Geopolitics and international relations explores how power and influence manifest themselves globally, shaped by historical, economic and cultural forces. This discipline examines power structures and the evolution of great powers in the modern era and their impact on the global balance. Key themes include the analysis of spheres of influence, dominant ideologies, imperialism, and conflict dynamics leading to states of tension and war. It also discusses geostrategic zones and how they contribute to power relations. Europe is a case study in the trends of continental integration and fragmentation, illustrating the complexity of international relations. In this context, international organizations play a key role in conflict management, promoting global cooperation and stability. Thus, the discipline provides a deep understanding of the mechanisms through which states interact and influence the world order.
