Darul Islam rebels

The Darul Islam rebels under Kartosuwirjo in West Java refused to acknowledge Sukarno's authority and declared an NII (Negara Islam Indonesia - Islamic State of Indonesia) in August 1949. Rebellions in support of Darul Islam also broke out in South Sulawesi in 1951, and in Aceh in 1953. Meanwhile, pro-federalism members of the disbanded KNIL launched failed rebellion in Bandung (APRA rebellion of 1950), in Makassar in 1950, and Ambon (Republic of South Maluku revolt of 1950).
