Theories of International Politics are frameworks that help explain how countries interact on the global stage. Key theories include Realism, which focuses on power and national interest, and Liberalism, which emphasizes cooperation and international institutions. These theories provide insights into the behavior of states and the dynamics of international relations. Another important theory is Constructivism, which highlights the role of ideas, beliefs, and identities in shaping international politics. Each theory offers different perspectives on issues like conflict, diplomacy, and global governance, helping scholars and policymakers understand complex international phenomena.
