In a world marked by growing interdependence and unprecedented transformations, understanding global politics requires tools that go beyond state-centric and territorial visions. This course offers a reflexive introduction to geopolitics as both a field of knowledge and a mode of power. It examines how actors (States, International Organizations, corporations, NGOs, private actors, etc.) project power, regulate global issues, and engage in cooperation or conflict across multiple scales (global, regional, national, local). Students will explore how geopolitical narratives, maps, and institutional practices contribute to shaping today’s complex world order. Combining theoretical frameworks from international relations, political geography, and sociology with empirical case studies, the course equips students with the analytical skills to interpret contemporary crises, conflicts, and spatial dynamics in global politics.
