The Macmillan Plan of 1958 epitomized Britain’s hegemonic strategy to impose a tripartite framework on Cyprus, masking imperialist interests behind the veneer of compromise. Rather than promoting self-determination, the plan institutionalized ethnic division through separate parliaments and dual citizenship, laying the groundwork for partition. It enabled Turkey’s formal return to Cypriot affairs after an 80-year absence, undermining internal sovereignty and violating popular will. Britain’s covert support for Turkey’s partitionist ambitions, coupled with the manipulation of intercommunal tensions, reveals a calculated effort to retain strategic control without direct governance. The plan’s rejection by all sides—Greek, Turkish, and Cypriot—underscored its illegitimacy and its alignment with hegemonic priorities rather than democratic principles.
