"Jewish population before the war

Before 1940, the Netherlands, Belgium and France had been characterized by a parliamentary democracy and a liberal tradition for decades. Admittedly there was some antisemitism, often not openly expressed, but in these countries there had been no legal difference between Jewish and non-Jewish citizens for almost 150 years. The percentage of Jews of the total population did not differ very much and was low in all three countries: 0.75% of the French and Belgian population, and 1.5% of the Dutch population."
