The term superpower came into wide use during the Cold War to describe the United States and the Soviet Union. It generally refers to a state with global reach in military, economic, and political influence.
Analysts debate which factors matter most: military capability, economic size, technology, alliances, soft power, or the ability to shape rules. Few countries lead in every category.
Rather than a fixed label, the idea is useful for comparing how states project influence and where their limits are.
