In the last four decades, the Strategic Triangle concept has established itself as an eclectic theoretical framework in the research domain of triangular analysis. As international politics has evolved, the literature on Strategic Triangle has followed suit. Specifically, it appears that scholars have succeeded in transcending beyond the ‘traditional’ regional setting and conceptualisation by testing existing theoretical assumptions, developing new models and offering new insights into the dynamics of triangular relationships. Against this background, this contribution primarily aims to provide a state-of-the-art, comprehensive overview of the scholarly literature on Strategic Triangles. This article also seeks to illustrate the existing room for further engagement and analysis of triangular relationships by offering concrete recommendations on how researchers could further develop the Strategic Triangle concept.
