Additionally, a Greater Netherlands state may include the annexation of the French Westhoek, Suriname, formerly Dutch-speaking areas of Germany and France, or even the ethnically Dutch and/or Afrikaans-speaking parts of South Africa.

[6] While Geyl—an outspoken anti-fascist—argued from a historical and cultural perspective, the fascist Verdinaso and Nazi movements built upon the idea of a Greater Netherlands during the 1930s and 1940s with a focus on ethnic nationalism, a concept still prominent among some on the far-right.

This label was popular until the Second World War, but its associations with collaboration (especially in Flanders) meant that modern supporters generally avoid using it.

[10] The Prince's Flag is sometimes used by both Orangist and Greater Netherlandic groups due to its use by supporters of William I of Orange during the Eighty Years' War, who led the revolt of the Low Countries against the Spanish.

'Waar Maas en Schelde vloeien' (also known as 'Het Lied der Vlamingen') is a popular Greater Netherlandic song written around this time by Peter Benoit and Emmaniel Hiel.

While their administration of Belgium was divided along linguistic lines in a policy similar to Flamenpolitik, the German Nazis did not seek to combine Flanders with the Netherlands.

In 2021, the leader of the Flemish Nationalist N-VA, Bart De Wever argued in Trends Talk on Kanaal Z that the next step after Belgian Confederalism should be a union of Flanders and the Netherlands,[24] which led to a resurgence in discussions on the topic.

[30] Although it hasn't been a major political issue in the Netherlands for quite some time, in 2007, a poll indicated that two-thirds of the Dutch population would welcome a union with Flanders.

[33] While the prevailing Dutch view on unification is it being a means of territorial expansion, the Flemish have expressed fears of being culturally assimilated into the larger and more populous Netherlands.
