Two years after his dismissal as Army Chief of Staff following the show of force known as the 17 October 1952 incident, General Abdul Haris Nasution established IPKI as an "army front organization" along with other military figures such as Gatot Soebroto and Azis Saleh, and with the support of the Yogyakarta sultanate. The party proposed a return to the spirit of the Proclamation of Independence and the 1945 Constitution as the way out of the political and economic problems that Indonesia had faced since independence. It also called for an end to corruption and for the "liberation of West Irian", still administered by the Dutch at the time.
