Situated at the intersection of energy politics and critical geopolitics, this article traces the evolution of the notion of energy transit as a constitutive aspect of Turkey’s foreign policy identity. By deploying process tracing and content analysis methods to analyze primary sources such as government reports, official statements, and newspaper articles, this article will explain how the image of Turkey as an energy transit country has been reproduced and how this particular aspect of Turkey’s identity shapes its foreign policy. It will be shown that Turkey’s self-perception as an energy transit country has had a distinct causal impact on how it relates to other powers, including the US, the EU and Russia. Simultaneously, the way Turkish policy makers imagined the country’s role as a energy corridor has been shaped by the geopolitical milieu, ranging from the post-Cold War shifts in spheres of influence to contemporary post-Arab spring security environment.
