  1. 1Pakistan 1947-1991: a country built from two halves
  2. 2From crisis to Bangladesh: Zia-ul-Haq, Bhutto and civil war
  3. 3Bangladesh's early years and Sri Lanka's ethnic civil war

When Pakistan was created in 1947, it was not one country but two: West Pakistan and East Pakistan.

  • Geography: the two halves were separated by over 1,600 km of Indian territory.
  • The founder: Muhammad Ali Jinnah became the first Governor-General.
  • An early loss: Jinnah died in September 1948, just a year after independence.
  • The effect: Pakistan lost its most unifying leader almost immediately, before institutions of nation building were properly established.

From the start, Pakistan faced huge problems. It inherited little of British India's industry, administration or army officer corps (most had gone to India). Millions of refugees from Partition needed housing and jobs. And the two halves of the country shared almost nothing except Islam: West Pakistan (Punjabi- and Sindhi-speaking) and East Pakistan (Bengali-speaking) had different languages, cultures, and economies.

The core problem: two nations in one state: Pakistan's founding idea — that Muslims of South Asia formed one nation — broke down once Partition actually happened. Geography, language and economic interests pulled East and West apart from day one. This tension runs through the entire 1947-1971 period and explains why Bangladesh eventually broke away.
  • Ayub Khan — army general who seized power in a military coup in 1958, ruling as president until 1969; introduced land reforms and industrial growth (the so-called "Decade of Development") but concentrated power and favoured West Pakistan
  • Basic Democracies system (1959) — Ayub Khan's indirect system where 80,000 elected local councillors chose the president and assembly, reducing genuine democratic participation
  • Economic disparity — West Pakistan received the majority of state investment and foreign aid despite East Pakistan (Bengal) generating most export earnings through jute, fuelling Bengali resentment
  • 1965 War with India — fought mainly over Kashmir; ended in stalemate (Tashkent Agreement, 1966), but East Pakistan felt undefended and exposed during the conflict

By the late 1960s, anger in East Pakistan had a clear political voice: the Awami League, led by Sheikh Mujibur Rahman, demanded regional autonomy through his "Six Points" programme (1966) — effectively home rule for East Pakistan in everything except defence and foreign affairs.

Link cause to consequence: For Paper 3, don't just describe Ayub Khan's rule — explain why it deepened East-West tension: military and economic power stayed in West Pakistan, so when Ayub fell in 1969 the crisis was already primed to explode in the East.

Ayub Khan resigned in 1969 after mass protests, handing power to another general, Yahya Khan.

  • December 1970: Yahya Khan called Pakistan's first general election on the basis of one-person-one-vote.
  • The result: decisive. The Awami League won an outright majority of seats in the national assembly.
  • Where those seats came from: entirely from East Pakistan.

West Pakistan's leaders — Yahya Khan and Zulfikar Ali Bhutto, whose Pakistan People's Party had won most West Pakistani seats — refused to let Mujibur Rahman become prime minister of the whole country. Talks collapsed. In March 1971, the Pakistani army launched Operation Searchlight, a brutal crackdown on Bengali nationalists in Dhaka.

1971: war and the birth of Bangladesh: The crackdown triggered a civil war. Bengali resistance fighters (the Mukti Bahini) fought the Pakistani army through 1971, with millions of refugees fleeing into India. In December 1971, India intervened militarily against Pakistan; within two weeks the Pakistani army surrendered in Dhaka. East Pakistan became the independent state of Bangladesh (see micro 20.16.1 for the India-Pakistan war angle in full).
1

Defeat and reckoning (1971-1972)

Pakistan lost half its population and territory in the 1971 war. Yahya Khan resigned in disgrace.

2

Bhutto takes power (1971-1977)

Zulfikar Ali Bhutto became president then prime minister of the now-smaller Pakistan, introducing a new constitution (1973) and nationalising major industries.

3

Bhutto overthrown (1977)

Accused of rigging elections, Bhutto was removed in a military coup by General Zia-ul-Haq, then executed in 1979.

4

Zia-ul-Haq's rule (1977-1988)

Zia imposed martial law and a programme of Islamisation (sharia-based laws, Hudood Ordinances); died in a plane crash in 1988.

Defeat shrinks the state, Bhutto rebuilds it, a coup removes him, and Zia remakes it in a stricter Islamic mould.

Zia-ul-Haq's death in 1988 opened the way for civilian rule. Benazir Bhutto (Zulfikar's daughter) became prime minister twice (1988-1990 and 1993-1996), the first woman to lead a Muslim-majority country — though both her governments were dismissed early on corruption charges, showing how fragile Pakistani democracy still was. In 1991, following years of debate about the balance between Islamic and secular law, Pakistan held a constitutional referendum confirming Islamic provisions within the legal system, closing our period.

Nation-building failures, in one line: Pakistan 1947-1991 struggled because power kept swinging between elected civilians and the military, and because West Pakistan's dominance over the East made the state's founding idea — Muslim unity — collapse into division and, ultimately, partition.

Bangladesh: nation-building after 1971

Bangladesh began independence in 1971 as one of the poorest countries in the world, devastated by war and a series of floods and famines. Sheikh Mujibur Rahman became its first prime minister, but his government struggled with corruption and food shortages. In 1975, Mujib was assassinated in a military coup, beginning a long period of instability with alternating military and civilian rule through the 1970s and 1980s — a pattern of fragile democracy echoing Pakistan's own struggles.

  • Famine of 1974 — poor harvests and distribution failures killed tens of thousands, badly damaging confidence in the new government
  • Military rule — General Ziaur Rahman took power after 1975 and ran the country until his own assassination in 1981, followed by further military governments into the 1980s
  • Slow economic development — Bangladesh remained heavily dependent on foreign aid and textile/jute exports, with nation-building complicated by overpopulation and vulnerability to cyclones and flooding

Ceylon/Sri Lanka: from independence to civil war

Ceylon (renamed Sri Lanka in 1972) gained independence peacefully from Britain in 1948, without partition or war. But it held a deep ethnic divide: the majority Sinhalese (mostly Buddhist) and the minority Tamils (mostly Hindu, many descended from labourers brought from India by the British).

The Sinhala Only Act (1956): Sinhalese-dominated governments passed laws favouring the majority, most notably making Sinhala the sole official language in 1956. This shut Tamils out of many government jobs and university places, and became the single most important cause of rising Sinhalese-Tamil tension.

Sirimavo Bandaranaike became prime minister in 1960 — the world's first female head of government — after her husband, S.W.R.D. Bandaranaike (who had introduced the Sinhala Only Act), was assassinated in 1959. She continued nationalist, Sinhalese-favouring policies, deepening Tamil grievances over the following decades.

YearEventSignificance
1956Sinhala Only ActTamils excluded from state jobs/education; radicalises Tamil politics
1971JVP uprisingSinhalese youth-led Marxist insurrection, brutally suppressed; shows wider social unrest, not only ethnic
1972Ceylon renamed Sri LankaNew constitution further entrenches Buddhism and Sinhala as state language/religion
1976Tamil Eelam declared as a goalTamil United Liberation Front formally demands a separate Tamil state
1983"Black July" riotsAnti-Tamil pogrom kills thousands; widely seen as the start of full civil war
1971 JVP uprising — don't confuse it with the ethnic conflict: The 1971 uprising was a Sinhalese Marxist youth rebellion (JVP) against poverty and unemployment, crushed by Bandaranaike's government — a separate crisis from the Sinhalese-Tamil ethnic conflict, even though both reflect a state struggling to hold together different groups.
