This thesis investigates the role nonpermanent members have on the United Nations Security Council (UNSC). This as the contemporary scholarly debate on the UNSC tends to exclude the nonpermanent members in the study of the only international institution that can bind all UN members under its decisions. Building on the slim literature existing on why states seek the nonpermanent seats, this thesis uses the case of Sweden in order to investigate whether Sweden has met its objectives during its first year on the council. This case also contributes to a broader question of the potential influence nonpermanent members can have on the council. The results of this thesis are in line with the research it is building on, inherited from a liberal strand of international relations, that Sweden has influenced outcomes in line with its objectives and that nonpermanent members can influence the council in terms of resolutions, making them relevant to study in research concerning the UNSC. It also provides additional knowledge to the existing research it is building on by expanding the scope in how nonpermanent members can influence the council, which can be used in future studies.
