Legitimization Of The European Union’s Supranational Political Power In The Perspective Of Selected Theories Of European Integration

The aim of this paper is to seek a theoretical framework for explaining the sources of legitimacy of EU political power. The research problem concerns the establishing of the sources of legitimacy of the EU political system, depending on the implemented theories of European integration. The research process uses selected theories of European integration: intergovernmental theory, neo-functionalism and constructivism, which point to diverse sources of legitimacy of supranational political power. These include: the will and interests of sovereign states, the high efficiency and effectiveness of supranational political power in achieving the goals of various interest groups, and social norms and values. The analysis carried out enabled a positive verification of the research hypothesis on the diverse origins of the legitimacy of EU supranational power, justified within the framework of selected theories of European integration.
