Collaborationists included the
National Socialist Movement in the Netherlands (
Nationaal Socialistische Beweging "NSB"). The NSB declared that the monarchy was abolished and that the Netherlands should support Germany in the war. 20,000 to 25,000 Dutchmen served in the German Army and
Waffen SS.
The NSB's leader Anton Mussert attempted to convince Hitler that he should be leader of an independent Dutch state, Hitler denied this request and Reichskommissar Seyss-Inquart remained the ruler of the Netherlands though Mussert was allowed to take the title "Leader of the Dutch People" and allow the NSB to continue its political activities.
