This dissertation examines the evolving dynamics between sovereignty and integration in the European Union (EU), focusing on digital policies and their implications. The research delves into how the EU addresses the challenges of digital sovereignty and internet interdependence, all while aiming to enhance regional cohesion and stimulate economic growth. Drawing on theoretical frameworks like neo-functionalism, intergovernmentalism, and supranationalism, the study is focused on offering an in-depth perspective on the interaction between national and supranational governance structures. Through an analysis of key policy initiatives such as the European Interoperability Framework (EIF) and the Interoperable Europe Act, the dissertation illustrates the EU's goals of promoting integration and interconnectedness while upholding the sovereignty of its member states. The findings shed light on the complex balancing act undertaken by the EU, highlighting both tensions and synergies that shape its governance approach towards these crucial policy domains.
