The 1971 Bangladesh Liberation War (Bengali: মুক্তিযুদ্ধ Muktijuddho) was a war of independence,[2] which resulted in the secession of East Pakistan from the Islamic Republic of Pakistan[3] and established the sovereign nation called Bangladesh. The war pitted East Pakistan and India against West Pakistan, and lasted over a duration of nine months. One of the most violent wars of the 20th century, it witnessed large-scale atrocities, the exodus of 10 million refugees and the Killing of 3 million people.

On 16 December 1971, Lieutenant General Amir Abdullah Khan Niazi, CO of Pakistan Armed Forces located in East Pakistan signed the Instrument of Surrender. The Instrument of Surrender was a written agreement that enabled the surrender of the Pakistan Eastern Command in the Bangladesh Liberation War, and marked the end of the Indo-Pakistani War of 1971 in the Eastern Theater.
