Pakistan is a multiparty democracy where several political parties bag seats in the National and Provincial assemblies. However, as an aftermath of the Fall of Dhaka in 1971, a two-party system was inculcated between the Peoples Party and Muslim League. There has also been a sharp rise in the popularity of centrist parties such that PML-Q and PTI. The Military establishment has played an influential role in the country's politics. From 1950s to 2000s, several coups were staged that overthrew democratic regimes. However, after the resignation of President Pervez Musharraf in 2008, a sharp line has been drawn between the Military and politics and Pakistan is moving closer to becoming a Liberal Democracy.
