The Bengali Language Movement protests occur at the University of Dhaka in East Pakistan (now Bangladesh).
East Pakistan was a Pakistani province established in 1955 by the One Unit Policy, renaming the province as such from East Bengal, which nowadays is split up between India and Bangladesh. Its land borders were with India and Burma, with a coastline on the Bay of Bengal. East Pakistanis were popularly known as "Pakistani Bengalis"; to distinguish this region from India's state West Bengal (which is also known as "Indian Bengal"), East Pakistan was known as "Pakistani Bengal". In 1971, East Pakistan became the newly independent state Bangladesh.
East Pakistan was renamed from East Bengal by the One Unit scheme of Pakistani Prime Minister Mohammad Ali of Bogra. The Constitution of Pakistan of 1956 replaced the Pakistani monarchy with an Islamic republic. Bengali politician H. S. Suhrawardy served as the Prime Minister of Pakistan between 1956 and 1957 and a Bengali bureaucrat Iskander Mirza became the first President of Pakistan. The 1958 Pakistani coup d'tat brought general Ayub Khan to power. Khan replaced Mirza as president and launched a crackdown against pro-democracy leaders. Khan enacted the Constitution of Pakistan of 1962 which ended universal suffrage. By 1966, Sheikh Mujibur Rahman emerged as the preeminent opposition leader in Pakistan and launched the six-point movement for autonomy and democracy. The 1969 uprising in East Pakistan contributed to Ayub Khan's overthrow. Another general, Yahya Khan, usurped the presidency and enacted martial law. in 1970, Yahya Khan organised Pakistan's first federal general election. The Awami League emerged as the single largest party, followed by the Pakistan Peoples Party. The military junta stalled in accepting the results, leading to civil disobedience, the Bangladesh Liberation War and the 1971 Bangladesh genocide. East Pakistan seceded with the help of India.
The East Pakistan Provincial Assembly was the legislative body of the territory.
Due to the strategic importance of East Pakistan, the Pakistani union was a member of the Southeast Asia Treaty Organization. The economy of East Pakistan grew at an average of 2.6% between 1960 and 1965. The federal government invested more funds and foreign aid in West Pakistan, even though East Pakistan generated a major share of exports. However, President Ayub Khan did implement significant industrialisation in East Pakistan. The Kaptai Dam was built in 1965. The Eastern Refinery was established in Chittagong. Dacca was declared as the second capital of Pakistan and planned as the home of the national parliament. The government recruited American architect Louis Kahn to design the national assembly complex in Dacca.
The Bengali language movement (Bengali: ভাষা আন্দোলন, Bhasha Andolôn) was a political movement in former East Bengal (renamed East Pakistan in 1952) advocating the recognition of the Bengali language as an official language of the then-Dominion of Pakistan in order to allow its use in government affairs, the continuation of its use as a medium of education, its use in media, currency and stamps, and to maintain its writing in the Bengali script.
When the Dominion of Pakistan was formed after the separation of the Indian subcontinent in 1947 when the British left, it was composed of various ethnic and linguistic groups, with the geographically non-contiguous East Bengal province having a mainly Bengali population. In 1948, the Government of the Dominion of Pakistan ordained Urdu as the sole national language, sparking extensive protests among the Bengali-speaking majority of East Bengal. Facing rising sectarian tensions and mass discontent with the new law, the government outlawed public meetings and rallies. The students of the University of Dhaka and other political activists defied the law and organised a protest on 21 February 1952. The movement reached its climax when police killed student demonstrators on that day. The deaths provoked widespread civil unrest. After years of conflict, the central government relented and granted official status to the Bengali language in 1956.
The Language Movement catalysed the assertion of Bengali national identity in East Bengal and later East Pakistan, and became a forerunner to Bengali nationalist movements, including the 6-Point Movement and subsequently the Bangladesh Liberation War and the Bengali Language Implementation Act, 1987. In Bangladesh, 21 February (Ekushey February) is observed as Language Movement Day, a national holiday. The Shaheed Minar monument was constructed near Dhaka Medical College in memory of the movement and its victims. In 1999, UNESCO declared 21 February as International Mother Language Day, in tribute to the Language Movement and the ethno-linguistic rights of people around the world.
