Quick Summary

The Partai Sosialis Indonesia (PSI) was a political party in Indonesia founded in 1948 by Sutan Sjahrir and Mohammad Hatta. It emerged from a split within the Indonesian Nationalist Party (PNI) and advocated for Western constitutional democracy. The PSI opposed the Communist Party of Indonesia (PKI).1

The party aimed to establish a socialist system in Indonesia, emphasizing democratic principles and opposing authoritarianism.

The PSI's legacy is tied to its role in the early years of Indonesian independence and its commitment to democratic socialism in a complex political landscape.1
