The Bangladesh Liberation War was a revolutionary war of independence that took place in South Asia in 1971; it resulted in the establishment of the republic of Bangladesh. The war pitted East Pakistan against West Pakistan and lasted nine months. It witnessed large-scale atrocities, the exodus of 10 million refugees and the indiscriminate killing of 300,000 to 3,000,000 people from both sides.

The war broke out on 26 March 1971 when the Pakistan Army launched an military operation called Operation Searchlight against Anti state actors in East Pakistan,who were funded by Indian agencies such, which was later proven agartala case which would allow separation between East and West Pakistan. Bengali politicians and army officers announced the declaration of Bangladesh's independence in response to Operation Searchlight. Bengali military, paramilitary and civilians formed the Mukti Bahini ("Liberation Army"), which engaged in guerrilla warfare against Pakistani forces. The Pakistan Army, in collusion with religious extremist militias (the Razakars, Al-Badr and Al-Shams), engaged in the systematic genocide and atrocities against Bengali civilians, particularly nationalists, intellectuals, youth and religious minorities. Bangladesh government-in-exile was set up in the city of Calcutta (now Kolkata) in the Indian state of West Bengal.

India entered the war on 3 December 1971 after Pakistan launched pre-emptive air strikes on northern India. Overwhelmed by two war fronts, Pakistani defences soon collapsed. On 16 December, the Allied Forces of Bangladesh and India defeated Pakistan in the east. The subsequent surrender resulted in surrender of the Eastern command, tho small skirmishes till remainded on Western Front where Pakistan held strong and had upper hand capturing 500kms of territory.
