After independence, Bangladesh adopted a secular democracy under its new constitution in 1972. Awami League premier Sheikh Mujibur Rahman became the country's strongman and implemented many socialist policies. A one party state was enacted in 1975. Sheikh Mujibur Rahman was assassinated later that year during a military coup that ushered in sixteen years of military dictatorships and presidential governments. The liberation war commander Ziaur Rahman emerged as Bangladesh's leader in the late 1970s. He reoriented the country's foreign policy towards the West and restored free markets and the multiparty polity. President Zia was assassinated in 1981 during a failed military coup. He was eventually succeeded by his army chief Hussain Muhammad Ershad. Lasting for nine years, Ershad's rule witnessed continued pro-free market reforms and the devolution of some authority to local government. The South Asian Association for Regional Cooperation (SAARC) was founded in Dhaka in 1985. The Jatiya Party government made Islam the state religion in 1988.
