- Transit agreement with Germany: After Germany invaded Denmark and Norway on 9 April, Sweden found itself surrounded. In June Sweden signed a transit agreement permitting German goods and troops to pass through Swedish territory between Norway and Finland.
- Breaking the Geheimschreiber cipher: Mathematician Arne Beurling single-handedly broke Germany's Geheimschreiber teleprinter cipher, giving Swedish military intelligence advance knowledge of German operations for years — one of WWII's greatest codebreaking feats.
- Home Guard established: Sweden formed the Hemvärnet (Home Guard) in 1940 as a volunteer local defence force, part of a broader mobilisation to resist potential invasion from any direction.
Events in this year
1939-11-30 Swedish Response to the Finnish Winter War 1939-1940 When the Soviet Union invaded Finland on 30 November 1939, Sweden declared itself non-belligerent rather than strictly neutral and supplied massive financial aid, food, aircraft, and ammunition to the Finnish side. Approximately 8,000 Swedish volunteers fought in the Svenska frivilligkåren. Foreign minister Rickard Sandler resigned over the cabinet's refusal to authorise stronger involvement and was replaced by Christian Günther — the first serious doctrinal split of the wartime samlingsregering. Foreign policy 1939-12-13 1939 Formation of the National Unity Government After the German invasion of Poland and the Soviet attack on Finland in autumn 1939, Per Albin Hansson dissolved his red-green coalition and formed a National Unity Government — the samlingsregering — that took office on 13 December 1939 and governed Sweden until the end of World War II. The cabinet included all four major Riksdag parties but excluded the Communists; its mission was strict neutrality, wartime supply management, and rapid military rearmament. Crisis 1940 1940 Finnkampen becomes a three-nation match with Germany The 1940 Finnkampen was held at Helsinki Olympic Stadium with Germany admitted as a third participant, turning a classic Nordic athletics match into a wartime neutrality episode. Sports 1939-1945 Beredskapstiden and Everyday Wartime Life 1939-1945 Sweden avoided combat in the Second World War, but beredskapstiden reshaped daily life through rationing, shortages, preparedness routines, and a public culture of crisis discipline.
