This chapter examines the European Union’s (EU) evolving impact on the relationship between Türkiye and Libya, highlighting a significant gap in existing literature regarding this dimension. While the EU, with its unique geopolitical and normative framework, is primarily a regional organization, its influence has grown progressively since its inception after World War II, transforming from an economic community into a supranational entity with broad political and legal competences. The chapter traces the EU’s institutional development and successive enlargements, noting the complexities and controversies that accompanied deeper integration. Importantly, it distinguishes between the EU’s collective role and the autonomous actions of individual member states, especially during periods such as Libya’s independence, when the EU’s direct influence was minimal. The analysis emphasizes that the EU’s impact on Turkish-Libyan relations has remained largely diplomatic and procedural, rather than transformative, due to persistent contradictions between the EU’s theoretical objectives and its practical capacities. The chapter concludes by addressing the European Community’s role during the Cyprus Crisis.
