Mujibnagar, formerly known as Baidyanathtala (Boiddonathtola) and Bhoborpara, is a town in the Mujibnagar Upazila of Meherpur District in Khulna, Bangladesh. The Provisional Government of Bangladesh was formed on 10 April 1971, however, sworn in on 17 April 1971 in this place by the elected representatives of the Bengalees, that led the Bangladesh Liberation War, who were leading the guerrilla war for the independence of Bangladesh from Pakistan in 1971. The place was renamed Mujibnagar by the proclamation of independence, in honour of then imprisoned Sheikh Mujibur Rahman, who had declared Bangladesh independent. The actual capital of the government while in exile was Calcutta. A memorial complex covering 20.10 acres (8.13 ha) has been built at the site where the ministers of that first government took their oaths.
