 Arendt and Blücher married on 16 January 1940, shortly after their respective divorces were finalized.On 5 May 1940, in anticipation of the German invasion of France and the Low Countries that month, the Gouverneur général of Paris issued a proclamation ordering all "enemy aliens" between 17 and 55 who had come from Germany (predominantly Jews) to report separately for internment.The women were gathered together in the Vélodrome d'Hiver on 15 May, so Hannah Arendt's mother, being over 55, was allowed to stay in Paris.
