Study reveals Dutch royal house's role in supporting slave trade

The Dutch royal house has been found to have helped keep the country’s slave trade alive, a new study revealed on Friday. The three‑year research, commissioned by King Willem‑Alexander and carried out by Leiden University, examined the period from 1600 to the present. It concluded that the House of Orange‑Nassau “actively supported Dutch colonialism for centuries, but only rarely determined colonial policy,” and that its members shared responsibility for the survival of the Dutch slave trade.

The study was launched as the Netherlands continues to grapple with the legacy of its colonial empire. The House of Orange has ruled the country since the late 1500s, first as stadtholders and later as monarchs. During that time the Dutch built vast overseas holdings in Southeast Asia and the Caribbean, including modern‑day Indonesia and Suriname. Historians and human‑rights experts said the royal family’s involvement was “wholehearted and without any real reservations,” noting that most rulers never objected to slavery.

Researchers found the royal family profited heavily from the colonial system, especially from trade in the Dutch East Indies, where profits in the 19th century would be about $650 million in today’s money. By contrast, the study showed the royals earned “almost nothing” from the slave trade itself. King Willem‑Alexander called the conclusions “painful and confronting,” saying they affect him even three generations removed. He reiterated the Netherlands’ ongoing struggle with discrimination and economic exploitation, and pointed to the 2022 state apology for transatlantic slavery and the 2023 royal apology that stopped short of reparations, opting instead for a €200 million fund for social initiatives.

The findings are likely to reignite debate over reparations and how the Netherlands addresses its past. The National Institute for the Dutch Slavery Past and Heritage praised the king for commissioning the study but urged that the new insights be used to foster awareness, dialogue, and corrective action. As the nation reflects on the research, pressure may grow for more substantial measures than the current fund, potentially reshaping how Dutch society confronts the enduring impacts of colonialism and slavery.
