On 18 August 1941, the German occupation authorities set up the Polizeiliches Durchgangslager Amersfoort (Police Transit Camp Amersfoort).
The prisoners included resistance fighters, prisoners of war, people who were found in hiding, political prisoners, and Jews. In total, 35,219 people were imprisoned in
Amersfoort. The majority of prisoners were deported to German concentration camps, but many died in Amersfoort camp as a result of mistreatment or execution.
