The Netherlands remained neutral during World War I. This stance arose partly from a strict policy of neutrality in international affairs that started in 1830 with the secession of Belgium from the north. Dutch neutrality was not guaranteed by the major powers in Europe, nor was it a part of the Dutch constitution. The country's neutrality was based on the belief that its strategic position between the German Empire, German-occupied Belgium, and the British guaranteed its safety.[1]
The Royal Netherlands Army was mobilized throughout the conflict, as belligerents regularly attempted to intimidate the Netherlands and place demands on it. In addition to providing a credible deterrence, the army had to house refugees, guard internment camps for captured soldiers, and prevent smuggling. The government also restricted the free movement of people, monitored spies, and took other wartime measures.
