Despite being neutral, the Netherlands in World War II was invaded by Nazi Germany on 10 May 1940, under orders of Adolf Hitler. On 14 May 1940, one day after the bombing of Rotterdam, the Dutch forces surrendered. The Dutch government and the royal family saved themselves by going to London. Princess Juliana and her children moved on to Canada for additional safety.
The Netherlands was placed under German occupation, which endured in some areas until the German surrender in May 1945. Active resistance was carried out by a minority, which grew in the course of the occupation. The occupiers deported the majority of the country's Jews to Nazi concentration camps.
