NSB and the Prinsenvlag

Dutch wartime collaboration — and why certain symbols still carry a charge

Part of: Tweede Wereldoorlog

What was the NSB?

The Nationaal-Socialistische Beweging (NSB) was the Dutch Nazi party, active from 1931 to 1945. During the German occupation of the Netherlands (1940–1945), the NSB collaborated with the occupiers. NSB members helped round up Jews, reported on resistance members, and administered occupied territories. About 100,000 Dutch people were members at the movement's peak.

After the war, NSB leaders were tried and executed. Members were purged from public life. The party is one of the most toxic labels in Dutch political history — calling someone an "NSB'er" is about as bad as it gets.

What is the Prinsenvlag?

The Prinsenvlag — literally "Prince's Flag" — is an orange-white-blue tricolour. It's the historical predecessor of the modern Dutch flag (which is red-white-blue). The orange stripe refers to the House of Orange-Nassau, the Dutch royal family.

The Prinsenvlag was adopted by the NSB as its flag during the occupation. Because of this, displaying it today carries an immediate connotation of fascism and collaboration — similar to how the Confederate flag functions in the United States. Most Dutch people see it and immediately think: Nazi sympathiser.

It occasionally appears at far-right demonstrations, sometimes claimed by people who say they're just showing Dutch heritage. Most observers don't buy it.

Why it keeps coming up

The Netherlands has a complicated relationship with its wartime history. The country had a high rate of Jewish deportation — about 75% of Dutch Jews were killed, higher than France or Belgium — and historians have debated why the Dutch administrative apparatus cooperated as efficiently as it did.

This history makes the Dutch particularly sensitive to the reappearance of fascist symbols. When the Prinsenvlag appears at an anti-asylum policy protest, it's not a neutral act. It places the protest in a lineage that most Dutch people find repugnant, even those who share concerns about immigration.

Recent appearances

  • May 2026: The Prinsenvlag was displayed at the anti-asylum "National Protest" in The Hague. Someone was also arrested in Leeuwarden for giving the Hitler salute at the same set of protests. Both incidents received significant coverage and were used by critics to argue that the far-right protest movement attracts genuinely extremist elements.
