Mujibnagar , formerly known as Baidyanathtala is a town in the Meherpur District of Bangladesh. It is a common reference for the government in exile formed by the leaders of the Awami League, who were leading the guerrilla war for the independence of Bangladesh (then East Pakistan) from Pakistan in 1971.
Throughout the war with the Pakistan Army, the Mujibnagar government would serve as the nominal head of the pro-independence guerrilla militias, mainly the Mukti Bahini. Although the state gained independence that was recognized by other countries only in December 1971, the Mujibnagar government is recognized as the first official government of Bangladesh.The Vice President of Bangladesh, Syed Nazrul Islam, performed the ceremony at Mujibnagar in the role of Acting President, because the President, Sheikh Mujibur Rahman, was detained in Pakistan throughout the war.
