Exploring Dutch History: Nazi Collaboration Records Now Accessible

Genealogists and historians can now explore the names of over 425,000 individuals involved in investigations for collaboration with Nazi Germany, thanks to a newly launched Dutch database.

What Is the New Dutch Database on Nazi Collaboration?

In January 2025, the Dutch National Archives launched an online database accessible at oorlogvoorderechter.nl. This resource lists the names of individuals in the Netherlands who were investigated for collaboration with Nazi Germany during World War II. The database includes:

1. Over 425,000 Names: Including members of the German armed forces and the Dutch National Socialist Movement (NSB).
2. Investigation Details: Indicates whether an investigation was opened and provides references to the physical files held at the National Archives in The Hague.
3. Limited Online Details: Full case files are not published online to protect privacy and can only be consulted in person at the archives.

Why Is This Database Significant for Genealogists?

The database offers an unparalleled opportunity to uncover family histories and understand the complex legacy of World War II in the Netherlands. For genealogists, this resource can:

• Reveal Hidden Family Connections: Descendants can learn whether their relatives were investigated for collaboration and uncover the circumstances surrounding these cases.
• Contextualize Historical Events: The database sheds light on the broader involvement of Dutch society during the war.
• Support Victims’ Descendants: Families of victims can gain a deeper understanding of the impact of Nazi collaboration in their communities.

However, it is important to note that approximately 329,000 of the 425,000 listed cases did not lead to prosecutions, making consultation of the full records essential for accurate context.

How to Access These Records

1. Search the Online Database: Start by visiting oorlogvoorderechter.nl and searching for your ancestor’s name.
2. Locate File References: Each entry provides a reference to the physical file held at the National Archives.
3. Visit the National Archives: Full files are accessible on-site in The Hague. Note that photography is not allowed, and you may need to take detailed notes.
4. Use GenealogyDirect: If you cannot visit the archives in person, GenealogyDirect researchers can retrieve these records for you.

Why Consultation of Original Files Matters

The database provides an overview but lacks the depth found in the original documents. Full records may include:

• Names and statements of witnesses.
• Detailed descriptions of alleged activities.
• Contextual evidence that could exonerate or incriminate individuals.

Consulting these files allows for a nuanced understanding of individual cases and ensures accuracy in interpreting family histories.

The Broader Context of Nazi Collaboration Records

The Netherlands’ creation of this centralized database marks a significant step in acknowledging the country’s wartime history. Approximately 75% of Dutch Jews were exterminated during the Holocaust, and the role of local collaborators has long been a sensitive topic. These records offer a chance to confront and understand this difficult history.

In comparison, France lacks a centralized database on Nazi collaboration. French records are scattered across national, military, and departmental archives, making research more complex. GenealogyDirect can assist French researchers in navigating these disparate sources to locate relevant files.
