Sweden maintained its policy of neutrality during World War II. When the war began on September 1, 1939, the fate of Sweden was unclear. But by a combination of its geopolitical location in the Scandinavian Peninsula, realpolitik maneuvering during an unpredictable course of events, and a dedicated military build-up after 1942, Sweden kept its official neutrality status throughout the war.
