Bersiap is the name given by the Dutch to an extremely violent and chaotic phase in Dutch and Indonesian history, more specific of the Indonesian National Revolution, following the end of World War II and was most violent between about October 1945 and early 1946. 'Bersiap' and 'siap' are Malay for 'get ready' or 'be prepared'. These were the battle cries of Indonesian (para)military organizations and gangs, which almost immediately after the end of the Japanese occupation sowed death and destruction, especially among non-Indonesians, but also among natives suspected of "collaboration" with the Dutch authorities.
