The 1999 military takeover in Pakistan was a bloodless coup d'état initiated by the military staff at the Joint Staff HQ working under the Chairman of the Joint Chiefs of Staff Committee and Chief of Army Staff General Pervez Musharraf. The instigators seized control of the civilian government of the popularly elected Prime Minister Nawaz Sharif on 12 October 1999. On 14 October, General Musharraf, acting as the country's Chief Executive, issued a controversial provisional order that suspended the Constitution of Pakistan.
