Victory Day (Bangladesh) in the context of "Independence of Bangladesh"

The Pakistani Instrument of Surrender (Bengali: পাকিস্তানের আত্মসমর্পণের দলিল, romanized: Pākistānēr Ātmôsômôrpôṇēr Dôlil) was a legal document signed between India (alongside the Provisional Government of Bangladesh) and Pakistan to end the Bangladesh Liberation War and the Indo-Pakistani War of 1971. Per the trilateral agreement, the Pakistani government surrendered the Armed Forces Eastern Command, thereby enabling the establishment of the People's Republic of Bangladesh over the territory of East Pakistan. The document was signed by India's Lt. Gen Jagjit Singh Aurora and Pakistan's A. A. K. Niazi, and led to the surrender of 93,000 Pakistanis — the world's largest surrender in terms of number of personnel since World War II. Despite the agreement, Pakistan did not formally recognize Bangladeshi sovereignty until February 1974.

The ratification of the agreement by all sides also marked the end of the Bangladesh genocide, perpetrated by Pakistan during the conflict. Bangladesh and the Indian Armed Forces celebrate Pakistan's 1971 defeat and surrender on an annual basis, observing 16 December as Victory Day.

The independence of Bangladesh was declared from Pakistan on 26 March 1971, which is now celebrated as Independence Day. The Bangladesh Liberation War started on 26 March and lasted till 16 December 1971 which is celebrated as Victory Day in Bangladesh.
