Role in WW2
Main article: History of Liechtenstein § Liechtenstein during the World Wars
Shortly following the end of World War I, Liechtenstein concluded a customs and monetary agreement with neighboring Switzerland. In 1919, the close ties between the two nations were strengthened when Liechtenstein entrusted Switzerland with its external relations. At the outbreak of war, Prince Franz Josef II, who had ascended the throne only months before, promised to keep the principality out of the war and relied upon its close ties to Switzerland for its protection.
Attempts to sway the government did occur. After an attempted coup in March 1939, the National Socialist "German National Movement in Liechtenstein" was active but small. The organization, as well as any Nazi sympathies, virtually disappeared following the eruption of war.
