The 1970s (pronounced "nineteen-seventies", commonly abbreviated as the "Seventies") was a decade of the Gregorian calendar that began on 1 January 1970 and ended on 31 December 1979. It was a very significant decade in the history of Bangladesh because this is the decade in which Bangladesh emerged as a sovereign state. The decade began with a devastating cyclone that ravaged the southern part of the country. The next year the country entered into a liberation war and achieved independence from Pakistan. The government of Sheikh Mujibur Rahman administered the newly formed country between 1972 and 1975, but their rule soon came to an end through a series of coups and countercoups in the later part of the decade. Economically, the country struggled because of the war (1971) and famine (1974) throughout the decade and was highly dependent on foreign aid. Culturally, Bangladesh started to establish its own identity as an independent nation.

Politics and national life Tension between the two factions of Pakistan

The 1970s started with Bangladesh as part of erstwhile Pakistan amid intense political tension between the two factions of the country - East (later Bangladesh) and the West (later Pakistan). The East Pakistanis observed that the West Pakistani establishment would swiftly depose any East Pakistani elected Prime Minister of Pakistan, such as Khawaja Nazimuddin, Mohammad Ali Bogra, or Huseyn Shaheed Suhrawardy. Their suspicions were further aggravated by the military dictatorships of Ayub Khan (27 October 1958 – 25 March 1969) and Yahya Khan (25 March 1969 – 20 December 1971), both West Pakistanis. The situation reached a climax in 1970, when the Bangladesh Awami League, the largest East Pakistani political party, led by Sheikh Mujibur Rahman, won a landslide victory in the national elections. The party won 167 of the 169 seats allotted to East Pakistan, and thus a majority of the 313 seats in the National Assembly. This gave the Awami League the constitutional right to form a government. However, Zulfikar Ali Bhutto (a former Foreign Minister), the leader of the Pakistan Peoples Party, refused to allow Rahman to become the Prime Minister of Pakistan. Instead, he proposed the idea of having two Prime Ministers, one for each wing. The proposal elicited outrage in the east wing, already chafing under the other constitutional innovation, the "One Unit scheme". Bhutto also refused to accept Rahman's Six Points. On 3 March 1971, the two leaders of the two wings along with the President General Yahya Khan met in Dacca to decide the fate of the country. After their discussions yielded no satisfactory results, Sheikh Mujibur Rahman called for a nationwide strike. Bhutto feared a civil war, therefore, he sent his trusted companion, Mubashir Hassan. A message was conveyed, and Rahman decided to meet Bhutto. Upon his arrival, Rahman met with Bhutto and both agreed to form a coalition government with Rahman as Premier and Bhutto as president. However, the military was unaware of these developments, and Bhutto increased his pressure on Rahman to reach a decision.

The talks proved unsuccessful, however, and on 1 March 1971, Pakistani President Yahya Khan indefinitely postponed the pending National Assembly session, precipitating massive civil disobedience in East Pakistan.

On 2 March 1971, a group of students, led by A S M Abdur Rob, a student leader, raised the new (proposed) flag of Bangladesh under the direction of the Swadhin Bangla Nucleus. They demanded that Sheikh Mujibur Rahman declare the independence of Bangladesh immediately but Mujibur Rahman refused to agree to this demand. Rather, he decided that he would declare his next steps at a public meeting to be held on 7 March.

On 3 March, student leader, Shahjahan Siraj, read the 'Sadhinotar Ishtehar' (Declaration of independence) at Paltan Maidan in front of Bangabandhu Sheikh Mujib at a public gathering under the direction of the Swadhin Bangla Nucleus.

On 7 March, there was a public gathering in Suhrawardy Udyan to hear updates on the ongoing movement from Bangabandhu Sheikh Mujib, the leader of the movement that time. Although he avoided directly referring to independence, as the talks were still underway, he warned his listeners to prepare for any imminent war. The speech is considered a key moment in the war of liberation, and is remembered for the phrase,

"Ebarer Shongram Amader Muktir Shongram, Ebarer Shongram Shadhinotar Shongram...." "Our struggle this time is a struggle for our freedom, our struggle this time is a struggle for our independence...."

Bhola cyclone

The 1970 Bhola cyclone made landfall on the East Pakistan coastline during the evening of 12 November, around the same time as a local high tide, killing an estimated 300,000 to 500,000 people. Though the exact death toll is not known, it is considered the deadliest tropical cyclone on record. A week after the landfall, President Khan conceded that his government had made "slips" and "mistakes" in its handling of the relief efforts due to a lack of understanding of the magnitude of the disaster.

A statement released by eleven political leaders in East Pakistan ten days after the cyclone hit charged the government with "gross neglect, callous and utter indifference". They also accused the president of playing down the magnitude of the problem in news coverage. On 19 November, students held a march in Dacca protesting the slowness of the government's response. Abdul Hamid Khan Bhashani addressed a rally of 50,000 people on 24 November, where he accused the president of inefficiency and demanded his resignation.

