In the
1970 Pakistani general election, held under the military government of President
Yahya Khan, the
Awami League—led by
Sheikh Mujibur Rahman—won a clear majority in both the national and provincial assemblies of
East Pakistan.
Zulfikar Ali Bhutto conspired with Yahya Khan and changed their position, refusing to hand over power to Sheikh Mujib. After the Pakistan Government's poor response to the
1970 Bhola cyclone which left over 500,000 people dead,
Abdul Hamid Khan Bhashani a prominent political figure who had previously led multiple rebellion against the
British Raj was the first ever Bengali to declare independence of East Pakistan in a massive public rally on 23 November 1970 but it was not officially recognized. Negotiations began between the two sides, however the ruling West Pakistani leadership did not trust Sheikh Mujib, due to instances such as the
Agartala conspiracy case. When it became evident that the promises made by the West Pakistan government were not going to be kept, many East Pakistani Bangla-speaking Muslims and Hindus began a spirited struggle for independence. On 7 March 1971, Sheikh Mujibur Rahman gave his
famous speech at the
Ramna Racecourse, in which he called for a
non-cooperation movement. Authorities, mostly West Pakistani personnel, rounded up Bengali armed forces officers,
NCOs, and enlisted personnel. Forced disappearances were rampant. On the night of 25 March, the
Pakistan Army began
Operation Searchlight, conclusively signalling West Pakistan was not ready for a transfer of political power to the Awami League led by Sheikh Mujibur Rahman. The then major
Ziaur Rahman declared the
independence of Bangladesh on behalf of Sheikh Mujibur Rahman at
Kalur Ghat Radio Station on 27 March 1971. Major Zia (who was also a BDF Sector Commander of Sector 1 and later of Sector 11) raised an independent Z Force brigade, Chittagong and the guerrilla struggle officially began. The
Mukti Bahini, later with military support from India, defeated the Pakistan Army on 16 December 1971, leading to the end of the war and the
Surrender of Pakistan. ==Celebrations==
