Vijay Diwas or Victory Day is celebrated in India every year on December 16 to commemorate the victory of the Indian armed forces over Pakistan in the 1971 Indo-Pak War, also known as the Bangladesh Liberation War.
The India-Pakistan war began on 3 December 1971 and ended on 16 December 1971. It was one of the shortest wars (13 days) but saw one of the biggest surrenders.
India’s role in Bangladesh’s creation :
The 13-day Indo-Pak War was sparked by the rebellion in erstwhile East Pakistan against the government in Islamabad.
Since March 1971, Bengali nationalists had been fighting a brutal crackdown by Pakistani forces on the civil and political rights of the Bengali population.
Then Indian Prime Minister Indira Gandhi had provided support to the Bangladesh cause for months but the Indian military formally engaged in a full-scale war with Pakistan on December 3.
Soon, foreign pressure to end the war and mounting losses forced Islamabad to accept defeat, thereby granting Bangladesh full independence.
