The political identity of the Pakistani Armed Forces, Pakistan's largest institution and one which controlled the government for over half the history of modern-day Pakistan and still does, is reliant on the connection to Pakistan's Imperial past. The Pakistan Muslim League's fortunes up till the 1970s were propelled by its legacy as the flagship of Pakistan's Independence Movement, and the core platform of the party today evokes that past, considering itself to be the guardian of Pakistan's freedom, democracy and unity as well as religion. Other parties have arisen, such as Pakistan Peoples Party, once advocating a leftist program and now more centrist.