As the conflict between East and West Pakistan developed in March, the Dacca offices of the two government organisations directly involved in relief efforts were closed for at least two weeks, first by a general strike and then by a ban on government work in East Pakistan by the Awami League. With this increase in tension, foreign personnel were evacuated over fears of violence. Relief work continued in the field, but long-term planning was curtailed. This conflict widened into the Bangladesh Liberation War in December and concluded with the creation of Bangladesh. This was one of the first times that a natural event helped trigger a civil war.

Formal declaration of independence

In the early hours of 26 March 1971, a military crackdown by the Pakistan army began. The Bangabandhu Sheikh Mujibur Rahman was arrested, and the political leaders dispersed, mostly fleeing to neighbouring India, where they organised a provisional government. Before being arrested by the Pakistani Army, Sheikh Mujibur Rahman passed a hand written note which contained the Bangladeshi Declaration of Independence. This note was widely circulated and transmitted by the then East Pakistan Rifles' wireless transmitter. The world press reports from late March 1971 also make sure that Bangladesh's declaration of independence by Bangabandhu was widely reported throughout the world. Bengali Army officer Major Ziaur Rahman captured the Kalurghat Radio Station in Chittagong and read the declaration of independence of Bangladesh during the evening hours on 27 March.

This is Swadhin Bangla Betar Kendra. I, Major Ziaur Rahman, at the direction of Bangobondhu Mujibur Rahman, hereby declare that the Independent People's Republic of Bangladesh has been established. At his direction, I have taken command as the temporary Head of the Republic. In the name of Sheikh Mujibur Rahman, I call upon all Bengalees to rise against the attack by the West Pakistani Army. We shall fight to the last to free our motherland. Victory is, by the Grace of Allah, ours. Joy Bangla.

The Provisional Government of the People's Republic of Bangladesh was formed on 10 April in Meherpur (later renamed as Mujibnagar, a town adjacent to the Indian border). Sheikh Mujibur Rahman was announced to be the Head of the State. Tajuddin Ahmed became the Prime Minister, Syed Nazrul Islam became the acting president and Khondaker Mostaq Ahmed the Foreign Minister. There the war plan was sketched out with Bangladesh armed forces established and named "Muktifoujo". Later these forces were named "Muktibahini" (freedom fighters). M. A. G. Osmani was appointed as the Chief of the Armed Forces.

For military purposes, Bangladesh was divided into 11 sectors under 11 sector commanders. In addition to these sectors, later in the war, three special forces were formed: Z Force, S Force and K Force. These three forces' names were derived from the initial letters of the commander's name. The training and most of the arms and ammunitions were arranged by the Meherpur government which was supported by India. As fighting grew between the Pakistan Army and the Bengali Mukti Bahini, 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 pressure of millions of refugees escaping into India in autumn 1971, as well as Pakistani aggression, reignited Indian hostilities with Pakistan. Indian sympathies lay with East Pakistan, and on 3 December 1971, India intervened on the side of the Bangladeshis which led to a short, but violent, two-week war known as the Indo-Pakistani War of 1971.

Pakistani capitulation and aftermath

On 16 December 1971, Lt. Gen A. A. K. Niazi, CO of Pakistan Army forces located in East Pakistan signed the Instrument of Surrender and the nation of Bangla Desh ("Country of Bengal") was finally established the following day. At the time of surrender only a few countries had provided diplomatic recognition to the new nation. Over 90,000 Pakistani troops surrendered to the Indian forces making it the largest surrender since World War II. The new country changed its name to Bangladesh on 11 January 1972 and became a parliamentary democracy under a constitution. Shortly thereafter on 19 March Bangladesh signed a friendship treaty with India. Bangladesh sought admission in the UN with most voting in its favour, but China vetoed this as Pakistan was its key ally.Section 9. Situation in the Indian Subcontinent, 2. Bangladesh's international position – Ministry of Foreign Affairs of Japan To ensure a smooth transition, in 1972 the Simla Agreement was signed between India and Pakistan. The treaty ensured that Pakistan recognised the independence of Bangladesh in exchange for the return of the Pakistani PoWs. India treated all the PoWs in strict accordance with the Geneva Convention, rule 1925. It released more than 93,000 Pakistani PoWs in five months.

Furthermore, as a gesture of goodwill, nearly 200 soldiers who were sought for war crimes by Bengalis were also pardoned by India. The accord also gave back more than of land that Indian troops had seized in West Pakistan during the war, though India retained a few strategic areas; most notably Kargil (which would in turn again be the focal point for a war between the two nations in 1999).

Sheikh Mujibur Rahman administration

Upon his release on 10 January 1972, Sheikh Mujibur Rahman briefly assumed the provisional presidency and later took office as the prime minister, heading all organs of government and decision-making. The politicians elected in 1970 formed the provisional parliament of the new state. The Mukti Bahini and other militias amalgamated to form a new Bangladeshi army to which Indian forces transferred control on 17 March. The government faced serious challenges, which including the rehabilitation of millions of people displaced in 1971, organising the supply of food, health aids and other necessities. The effects of the 1970 cyclone had not worn off, and the state's economy had immensely deteriorated by the conflict.
