(1972-75)

Mujib came to office with immense personal popularity but had difficulty transforming this popular support into the political strength needed to function as head of government. The new constitution, which came into force in December 1972, created a strong executive prime minister, a largely ceremonial presidency, an independent judiciary, and a unicameral legislature on a modified Westminster model. The 1972 constitution adopted as state policy the Awami League's (AL) four basic principles of nationalism, secularism, socialism, and democracy.

The first parliamentary elections held under the 1972 constitution were in March 1973, with the Awami League winning a massive majority. No other political party in Bangladesh's early years was able to duplicate or challenge the League's broad-based appeal, membership, or organizational strength.

Relying heavily on experienced civil servants and members of the Awami League, the new Bangladesh Government focused on relief, rehabilitation, and reconstruction of the economy and society. Economic conditions remained precarious, however. In December 1974, Mujib decided that continuing economic deterioration and mounting civil disorder required strong measures. After proclaiming a state of emergency, Mujib used his parliamentary majority to win a constitutional amendment limiting the powers of the legislative and judicial branches, establishing an executive presidency, and instituting a one-party system, the Bangladesh Krishak Sramik Awami League (BAKSAL), which all members of parliament were obliged to join.

Despite some improvement in the economic situation during the first half of 1975, implementation of promised political reforms was slow, and criticism of government policies became increasingly centered on Mujib. In August 1975, Mujib and most of his family were assassinated by mid-level army officers. His daughter, Sheikh Hasina, happened to be out of the country. A new government, headed by former Mujib associate Khandakar Moshtaque, was formed.
