Sudisman
Sudisman (1920 – October 1968) was a general secretary of the Communist Party of Indonesia (PKI) and the only PKI leader to be put on trial following the 30 September Movement in 1965. He was sentenced to death and executed.
He was the fourth highest ranking member of the Communist Party of Indonesia's Politburo, and was the only one of the five senior leaders of PKI to be tried. All but one of the ten PKI politburo members were killed.
Sudisman tried to reorganize the PKI into an underground movement after other senior leaders were captured and summarily executed. He acted as the leader of the PKI for a short time before his arrest. He was finally arrested in December 1966.
