The Great Indonesia Unity Party (Indonesian: Partai Parsatuan Indonesia Raya, PIR) was an Indonesian political party established in 1948. It was founded by a group of dissenters who broke away from the Indonesian National Party (PNI) because of their dissatisfaction with the PNI's increasingly left-wing stance. Its chairman was Wongsonegoro, governor of Central Java. The party aimed to be based on neither religion like the Masjumi or a western political outlook (like the PNI). Initially known as the PNI-Merdeka (PNI-Independent) it subsequently changed its name to the Great Indonesia Unity Party.[1]
