Formal Declaration of Independence

After the military crackdown by the Pakistan army began on the night of March 25, 1971 Bangabandhu Sheikh Mujibur Rahman was arrested and the political leaders dispersed, mostly fleeing to neighbouring India where they organized a provisional government afterwards. Before being held up by the Pakistani Army Sheikh Mujibur Rahman gave a hand note of the declaration of the independence of Bangladesh and it was circulated amongst people and transmitted by the the then East Pakistan Rifles' wireless transmitter. In chittagong on behalf of Sheikh Mujibur Rahman, Awami League Leader M. A. Hannan first read the declaration of independence on the Radio. A few Bangalee Radio Professionals organized together to build up Shadhin Bangla Betar Kendro ( Radio Station of Independent Bengal) and asked the Bengali Army Major Zia-Ur-Rahman to read the declaration of independence of Bangladesh on the independent Radio. On 27th march Major Zia read the declaration of independence on behalf of Sheikh Mujibur Rahman, "I, Major Zia-ur-Rahman, who hereby declare the independence of Bangladesh, on behalf of our great national leader Bangabandhu Sheikh Mujibur Rahman".The Bangladesh Government was formed in Meherpur, (later renamed as Mujibnagar a place adjacent to the Indian Border). Sheikh Mujibur Rahman was announced to be the head of the state. Tajuddin Ahmed became the prime minister of the government. There the war plan was sketched.A war force was established named "Muktibahini". M. A. G. Osmani was assigned as the Chief of the force. The land sketched into 11 sectors under 11 sector commanders. Along with this sectors on the later part of the war Three special forces were formed namely Z Force, S Force and K Force. These three forces name were derived from the initial letter of the commandar's name.The training and most of the arms-ammunitions were arranged by the Meherpur government which were supported by India.As fighting grew between the Pakistan Army and the Bengali Mukti Bahini ("freedom fighters"), an estimated ten million Bengalis, mainly Hindus, sought refuge in the Indian states of Assam, Tripura and West Bengal.The crisis in East Pakistan produced new strains in Pakistan's troubled relations with India. The two nations had fought a war in 1965, mainly in the west, but the refugee pressure in India in the fall of 1971 produced new tensions in the east. Indian sympathies lay with East Pakistan, and on December 3, 1971, India intervened on the side of the Bangladeshis. On December 16, 1971, Pakistani forces surrendered, and Bangla Desh ("Country of Bangla") was finally established the following day. The new country changed its name to Bangladesh on January 11, 1972 and became a parliamentary democracy under a constitution. Shortly thereafter on March 19 Bangladesh signed a friendship treaty with India.
