The concept of sovereignty in international relations refers to the supreme authority of a state over its territory and the ability to govern itself without external interference. Sovereignty encompasses both legal and political dimensions, ensuring that a state can make its own laws, policies, and decisions. It is a defining feature of the Westphalian state system, which emphasizes the importance of territorial integrity and the recognition of borders between states. Sovereignty is challenged in today's interconnected world by issues such as globalization, international law, and humanitarian intervention, which can sometimes prioritize global interests over national sovereignty.
