King Willem-Alexander will receive the results in Leiden on Friday of an independent study into the role of the House of Orange-Nassau in the Netherlands’ colonial history. The substantive conclusions will be explained during the presentation; before that event, they were not yet fully public.
The handover will take place in the Academy Building of Leiden University. The study began in 2022 at the king’s initiative and was carried out by a research team led by historian Gert Oostindie. According to the Royal House, the research group was granted access to, among other things, the Royal House Archives.
The project covers the period from 1600 through to 2025. Five books will be published on Friday, including a biographical work on the Orange-Nassau family, thematic volumes on colonial power, profit and prestige, and a book for general readers entitled Orange and the Colonies, 1600-2025.
The study’s independence is part of its design. The Royal House says the committee independently formulated the brief, assembled the research group and supervised the study. The researchers worked according to the usual rules of academic integrity and independence.
The central question is not only what personal role individual members of the House played, but also how the monarchy was connected to colonial power formation, governance, trade and prestige. NOS summarises the study around the question of whether the significance of the Orange-Nassau family was primarily symbolic or also directly connected to expansion, slavery and exploitation.
The timing makes the presentation politically and socially relevant. In recent years, Willem-Alexander has spoken several times about difficult parts of Dutch history, including the violence during Indonesia’s struggle for independence and the history of slavery. The new study could provide a basis for further discussions about responsibility, remembrance and the role of the monarchy.
The receipt of the books is not the end of the debate. Historians will be able to discuss the arguments and sources, while affected communities and descendants will focus particularly on how the findings are acknowledged. The question also remains what consequences the study will have for education, heritage and the public role of the royal family.
Because the factual results will only be presented on Friday, we are not anticipating the committee’s conclusions. What is certain at this stage concerns the brief, the research period, the independent design and the presentation; the substantive assessment of the colonial role must follow from the publications themselves.
