This thesis intended to examine how the actions of Sweden, following the 2014 Russian annexation of Crimea, fit within the international relations theoretical perspective of pragmatic idealism, focusing on the actions of Sweden's foreign policy that impacted its neutrality policy. This thesis is built upon the pragmatic idealism theoretical perspective of international relations, and attempted to address how this perspective accounted for, or failed to account for the actions of Sweden in the face of the escalating Russian threat. The analysis herein is grounded in case study methodology. First, the thesis examined how Sweden-Russia relations evolved in the wake of the Russian invasion of Ukraine. Second, the thesis examined how Sweden-NATO relations changed after the 2014-15 annexation of Crimea by Russia. In both cases, the paper analysed how the evolution of these relationships affected Sweden's neutrality, and how the evolution was consistent or not consistent with the “pragmatic” and “idealist” dimensions of the theoretical perspective of pragmatic idealism. The culmination of this paper drew an inference of the applicability of the perspective of pragmatic idealism to Sweden's application of neutrality to international relations. It concluded that Sweden's neutrality both prior to and following the invasion, as well as its subsequent actions, were in line with the theoretical perspective of pragmatic idealism.
