East Bengal in the context of "Muhammad Ali Jinnah"

Bangladesh, officially the People's Republic of Bangladesh, is a country in South Asia. It is the eighth-most populous country in the world and among the most densely populated with a population of over 171 million within an area of 148,460 square kilometres (57,320 sq mi). Bangladesh shares land borders with India to the north, west, and east, and Myanmar to the southeast. It has a coastline along the Bay of Bengal to its south and is separated from Bhutan and Nepal by the Siliguri Corridor, and from China by the Indian state of Sikkim to its north. Dhaka, the capital and largest city, is the nation's political, financial, and cultural centre. Chittagong is the second-largest city and the busiest port of the country.

The territory of modern Bangladesh was a stronghold of many Hindu and Buddhist dynasties in ancient history. Following the Muslim conquest in 1204, the region saw Sultanate and Mughal rule. During the Mughal period, particularly under the Bengal Subah, the region emerged as one of the most prosperous and commercially active parts of the world, known for its thriving textile industry and agricultural productivity. The Battle of Plassey in 1757 marked the beginning of British colonial rule for the following two centuries. In the aftermath of the Partition of India in 1947, East Bengal became the eastern and most populous wing of the newly formed Dominion of Pakistan and was later renamed to East Pakistan.

The University of Dhaka (Bengali: ঢাকা বিশ্ববিদ্যালয়), also known as Dhaka University (DU), is a public research university located in Dhaka, Bangladesh. Established in 1921, it is the oldest active university in the country.

The University of Dhaka was founded in 1921 under the Dacca University Act 1920 of the Indian Legislative Council. The establishment of the university in Dhaka was initiated with 600 acres of land requisitioned by the British government in 1905 after a new province of East Bengal and Assam was formed with Dhaka as its capital. Part of the land requisitioned belonged to the estate of Nawab Bahadur Sir Khwaja Salimullah. It is modeled after British universities. Currently it is the largest public research university in Bangladesh, with a student body of 46,150 and a faculty of 1,992.

The Brahmaputra is a trans-boundary river which flows through Southwestern China, Northeastern India, and Bangladesh. It is known as the Brahmaputra or Luit in Assamese, Yarlung Tsangpo in Tibetan, the Siang/Dihang River in Arunachali, and Jamuna River in East Bengal. By itself, it is the 9th largest river in the world by discharge, and the 15th longest.

It originates in the Manasarovar Lake region, near Mount Kailash, on the northern side of the Himalayas in Burang County of Tibet where it is known as the Yarlung Tsangpo River. The Brahmaputra flows along southern Tibet to break through the Himalayas in great gorges (including the Yarlung Tsangpo Grand Canyon) and into Arunachal Pradesh. It enters India near the village of Gelling in Arunachal Pradesh and flows southwest through the Assam Valley as the Brahmaputra and south through Bangladesh as the Jamuna (not to be confused with the Yamuna of India). In the vast Ganges Delta, it merges with the Ganges, popularly known as the Padma in Bangladesh, and becomes the Meghna and ultimately empties into the Bay of Bengal.

East Pakistan was the eastern province of Pakistan between 1956 and 1971, restructured and renamed from the province of East Bengal and covering the territory of the modern country of Bangladesh. Its land borders were with India and Burma, with a coastline on the Bay of Bengal. To distinguish this region from India's state West Bengal (which is also known as "Indian Bengal"), East Pakistan was known as "Pakistani Bengal". East Pakistanis were popularly known as "Pakistani Bengalis". In 1971, East Pakistan became the newly independent state Bangladesh, which means "country of Bengal" or "country of Bengalis" or "land of Bengalis" in the Bengali language. In standard meaning, "desh" refers to a country, but in Bangla local expressions, "desh" also means one's village or countryside, hometown, ancestral heritage, homeland, and they do not have to be a politically formed sovereign country.

East Pakistan was formed with West Pakistan at the reorganization of One Unit Scheme orchestrated by the 3rd prime minister of Pakistan, Mohammad Ali. 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'état 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, 1971 Bangladesh genocide and persecution of Biharis.

Bihari (listen) is a demonym given to the inhabitants of the Indian state of Bihar. Bihari people can be separated into three main Indo-Aryan ethnolinguistic groups: Bhojpuris, Maithils and Magahis. They are also further divided into a variety of hereditary caste groups.In Bihar today, the Bihari identity is seen as secondary to caste/clan, linguistic and religious identity but nonetheless is a subset of the larger Indian identity. Biharis can be found throughout India, and in the neighbouring countries of Nepal, Pakistan and Bangladesh. During the Partition of India in 1947, many Bihari Muslims migrated to East Bengal (renamed to East Pakistan; later became Bangladesh). Bihari people are also well represented in the Muhajir people of Pakistan (formerly West Pakistan) because of Partition.

The Bengali language movement was a political movement in East Bengal (modern-day Bangladesh) in 1952, advocating the recognition of the Bengali language as a co-lingua franca of the then-Dominion of Pakistan 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 alphabet and 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 ethnic Bengali population. In 1948, the Government of the Dominion of Pakistan ordained as part of Islamization of East Pakistan or East Bengal that Urdu will be the sole federal language, alternately Bengali writing in the Perso-Arabic script or Roman script (Romanisation of Bengali) or Arabic as the state language of the whole of Pakistan was also proposed, 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.

West Pakistan was the western province of Pakistan between 1955 and 1970, covering the territory of present-day Pakistan. Its land borders were with Afghanistan, India and Iran, with a maritime border with Oman in the Gulf of Oman in the Arabian Sea.

Following its independence from British rule, the new Dominion of Pakistan was physically separated into two exclaves, with the western and eastern wings geographically separated from each other by India. The western wing of Pakistan comprised three governor's provinces (the North-West Frontier, West Punjab and Sind), one chief commissioner's province (Baluchistan) along with the Baluchistan States Union, several independent princely states (notably Bahawalpur, Chitral, Dir, Hunza, Khairpur and Swat), the Karachi Federal Capital Territory, and the autonomous tribal areas adjoining the North-West Frontier Province. The eastern wing of the new country—known as East Pakistan—comprised the single province of East Bengal (which included the former Assamese district of Sylhet and the Chittagong Hill Tracts).
