Following the defeat of Allied forces in the Netherlands in 1940, and its occupation by Nazi Germany, Hilversum became the headquarters of the German Army ("Heer") in the Netherlands. On February 25 and 26, 1941, most of Hilversum's factories striked against the start of the Holocaust in the so called February strike (Amsterdam Docker's Strike). Some 10,000 people took part. There is a yearly remembrance service since 2015. The Holocaust was the reason for 2,000 Hilversum Jews to lose their lives. The community has never recovered fully. Some 50 Hilversummers were awarded the title of Righteous among the nations from Yad Vashem. Viktor Kugeler, one of Anne Frank's helper, was one of them.
