The Russian navy was suspicious of Swedish neutrality in 1914, as Sweden had been arming itself for many years, and almost unwittingly dragged the country into the war. Russia was seen as the main threat to Sweden, but Germany and Britain were also perceived as potential aggressors. The navy bore the main burden of protecting Sweden’s neutrality during the following years, and also played a major role during the Swedish expedition to the Åland Islands in 1918. However, Sweden failed to acquire Åland after the war, and eventually became disappointed in the League of Nations and collective security.
