The Socialist Party of Indonesia was a socialist political party in Indonesia. It was founded at a meeting in Jogjakarta on 13 November 1945. The Defence Minister Amir Sjarifuddin was the chairman of the party. Parsi was largely made up by Amir Sjarifuddin's former colleagues from the wartime resistance struggle in East Java. Some of them originated in Gerindo, a leftwing, nationalist and pro-Sukarno group active before the war. There were also some persons, like Abdulmadjid, Moewaladi and Tamzil, who had lived in the Netherlands during the war, and taken part in the anti-fascist resistance struggle there. The primary objective of Parsi was the independence of Indonesia from colonial rule, which was to be followed by the construction of a socialist society.
