After a nine-month war, resulting in a free, independent, and sovereign Bangladesh. The fury of the Bengali population was compounded when Sheikh Mujibur Rahman who led Awami League to win a majority in Parliament in the 1970 elections, was blocked from taking office. A massive civil disobedience movement erupted across East Pakistan, with open calls for independence. Sheikh Mujibur Rahman address
ed a huge pro-independence rally in Dacca on 7 March 1971. The Bangladeshi flag was hoisted for the first time on 23 March 1971, Pakistan's Republic Day. On 26 March 1971, the Pakistani military junta led by Yahya Khan launched Operation Searchlight, a sustained military assault on East Pakistan, and detained the Prime Minister-elect under military custody. The Pakistan Army, with the help of supporting militias, massacred Bengali students, intellectuals, politicians, civil servants and military defectors during the 1971 Bangladesh genocide. Estimates for those killed throughout the war range between 300,000 and 3 million. Global public opinion turned against Pakistan as news of atrocities spread, with the Bangladesh Movement gaining support from prominent political and cultural figures in the West, including Ted Kennedy, George Harrison, Bob Dylan, Joan Baez, Victoria Ocampo and Andre Malraux. The Concert for Bangla Desh was held at Madison Square Garden in New York City to raise funds for Bangladeshi refugees. It was the first major benefit concert in history and was organized by Beatles star George Harrison and Indian Bengali sitarist Ravi Shankar. During the liberation war, Bengali nationalists announced a declaration of independence and formed the Mukti Bahini (the Bangladeshi National Liberation Army). The Provisional Government of Bangladesh operated in exile from Calcutta, India. Osmani and eleven Sector Commanders, the Mukti Bahini held the Bengali countryside during the war, and waged wide-scale guerrilla operations against Pakistani forces. Neighboring India and its leader Indira Gandhi, a longstanding nemesis of Pakistan, provided crucial support to the Bangladesh Forces and intervened in support of the provisional government on 3 December 1971. The Soviet Union and the United States dispatched naval forces to the Bay of Bengal amid a Cold War standoff during the Indo-Pakistani War. Lasting for nine months, the entire war ended with the surrender of Pakistan's military to the Bangladesh-India Allied Forces on 16 December 1971. Under international pressure, Pakistan released Mujib from imprisonment on 8 January 1972, after which he was flown by the Royal Air Force to a million strong homecoming in Dhaka. Indian troops were withdrawn by 12 March 1972, three months after the war ended. The cause of Bangladeshi self-determination was widely recognized around the world. By the time of its admission for UN membership in August 1972, the new state was recognized by 86 countries. Pakistan recognized Bangladesh in 1974 after pressure from most of the Muslim world. National Anthems
Amar Shonar Bangla (My Golden Bengal) (Bangla:আমার সোনার বাংলা) is a 1906 song written and composed by the poet Rabindranath Tagore, the first ten lines of which were adopted in 1972 as the Bangladesh national anthem. The word shonar literally means 'made of gold', but in the song shonar Bangla may be interpreted to either express the preciousness of Bengal or a reference to the colour of paddy fields before harvest. The song was written in 1906 during the period of Bongobhanga (Bôngobhôngo - 1905 Partition of Bengal) - when Bengal was divided in two halves by the British government based on religion. This song, along with a host of others, was written to rekindle the unified spirit of Bengal. It is said that the music of this song was inspired by the Baul singer Gagan Harkara's song "Kothay Pabo Tare". (Bangla:কোথায় পাবো তারে)[citation needed]
The first 10 lines of this song constitute the national anthem of Bangladesh. It was adopted in 1972 after the independence of Bangladesh.
