Claim: On 25 April 1950, South Moluccan leaders, including former East Indonesia justice minister Christiaan Robbert Steven Soumokil, unilaterally declared the independent Republic of South Maluku (RMS) on Ambon and Seram, with Johanis Manuhutu becoming its first president; the declaration followed the breakdown of a December 1949 treaty between the Dutch and Indonesian governments that had stipulated autonomy for constituent states of a federation.

Claim: Indonesian forces defeated the RMS on Ambon in November 1950, after which the self-declared government withdrew to Seram, where armed resistance continued until 2 December 1963; Soumokil, who had become RMS president, was later captured and executed by Indonesian authorities.

Claim: Following Soumokil's capture and execution, RMS supporters proclaimed a government-in-exile in the Netherlands on 12 April 1966, with Johan Manusama becoming its first president-in-exile; the Dutch government neither supported nor recognized the RMS. Around this period, some 12,500 Moluccan soldiers of the former Royal Netherlands East Indies Army and their families were evacuated to the Netherlands, forming the basis of the present-day Moluccan diaspora there, estimated at approximately 70,000 people as of 2018.
