After the defeat of the RMS on Ambon by Indonesian forces in November 1950, the self-declared government withdrew to Seram, where an armed struggle continued on until December 1963. The government in exile moved to the Netherlands in 1966, following resistance leader and president Chris Soumokil's capture and execution by Indonesian authorities. The exiled government continues to exist, with John Wattilete as its incumbent president since April 2010. The Republic of South Maluku has been a member state of the Unrepresented Nations and Peoples Organization (UNPO) since 1991.
