The Siliguri Corridor, often dubbed the "Chicken's Neck", is a stretch of land around the city of Siliguri in West Bengal, India. 20–22 kilometres (12–14 mi) at the narrowest section, this geopolitical and geoeconomical corridor connects the seven states of northeast India to the rest of India. The countries of Nepal and Bangladesh lie on each side of the corridor and the Kingdom of Bhutan lies at the northern end of the corridor. The Kingdom of Sikkim formerly lay on the northern side of the corridor, until its merger with India in 1975.

The city of Siliguri is the major city in the area and the central transfer point connecting Bhutan, Nepal, Bangladesh, Sikkim, Darjeeling, Northeast India and mainland India. According to the Indian Army, the Siliguri Corridor is the Army's strongest defensive line.

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.
