The constituent assembly adopted the constitution of Bangladesh on 4 November 1972, establishing a secular, multiparty parliamentary democracy. The new constitution included references to socialism, and Prime Minister Sheikh Mujibur Rahman nationalised major industries in 1972. A major reconstruction and rehabilitation program was launched. The Awami League won the country's first general election in 1973, securing a large majority in the "Jatiyo Sangshad", the national parliament. Bangladesh joined the Commonwealth of Nations, the UN, the OIC and the Non-Aligned Movement, and Rahman strengthened ties with India. Amid growing agitation by the opposition National Awami Party and Jashod, he became increasingly authoritarian. Rahman amended the constitution, giving himself more emergency powers (including the suspension of fundamental rights). The Bangladesh famine of 1974 also worsened the political situation.
