Origins and founding

Modern Bangladesh's borders were drawn by the Radcliffe Line at the 1947 partition of Bengal: East Bengal became the eastern wing of Pakistan (renamed East Pakistan in 1956). Grievances accumulated — the 1952 language movement over Bengali, economic discrimination (East Pakistan generated ~70% of export revenue from jute and tea but received far less spending), and under-representation in the civil and military services. Sheikh Mujibur Rahman's 1966 six-point autonomy programme, the Agartala Conspiracy Case and the 1969 mass uprising preceded the Awami League's December 1970 landslide (167 of 169 East Pakistan seats). When power transfer was denied, Mujib's 7 March 1971 speech launched non-cooperation; Pakistan's Operation Searchlight (25 March 1971) began the Liberation War.

Capitals and territory

Dhaka is the capital and largest city; Chittagong the main port. The country sits on the world's largest river delta (Ganges–Brahmaputra–Meghna) with the Sundarbans, the world's largest mangrove forest; it is among the most climate-vulnerable nations.

Major rulers and key events

Independence was proclaimed on 26 March 1971 (broadcast by Major Ziaur Rahman on Mujib's behalf); the Mukti Bahini, aided by India, fought until Pakistan's surrender on 16 December 1971. The war included the Bangladesh genocide — 300,000–500,000 dead by independent estimates, 3 million by the Bangladeshi government's figure. Mujib governed until his assassination in August 1975 amid famine (1974) and one-party rule; Ziaur Rahman then dominated, founding the BNP (1978) and initiating SAARC, until his own assassination in 1981. Hussain Muhammad Ershad's military rule (1982–1990) made Islam the state religion (1988) before a mass uprising restored democracy in 1991. The "Battle of the Begums" — Khaleda Zia (BNP) versus Sheikh Hasina (Awami League) — defined politics until 2024; Hasina's long rule (2009–2024) brought rapid growth and accusations of authoritarianism, ending when the July 2024 uprising forced her flight to India (5 August 2024). An interim government under Nobel laureate Muhammad Yunus followed; the BNP returned to power in the 2026 election, with Tarique Rahman sworn in as prime minister on 17 February 2026.

Government, economy and culture

A Westminster-style unitary republic; 99% ethnically Bengali, ~91% Muslim (official), with ~170 million people (2022 census) at the world's highest rural densities. Once labelled a "basket case," Bangladesh became South Asia's second-largest economy on the strength of the world's second-largest garment industry; poverty fell from ~80% (1971) to 18.7% (2022), and its HDI growth this century was surpassed only by China's.

Decline and end (current status)

Ongoing; the 2024 revolution reset its politics, but corruption, instability and climate threats persist.

Legacy and significance

Bangladesh is the only state born of a successful 20th-century language-based nationalist secession; International Mother Language Day (21 February) commemorates the 1952 martyrs, and its development trajectory is studied worldwide.
