The country Mujib returned to was scarred by civil war . The number of people killed , raped , or displaced could be only vaguely estimated . The task of economic rehabilitation , specifically the immediate goal of food distribution to a hungry populace , was frustrated by crippled communications and transportation systems . The new nation faced many other seemingly insurmountable problems inhibiting its reconstruction . One of the most glaring was the breakdown of law and order . In the wake of the war of independence , numerous bands of guerrillas still roamed the countryside , fully armed and outside the control of the government . Many fighters of the Mukti Bahini joined the Bangladesh Army and thus could legally retain their weapons , but many others ignored Mujib's plea that they surrender their weapons . Some armed groups took the law into their own hands and set up territories under their own jurisdiction . In time these challenges to central authority contributed to Mujib's suspension of democracy .
Mujib had an unfailing attachment to those who participated in the struggle for independence . He showed favoritism toward those comrades by giving them appointments to the civil government and especially the military . This shortsighted practice proved fatal . Mujib denied himself the skill of many top-level officers formerly employed by the Pakistan Civil Service. Bengali military officers who did not manage to escape from West Pakistan during the war and those who remained at their posts in East Pakistan were discriminated against throughout the Mujib years. The "repatriates," who constituted about half of the army, were denied promotions or choice posts; officers were assigned to functionless jobs as "officers on special duty." Schooled in the British tradition, most believed in the ideals of military professionalism; to them the prospect of serving an individual rather than an institution was reprehensible. Opposed to the repatriates were the freedom fighters, most of whom offered their unquestioning support for Mujib and in return were favored by him. A small number of them, associated with the radical Jatiyo Samajtantrik Dal (National Socialist Party), even proposed that officers be elected to their posts in a "people's army." From the ranks of the freedom fighters, Mujib established the Jatiyo Rakkhi Bahini (National Defense Force), whose members took a personal pledge to Mujib and became, in effect, his private army to which privileges and hard-to-get commodities were lavishly given.
Despite substantial foreign aid, mostly from India and the Soviet Union, food supplies were scarce, and there was rampant corruption and black marketeering. This situation prompted Mujib to issue a warning against hoarders and smugglers. Mujib backed up his threat by launching a mass drive against hoarders and smugglers, backed by the Jatiyo Rakkhi Bahini. The situation only temporarily buoyed the legitimate economy of the country, as hoarding, black marketeering, and corruption in high offices continued and became the hallmarks of the Mujib regime.
Mujib's economic policies also directly contributed to his country's economic chaos. His large-scale nationalization of Bangladeshi manufacturing and trading enterprises and international trading in commodities strangled Bangladesh entrepreneurship in its infancy. The enforced use of the Bangla language as a replacement for English at all levels of government and education was yet another policy that increased Bangladesh's isolation from the dynamics of the world economy.
Most Bangadeshis still revered the Bangabandhu at the time of the first national elections held in 1973. Mujib was assured of victory, and the Awami League won 282 out of 289 directly contested seats. After the election, the economic and security situations began to deteriorate rapidly, and Mujib's popularity suffered further as a result of what many Bangladeshis came to regard as his close alliance with India. Mujib's authoritarian personality and his paternalistic pronouncements to "my country" and "my people" were not sufficient to divert the people's attention from the miserable conditions of the country. Widespread flooding and famine created severe hardship, aggravated by growing law-and-order problems.
In January 1975, the Constitution was amended to make Mujib president for five years and to give him full executive powers. The next month, in a move that wiped out all opposition political parties, Mujib proclaimed Bangladesh a one-party state, effectively abolishing the parliamentary system. He renamed the Awami League the Bangladesh Krishak Sramik Awami League (Bangladesh Peasants, Workers, and People's League) and required all civilian government personnel to join the party. The fundamental rights enumerated in the Constitution ceased to be observed, and Bangladesh, in its infancy, was transformed into a personal dictatorship.
On the morning of August 15, 1975, Mujib and several members of his family were murdered in a coup engineered by a group of young army officers, most of whom were majors. Some of the officers in the "majors' plot" had a personal vendetta against Mujib, having earlier been dismissed from the army. In a wider sense, the disaffected officers and the several hundred troops they led represented the grievances of the professionals in the military over their subordination to the Jatiyo Rakkhi Bahini and Mujib's indifference to gross corruption by his political subordinates and family members. By the time of his assassination, Mujib's popularity had fallen precipitously, and his death was lamented by surprisingly few.
The diplomatic status of Bangladesh changed overnight. One day after Mujib's assassination President Bhutto of Pakistan announced that his country would immediately recognize the new regime and offered a gift of 50,000 tons of rice in addition to a generous gift of clothing. India, however, under the rule of Indira Gandhi, suffered a setback in its relations with Bangladesh. The end of the Mujib period once again brought serious bilateral differences to the fore. Many Bangladeshis, although grateful for India's help against Pakistan during the struggle for independence, thought Indian troops had lingered too long after the Pakistan Army was defeated. Mujibist dissidents who continued to resist central authority found shelter in India .
