As an implication of the ethnically and nationally diverse nature of Mediterranean polities, identification-driven boundary-making strategies bear considerable relevance for their political processes, both in the contemporary context and in the historical past. By utilizing a Discourse-Historical Approach (DHA), this study provides an interpretative exploration of Greek-Cypriot elite discursive framing strategies regarding Turkish-Cypriot and Greek-Cypriot ethno-national identity during the Cypriot Civil War (1963–1967). The available historical interpretations of this period lead us to expect an exclusionary strategy of boundary contraction to be more prevalent than the inclusionary one of boundary expansion in the discourse of Greek-Cypriot elites. Through an examination of a sample of primary textual sources, the analysis disconfirms such an expectation, as elite figures primarily constructed broader, inclusive frames of ethno-national identity during the civil war. The relative absence of boundary contraction and the prevalence of boundary expansion indicate the applicability of Wimmer’s (2008) universalist approach to ethnic boundary-making, in contrast to the expectations that are built by the Cyprus-specific historical evidence. This study thus lays the groundwork for future research to delineate the discursive framing strategies of elite figures in Cyprus and beyond the ethno-nationally divided island.
