ENLithuania is a small state by objective features (population, territory, GDP) and subjective ones (geopolitical position, resilience from external security threats, national identity). The goal of this research is to define the main roles of Lithuania, which are relevant to the Lithuanian foreign policy decision-making process nowadays. Those roles are the structure for Lithuania’s new President Gitanas Nausėda. While during his presidency he will have the possibility to modify them, for now for the roles formed and enacted over the last ten years serve as the limits of the change of the policy in the Euro-Atlantic area. The main assumption regarding the roles of Lithuania in the Euro-Atlantic area is that policymakers emphasize the smallness of the state. Accordingly, being a small state is translated to a set of expected and appropriate behavior. Therefore, the classical definition of smallness suggests that Lithuania’s roles should include the strategies of hiding and appeal to democratic values. In order to deny or confirm the assumptions, the research includes the definition of small states, an analysis of small state foreign policy strategies, the main thesis of the Role theory, the theoretical basis of subjective smallness concept, and discussion of Lithuania’s roles in the Euro-Atlantic area, using an interpretive methodology of Social constructivism. Keywords: small state, Lithuania, role, Social constructivism, foreign policy. [From the publication]
