Origins & Early Life

The Madiun Affair (Indonesian: Peristiwa Madiun, lit. 'Madiun Event'), also known as the 1948 PKI Rebellion (Pemberontakan PKI 1948) or the PKI Madiun Rebellion (Pemberontakan PKI Madiun), was an armed conflict between the Indonesian government and the left-wing People's Democratic Front (FDR), during the Indonesian National Revolution. The conflict began on September 18, 1948, in Madiun, East Java, and ended three months later when most FDR leaders and members were detained and executed by TNI forces. Opinions regarding the trigger of the conflict vary. According to Kreutzer, the downfall of Amir Sjarifuddin's government in January 1948 was the origin of the Madiun Affair.

Career & Major Achievements

Before then, during the second half of 1947, Partai Sosialis was split into two factions: one faction was led by Sjarifuddin, and a smaller faction was led by Sutan Sjahrir. The latter group grew as Sjarifudin put a strong emphasis on its alignment with the Soviet Union and class struggle. Sjahrir believed that the Marxist doctrine of class struggle could not be applied in the Indonesian community as there was no such Indonesian bourgeoisie and that Indonesia should maintain a "positive neutrality" so that Indonesia could contribute to world peace. The party completely split soon after the establishment of Hatta's presidential cabinet. Sjarifuddin's premiership ended on January 28, 1948.

Enduring Legacy & Impact

Sjahrir, Dr. Leimena, and several political activists had earlier approached Hatta and requested him to become the next prime minister. Hatta agreed if he got the PNI's and Masjumi's support. Driven by the need to form a cabinet with national support (both right-wing and left-wing), Hatta offered Sjarifuddin's faction some posts in the cabinet. They declined Hatta's offer and demanded key positions, including Sjarifuddin's position as Minister of Defense (in the previous cabinet, Sjarifuddin had been both Prime Minister and Minister of Defense) in return for their support for Hatta's government. Negotiation failed, and on January 31, 1948, Hatta finally formed a cabinet without the Sajap Kiri (left-wing) parties.
