The Revolutionary Government of the Republic of Indonesia officially declared its existence on the 15th of February 1958. Lieutenant Colonel Ahmad Hussein issued this proclamation after a five-day ultimatum expired.
Lieutenant Colonel Ahmad Husein took control of Central Sumatra and led the Dewan Banteng council to seize local government functions on the 20th of December 1956. This action marked the start of a series of bloodless coups across the outer islands.
Military operations claimed 7,146 lives on both sides according to Abdul Haris Nasution. Six thousand one hundred fifteen of these deaths occurred among PRRI forces while the rest were civilians killed in events such as the shooting under the Jam Gadang clock tower.
The United States shifted its backing toward Sukarno and the central government because the military balance swung swiftly in favor of Jakarta between March and May 1958. The Pope incident on the 18th of May 1958 signaled the end of the CIA's covert support program for the rebels.
Ahmad Husein officially surrendered along with around 24,500 followers on the 29th of May 1961. Mohammad Natsir became the last leader to surrender on the 28th of September 1961 following the amnesty granted through Presidential Decree No. 322 dated the 22nd of June 1961.
