What is sovereignty and why is it central to nation-states in the global system?

• A. Sovereignty means the supreme authority within a country’s borders; essential for self-determination and international legitimacy.
• B. Sovereignty means dominating neighboring states.
• C. Sovereignty has no relation to self-determination.
• D. Sovereignty is only about economic control.

Answer: (A)

Sovereignty is the supreme, legitimate authority a state has to govern itself within its borders and to shape its own laws and policies. That control over territory and population lets a country determine how it is run, enforce its rules, and conduct its foreign relations without outside interference. This authority underpins self-determination—the right of a people to decide their political status—and it gives the world a common understanding that a state is a recognized, equal actor in international law. Because other states acknowledge this sovereignty, a country can enter into treaties, join international organizations, and be protected by norms of non-interference. In the global system, sovereignty is central because it defines who can claim statehood, negotiate on equal terms, and pursue development on its own terms. It’s broader than just power or economics; it’s about legitimate authority, recognition, and the capacity to govern both domestically and internationally.
