Masyumi Party
In 1958, elements of the Indonesian military, with the support of the CIA, rebelled against the rule of President Sukarno. This attempted coup ended in failure. In February 1958, dissident military commanders in Central Sumatera (Colonel Ahmad Hussein) and North Sulawesi (Colonel Ventje Sumual) declared the Revolutionary Government of the Republic of Indonesia-Permesta Movement aimed at overthrowing the Sukarno regime. They were joined by many civilian politicians from the Masyumi Party, such as Sjafruddin Prawiranegara, who were opposed to the growing influence of the communist party, the Partai Komunis Indonesia or PKI. President Sukarno, in an address to the UN after the failed coup, denounced imperialism and vowed he was determined not to let a small corner of the world to make a play thing of Indonesia.
