A series of bloody coups and counter-coups in the following three months culminated in the ascent to power of General Ziaur Rahman, who reinstated multi-party politics and founded the Bangladesh Nationalist Party (BNP). Zia's rule ended when he was himself assassinated in 1981 by elements of the junta military. Bangladesh's next major ruler was General Hossain Mohammad Ershad, who gained power in a bloodless coup in 1982 and ruled until 1990, when he was forced to resign under western donor pressure in a major shift in international policy after the end of communism when anti-communist dictators were no longer felt necessary. Since then, Bangladesh has reverted to a parliamentary democracy. Zia's widow, Khaleda Zia, led the Bangladesh Nationalist Party to parliamentary victory at the general election in 1991 and became the first female Prime Minister in Bangladesh's history and the second one in the Muslim world. However, the Bangladesh Awami League, headed by Sheikh Hasina, one of Mujib's surviving daughters, clinched power at the next election in 1996 but lost to the Bangladesh Nationalist Party again in 2001.
