Partition of Bengal (1947) in the context of "Constituent Assembly of India"

East Bengal (/bɛnˈɡɔːl/; Bengali: পূর্ব বাংলা/পূর্ববঙ্গ Purbô Bangla/Purbôbongo) was the easternmost and non-contiguous province of the Dominion of Pakistan, which covered the territory of modern-day Bangladesh. It consisted of the eastern portion of the British administrative Bengal province and the lion half of Sylhet district from the Assam province. East Bengal existed from 1947 until 1956, when it was re-structured as East Pakistan under the One Unit Scheme by the Constitution of Pakistan of 1956. East Bengal had a coastline along the Bay of Bengal to the south, and bordered India to the north, west, and east and shared a small border with Burma (presently known as Myanmar) to the southeast. It was situated near, but did not share a border with Nepal, Tibet, the Kingdom of Bhutan and the Kingdom of Sikkim. Its capital was Dacca, now known as Dhaka.

The Partition of India, which divided Bengal along religious lines, established the borders of the Muslim-majority area of East Bengal. The province existed during the reign of two monarchs, George VI and Elizabeth II; and three governors-general, Muhammad Ali Jinnah, Khawaja Nazimuddin and Ghulam Muhammad. Its provincial governors included a British administrator and several Pakistani statesmen. Its chief ministership was held by leading Bengali politicians.

The prime minister of Bengal was the head of government of Bengal Province and the Leader of the House in the Bengal Legislative Assembly in British India. The position was dissolved upon the Partition of Bengal during the partition of India in 1947.
