The Dutch royal family supported colonialism for centuries and benefited from it, according to an independent study presented to King Willem-Alexander on Friday.
Researchers examined the House of Orange-Nassau’s role from 1600 to the present. They found that earlier generations regarded Dutch colonial rule as legitimate, accepted violent campaigns against resistance, and, while slavery existed, did not use their position to oppose it. The study was carried out at Leiden University after the king called for an examination of his family’s history in 2022. (universiteitleiden.nl)
Support did not always mean control
The Leiden University account of the findings makes an important distinction: members of the royal house supported colonialism, but usually did not set colonial policy themselves. During the Dutch Republic, trading companies and other governing bodies held much of that power.
King Willem I was a major exception. In the nineteenth century, he exercised direct authority over colonial administration and helped establish a trading company that profited from the system in the Dutch East Indies, now Indonesia. Later constitutional changes reduced the monarchy’s political influence, although the family continued to lend colonial rule its public standing. (universiteitleiden.nl)
The researchers also found substantial financial gains. They estimated that the family’s noneteenth-century colonial income was in the order of €500 million in today’s money, largely connected to trade in the East Indies. That figure should not be presented as money earned from the transatlantic slave trade: the study found that the family gained almost nothing directly from that trade, despite attempts to profit from it.

King accepts the findings
In his response to the study, Willem-Alexander acknowledged that earlier rulers had actively supported colonialism and slavery, including the suppression of resistance. He said their actions helped those systems continue and described the conclusions as confronting.
The king said he accepted the research and viewed it as a reason to continue work towards recognition and reconciliation. He had previously apologised for the Netherlands’ role in slavery in 2023. (koninklijkhuis.nl, reuters.com)
Questions over what follows
The findings are likely to add to discussions about how the Netherlands addresses its colonial past. Dutch rule extended across parts of Southeast Asia and the Caribbean, including present-day Indonesia and Suriname. The consequences of that history remain significant to communities with ties to those places. (universiteitleiden.nl, reuters.com)
The Netherlands’ National Institute for the Dutch Slavery Past and Heritage welcomed the research but called for its findings to inform education and further discussion about responsibility and reparatory justice. The study establishes a fuller account of the royal house’s role; it does not itself announce a new reparations policy. (reuters.com)
