Provisional Government of Bangladesh

The Provisional Government of Bangladesh, popularly known as the Mujibnagar Government and also known as the Bangladeshi government-in-exile, was the first and founding government of Bangladesh that was established following the proclamation of independence of East Pakistan as Bangladesh on 10 April 1971. Headed by prime minister Tajuddin Ahmad, it was the supreme leadership of the liberation movement, comprising a cabinet, a diplomatic corps, an assembly, an armed force, and a radio service. It operated as a government-in-exile from Kolkata. The president of this government was Sheikh Mujibur Rahman, who is the main undisputed figure here; however, in his absence, Syed Nazrul Islam became the acting president.

After the 1970 general election, the military administration of Pakistan failed to hand over power to the elected legislators. When the Pakistan Army launched operations against separatists, the elected political leadership of East Pakistan declared independence and founded the provisional government with the support of the Government of India. Its cabinet took oath on 17 April 1971 in the town of Mujibnagar. It attracted many defectors from the Pakistani civil, diplomatic and military services and many leading intellectuals and cultural figures from East Pakistan.

The Mujibnagar government coordinated the war efforts of the Mukti Bahini and the nascent Bangladesh Armed Forces. It had its own postal service. Its public relations strategy featured a widely popular radio station known as Swadhin Bangla Betar Kendra. It coordinated with the Government of India in conducting the armed resistance against the Pakistan army and also addressing the refugee crisis. It also undertook an international campaign to garner support for Bangladesh's independence, calling for stopping the genocide and preventing a refugee crisis. It appointed special envoys and operated representative missions in New Delhi, Washington, D.C., and London among many other cities.
