Following the Pakistan Army crackdown on 25 March, Awami League leaders
Tajuddin Ahmad, general secretary of the party, and
M Amir-ul Islam escaped Dhaka and crossed the Indian border on 30 March. They were received at the border outpost by the regional head of the Indian
Border Security Force (BSF), Golok Majumdar. Majumdar immediately transported them to
Kolkata with him. There, on the night of 30 March and the next day, Tajuddin and Amir had discussions with BSF chief
Khusro Faramurz Rustamji, who had come from
Delhi after learning of their arrival. On 1 April, Tajuddin and Islam, accompanied by Majumdar, left for Delhi aboard a military cargo plane. In Delhi, Tajuddin met with India's Prime Minister
Indira Gandhi, on 4 April. At their second meeting the following day, Gandhi informed him that Sheikh Mujib had been arrested and transported to Pakistan though Pakistan had not made this official yet. Asked about the Bangladesh government, he replied, having consulted with Amir-ul Islam the day before, that a provisional government had been formed with Sheikh Mujib as its president with the senior Awami League leaders who had attended the Mujib-Yahya talks as cabinet members. Tajuddin presented himself as the prime minister. Except for Sheikh Mujib, the whereabouts of the other members was unknown. Two crucial resolutions were reached in that meeting: India opened its borders to Bangladeshi refugees saving millions of lives in the upcoming days when Pakistani aggression reached outside major cities, and India allowed the Bangladesh Government to operate within Indian territory. The Indian government also promised to help the Bangladeshi liberation war by any means possible. While Tajuddin was in Delhi, part of the Awami League leadership congregated in Kolkata. Many of them, notably the youth and student leaders, viewed Tajuddin's meeting with the Indian prime minister as an outrageous act side-lining them. On returning to Kolkata, on 8 April, Tajuddin found and met the group of leaders, including
Abul Hasnat Muhammad Qamaruzzaman, and informed them of the Delhi meeting's outcomes, including the provisional government. Some of the leadership present there questioned Tajuddin's legitimacy as prime minister. The youth leader
Sheikh Mani rejected the idea of the cabinet outright. Instead, he proposed setting up a revolutionary council dedicated to conducting armed resistance only. Amir-ul Islam explained the inadequacy of the revolutionary council and the necessity of a legal government. After this, and following Qamaruzzaman's mediation, most of the leadership at the meeting accepted Tajuddin's proposal. On 10 April, Tajuddin, Amir-ul Islam, Sheikh Mani and others boarded an old
Douglas C-47 Skytrain plane borrowed from the Indian government and set off in search of other cabinet members scattered around the borders. Flying at low altitudes, the plane stopped at various airstrips at the borders. After picking up cabinet members
Muhammad Mansur Ali,
Abdul Mannan, and
Syed Nazrul Islam from various places on the way, on 11 April, the entourage arrived in
Agartala, capital of the Indian state of
Tripura, where many other Awami League leaders had taken refuge, including
Khondaker Mostaq Ahmad and Colonel
M. A. G. Osmani. Reunited in Agartala, the Awami League leadership pondered the cabinet agenda and distributing cabinet offices. In the absence of President Sheikh Mujib, Syed Nazrul Islam served as acting president, Khondaker Mostaq took the Ministry of Foreign Affairs, Qamarauzzaman was given the State Minister's office, Mansur Ali the Finance Ministry, Abdul Mannan took his responsibility as the Minister-In-Charge of Information and Broadcasting Ministry, and Osmani, a retired veteran of the Pakistan army, was appointed commander-in-chief of the armed forces. The entire cabinet returned to Kolkata on 13 April, set to take oath at some yet unoccupied place in Bangladesh. The oath taking ceremony took place on 17 April, at a village along the India-Bangladesh border, called
Baidyanathtala, in
Kushtia district (currently
Meherpur district), on Bangladeshi soil. The ceremony was conducted by
Abdul Mannan. Professor
Muhammad Yusuf Ali read the
proclamation of independence, drafted by Amir-ul Islam, an Awami League
MNA-elect and
barrister of the
Dacca High Court, with the help of
Subrata Roy Chowdhury, a barrister of the
Calcutta High Court, retroactively in effect from 10 April. Answering a journalist during the ceremony, Tajuddin named the place
Mujibnagar, after Sheikh Mujibur Rahman. Later the government-in-exile came to be popularly known as the Mujibnagar Government. Mujibnagar was abandoned quickly after the oath ceremony as participants feared a raid by Pakistani forces. The government settled in Kolkata, in exile, for the rest of the war—briefly at a house on Ballyganj Circular Road and then at 8 Theatre Road. ==Constitution==
