As a reaction to the bifurcation of Pakistan (due to the rise of secularist forces in East Pakistan) in 1971, Islamic political parties began to see an increase in popular support. In the 1970s, the populist and elected Prime minister Zulfikar Ali Bhutto caved in to a major demand of the Islamic parties by declaring the Ahmadiyya Community to be non-Muslims. Under the constitution of 1973, Bhutto also banned alcohol, gambling and night clubs.
