In the social sciences, geopolitical theory is used in order to analyze states actions and commitments when it comes to foreign policy. This thesis develops a new understanding of geopolitical theory. Firstly, the development and application of geopolitical theory, from its foundations in the early twentieth century to contemporary geopolitical studies is discussed. Secondly a revised understanding of the variables integrated in the concept and how it can be operationalized as an analytical tool is presented and tested empirically.The critical assessment of the research field of geopolitical theory tells us that six different geopolitical perspectives have been considered the most influential (room, strategy, power projection, identity, affiliation and governance) when it comes to analyzing state action. This model is applied as an analytical tool and thus tested on a single case. The case study is an analysis of foreign policy discussions at the state level in Sweden. This has determined how the geopolitical perspectives function in relation to each other as well as presenting the need of new geopolitical perspectives, in order to understand a state’s foreign policies actions and commitments.The case study clearly shows the merits in using geopolitical perspectives and letting them interplay. The most important result, however, is that future studies needs to consider the connections between the six perspectives. The study has confirmed the need of an additional geopolitical perspective (ideology). Ideology as a seventh perspective addresses the issue of political intentions among a state’s representatives, and in that way helps to explain the dynamic connections between the other six geopolitical perspectives that influence states actions and commitments when it comes to foreign policy.
