • the only major party in East Pakistan
    • campaigned on the Six Points.
  • Pakistan Peoples Party (PPP), led by Z.A. Bhutto:
    • a left-leaning, socialist party based in West Pakistan
    • slogan: "Roti, Kapra aur Makan" (bread, clothing and shelter).
    • It faced tough competition from conservative Muslim League factions (especially PML-Qayyum), and from Islamist parties (Jamaat-e-Islami, JUI, JUP).
  • The government favoured pro-Islamic parties, as they were committed to a strong federation.
  • The result looked like a two-party contest: Bengali nationalism (AL) vs socialism (PPP).

NAP (Wali)617
Jamaat-e-Islami4—4
PML (Convention)2—2
Pakistan Democratic Party1—1
Independents16—16
  • The Awami League won a clear simple majority (167 of 313), enough to form the government alone.
  • Vote share:
    • AL about 39% (~1.29 crore votes)
    • PPP about 18.6% (~61 lakh)
    • JI about 6%
    • Council ML about 6%
    • PML-Q about 4.5%
    • JUI and JUP about 4% each.
    • The religious parties together got under 10%.

Analysis: a polarised verdict

  • The PPP won no seat in East Pakistan, and the AL won no seat in West Pakistan.
  • The East–West tension built up over the previous 8–10 years showed openly: each wing voted only for its own regional party.
  • Old parties (Muslim League factions) were rejected. Religious parties made no breakthrough.
  • There was no truly national party, a warning sign for national unity.

V. Provincial Assembly Results (December 1970)

Balochistan (20 general)NAP (Wali)8, the largest party (split mandate). Qayyum ML 3, JUI 2, others; 5 independents
  • Pattern:
    • AL in the East
    • PPP in Punjab and Sindh
    • NAP (with JUI) in NWFP and Balochistan.

VI. Post-Election Crisis (December 1970 – March 1971)

  • The NA was not convened promptly, as the LFO required.
    • Yahya and Bhutto (PPP) did not want an East Pakistani party heading the federal government on the basis of the Six Points.
  • Mujib and the AL demanded a swift transfer of power under the Six Points, and refused to dilute them.
  • Efforts at compromise:
    • Mujib was pressed to soften the Six Points and find a middle way.
    • Nurul Amin, a veteran Bengali politician, was later made PM (December 1971) to bridge the PPP and AL.
  • NA session:
    • Yahya summoned the NA to meet in Dhaka on 3 March 1971.
    • Bhutto opposed it, saying conditions were not right and the PPP would boycott it.
    • Under this pressure, Yahya postponed the session (1 March 1971; the lecture says 28 Feb).
  • Reaction in East Pakistan:
    • Deep disillusionment among AL supporters.
    • Mujib called a general strike and a non-cooperation movement, which paralysed the government. His famous 7 March speech came in this period.
  • Ethnic violence:
    • Militants targeted the Bihari (Urdu-speaking) community, which supported West Pakistan.
    • In early March 1971, 300+ Biharis were reported killed by Bengali mobs in Chittagong.
  • Dhaka talks (March 1971):
    • Yahya flew to Dhaka to meet Mujib, and Bhutto joined later.
    • The talks failed and the deadlock continued. Mujib held firm on the Six Points, while Yahya and Bhutto wanted a compromise.

VII. Operation Searchlight & the Civil War (March–November 1971)

  • 25 March 1971: the government launched a military operation in East Pakistan, Operation Searchlight.
    • Stated aim: to crush the Bengali separatist movement, stop the violence against Biharis, and restore law and order.
    • Plan: take control of the major cities by 26 March.
    • Mujib was arrested and flown to West Pakistan.
  • The main phase ended by mid-May 1971, when the last major Bengali-held town fell.
  • Mukti Bahini:
    • Many insurgents and civilians fled to India as refugees.
    • Indian intelligence (RAW) and the Indian army trained and armed them in guerrilla warfare, and sent them back as the Mukti Bahini.
  • The Bangladesh Liberation War followed: Indian-backed Mukti Bahini guerrillas against the Pakistan Army.
  • Loyalists, mostly from the persecuted Bihari minority, formed militias (Razakars, Al-Badr, Al-Shams) to support Pakistani troops.
  • ⚠️ Balanced note for exams: the military operation and the civil war caused very heavy civilian casualties, and some 10 million refugees fled to India. Human-rights abuses were reported on all sides. Figures remain disputed, and Pakistan's Hamoodur Rahman Commission later examined the conduct of the war.

VIII. The 1971 War & Fall of Dhaka

  • 3 December 1971, Operation Chengiz Khan: the Pakistan Air Force launched pre-emptive strikes on Indian air bases (around six) in the west.
    • They were described as the bases supplying the Mukti Bahini.
    • This marked the formal start of the Indo–Pakistan War of 1971.
  • Direct Indian military intervention followed. Indian forces advanced into East Pakistan in support of the Mukti Bahini and the AL.
  • 16 December 1971: Pakistan's Eastern Command surrendered unconditionally in Dhaka.
    • Lt Gen A.A.K. Niazi surrendered to Lt Gen Jagjit Singh Aurora.
    • East Pakistan was dismembered, and the independent state of Bangladesh emerged.
  • About 93,000 prisoners of war were taken by India, including roughly:
    • 55,000 army
    • 16,000 paramilitary
    • 5,000 police
    • 1,000 navy
    • 800 air force
    • plus civilians and collaborators.
  • 16 December 1971 is regarded as the blackest day in Pakistan's history.
  • Yahya's rule ended with the dismemberment of Pakistan. He resigned on 20 December 1971 and handed power to Z.A. Bhutto, who became President and the first civilian CMLA.

✍️ Model Answer Outlines

Q1. Discuss the salient features of Yahya Khan's Legal Framework Order 1970.

  1. Background: Ayub's fall, martial law, and the need for a legal basis for elections.
  2. Features:
    • 27 articles
    • a 313-seat NA on population (parity ended)
    • provincial seats
    • the election schedule
    • principles for the new constitution (Islamic republic, federal, adult franchise, independent judiciary, fundamental rights, maximum autonomy with a strong centre, removal of disparities)
    • the 120-day deadline and presidential authentication
    • the code of conduct for parties.
  3. Critique: it gave the President a veto over the constitution; "maximum autonomy with a strong centre" was vague.
  4. Conclusion: the basis for the 1970 elections, but its ambiguities fed the 1971 crisis.

Q2. Analyse the results of the 1970 elections and their consequences.

  • The first direct election; fair; about 58% turnout.
  • AL 167 (East sweep, Six Points); PPP 85 (West, Roti Kapra Makan).

    • political and economic disparity
    • the language issue
    • denial of power after the 1970 election
