Moluccan diaspora
As the result of the end of its occupation over the Dutch East Indies in the 1950s, the Netherlands government decided to transport around 12,000 Moluccan soldiers of the Royal Netherlands East Indies Army and their families to Europe, as they had fought on the Dutch side during the Indonesian National Revolution. They were then discharged on arrival, not allowed to work, given pocket money, and 'temporarily' housed in camps. The Dutch government never made any effort to help the Moluccans establish their Republik Maluku Selatan (RMS), which the Indonesian government refuses to recognise to this day. Although  the South Moluccan Republic was declared on 25 April 1950, this movement was defeated by the Indonesian government and the rest of the RMS followers left their homeland and formed a government in exile in the Netherlands in 1966. There were a number of actions performed by radicalised young Moluccans during the '70s in the Netherlands, including hijacking a train, taking hostages at De Punt in Groningen and at a school in Bovensmilde.
