This study examines the geopolitical transition and reshuffling of power-distribution in the Eastern Mediterranean and Middle East borderland region from 2014 to 2020. Using a framework derived from neo-realist international relations theory, it investigates the diplomatic and military alliances and rivalries that have led to the formation of competitive power blocs in the region. The research analyses 37 state and non-state actors involved in 194 distinct conflict dyads to identify patterns of geostrategic alliances and rivalries. The emergence of “paradoxical alliances” and "unorthodox rivalries" indicates that traditional divisions are insufficient for explaining the new geopolitical order. The main objective is to systematize our understanding of strategic power shifts and local realignments in the Eastern Mediterranean and examine how these affiliations and interdependencies have created a transnational context in a fluid geopolitical landscape. The study contends that the newly formed power blocs largely result from overlapping security contests between revisionist and status quo actors. In this context, distinguishing between conservative and revisionist actors is crucial for establishing a clear taxonomy. Conservative actors seek to maintain stability by preserving and consolidating the existing geopolitical status quo, sometimes by making minor updates. In contrast, revisionist actors advocate for radical changes in power relations at both national and regional levels. Changes in the distribution of power and perceptions of group influence motivate agent behaviour and define their actions.
