According to the National Freedom Research in 2006 held by the National Committee 4 and 5 Mai, it was said that during the Second World War in the Netherlands about five percent of the population was active in the resistance, five percent were actively involved with the Germans and the rest was not “wrong” but did not support the resistance either and continued on with their usual lives, in as far as that was possible. According to the Resistancemuseum Amsterdam, the Netherlands included 9 million inhabitants at the time. This means that the total number of estimated resistance members reaches 450.000 people.
Wikipedia: The Dutch resistance in the Second World War is the collective name for all persons and groups who resisted the German occupation of the Netherlands during the Second World War (1940-1945). The resistance, compared to other occupied countries, characterized by relatively few armed and violent resistance and a very successful movement of people going in to hiding, which led to a major resistance organization, the LO (National Organization for Assistance going into Hiding). Ultimately, according to the NIOD Institute for War, Holocaust and Genocide Studies 350.000 Dutch subjects went in to hiding (a record in occupied Europe), including 25.000 Jews.
