The Revolutionary Government of the Republic of Indonesia (Indonesian: Pemerintah Revolusioner Republik Indonesia/PRRI) was a rebel movement led by army officers of the Indonesian Army. The movement was started when a clash of few military factions inside the newly formed Indonesian Army backgrounded by the political rivalry began to demand of a new law on local autonomy all over the country. After their demands were nor met they began to rebel against the government. The rebellion included:
- Dewan Banteng in Central Sumatra which on 20 December 1956 under the leadership of Lieutenant Colonel Ahmad Husein (commander of the 4th regiment of the Territorial Army in Sumatra) began to take over the local government of Central Sumatra.
- Dewan Gajah in East Sumatra under Colonel Mauluddin Simbolon (Supreme Commander of the Territorial Army in Sumatra) which on 22 December on the same year began to take over the government of East Sumatra and cut all realation with the government.
- Dewan Garuda in South Sumatra which on 15 January 1957 under Lieutenant Colonel Barlian takeover the local government of South Sumatra.
In 15 February 1958 Lieutenant Colonel Ahmad Hussein declared the existence of PRRI. The Government in Jakarta immediately sent the army to destroy the rebellion and dishonorably discharged the three colonels. Army chief of staff Nasution Army immediately announced that the territorial army would be placed under his command. In short most of the areas were easily recaptured by the army, and most of the rebels' weapons were retrieved in good condition by the army.
The U.S government, which supported the rebels, started to withdraw their forces immediately after one of their fighter planes was shot down and its pilot Allen Pope was shot over Ambon.
