In which year did Bangladesh become an independent country?

Bangladesh (officially the People's Republic of Bangladesh) is a country in South Asia. It shares land borders with India and Myanmar (Burma). Nepal, Bhutan and China are located near Bangladesh but do not share a border with it. The country's maritime territory in the Bay of Bengal is roughly equal to the size of its land area. Bangladesh is the world's eighth most populous country. Dhaka is its capital and largest city, followed by Chittagong, which has the country's largest port. Bangladesh forms the largest and easternmost part of the Bengal region.

During the Bangladesh Liberation War, Bengali nationalists declared independence and formed the Mukti Bahini (the Bangladeshi National Liberation Army). The Provisional Government of Bangladesh was established on 17 April 1971, converting the 469 elected members of the Pakistani national assembly and East Pakistani provincial assembly into the Constituent Assembly of Bangladesh. The provisional government issued the Proclamation of Bangladeshi Independence, which was the country's interim constitution and declared "equality, human dignity and social justice" as its fundamental principles.
