Sukarno founded the Indonesian Communist Party and worked with the Japanese during WWII. When the war ended, he declared himself president of an independent Indonesia. The Dutch returned to reclaim the country, leading to the war of independence and a civil war.
Following the KPK, another institution was planned to consolidate the democracy of Indonesia called the Commission for Truth and Conciliation, but its creation was prevented by supporters of Suharto. The former president had conducted an extremist campaign against the Communist Party in Indonesia, killing five hundred thousand people, mostly artists.
