The history of Bangladesh after independence begins in 1971 with the independence of Bangladesh from Pakistan.
Upon assuming the presidency after his release, Sheikh Mujib 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.
Mujib helped Bangladesh enter into the United Nations and the Non-Aligned Movement. He travelled to the United States, the United Kingdom and other European nations to obtain humanitarian and developmental assistance for the nation. He signed a treaty of friendship with India, which pledged extensive economic and humanitarian assistance and began training Bangladesh's security forces and government personnel. Mujib forged a close friendship with Indira Gandhi, strongly praising India's decision to intercede, and professed admiration and friendship for India. Major efforts were launched to rehabilitate an estimated 10 million refugees. The economy began recovering and a famine was prevented. A constitution was proclaimed in 1973 and elections were held, which resulted in Mujib and his party gaining power with an absolute majority. He further outlined state programmes to expand primary education, sanitation, food, healthcare, water and electric supply across the country. A five-year plan released in 1973 focused state investments into agriculture, rural infrastructure and cottage industries.
In 1974, Bangladesh experienced the deadliest famine ever, which killed around 1.5 million Bangladeshi people from hunger. The Bangladesh famine of 1974 is a major source of discontent against Mujib's government. Bangladeshi people feel ashamed, insulted and demoralised as a nation for this famine that was not due to a food crisis.
