Sovereignty is the supreme authority to govern — the claim that within a defined territory, a particular entity (the state, the monarch, the people) has the final word on political questions and is not subject to a higher external authority. It is a foundational concept of the modern international order and a frequent source of historical conflict.
State sovereignty and popular sovereignty
State sovereignty is the claim that states have supreme authority within their own territory and are not subject to interference from other states or from international institutions. The Westphalian system of international relations, established by the Treaty of Westphalia (1648), institutionalised this principle. It provides the framework within which decolonisation happened: nationalist movements demanded that their territories should govern themselves, free from external sovereignty.
Popular sovereignty is the claim that ultimate authority rests with the people rather than with a monarch, aristocracy, or other elite. It is the democratic principle underlying constitutions from the American Declaration of Independence onwards. The tension between state sovereignty (which protects governments from interference) and popular sovereignty (which grounds legitimacy in the people) runs through twentieth-century political history: when a government loses popular legitimacy, does it retain sovereignty?
How to use it in an answer
Sovereignty is relevant to questions about decolonisation, the Suez crisis, the Cold War, and the legitimacy of regimes. The argument that colonial populations had a right to self-determination rested on popular sovereignty — the claim that the people of India, Ghana, or Algeria, not the British or French state, were the ultimate sovereign authority over their own territories. Understanding the concept allows you to articulate these arguments precisely rather than relying on vague appeals to ‘rights’ or ‘independence’.
