Raymond Westerling (31 August 1919 – 26 November 1987), nicknamed the Turk, was a Dutch military officer of the KNIL (Royal Netherlands East Indies Army). He waged a massacre in Sulawesi during the Indonesian National Revolution after World War II. He was also responsible for a coup attempt against the Indonesian government in January 1950, a month after the official transfer of sovereignty. Both actions were denounced as war crimes by the Indonesian authorities.
