The Free Government of the Republic of Indonesia, or also known as PRIM, is hastily-formed coalition of anti-Sukarno dissidents that seek to end Japanese rule in Indonesia, thus starting the Indonesian Civil War.
It is a very diverse coalition of liberals, islamists, communists and generals, all opposed to Sukarno and his pro-Japanese government.
During the Indonesian civil war, they will receive support from the OFN, although they are careful to not become a proxy of said alliance.
