Power in international relations is defined in several different ways.
Political scientists,
historians, and practitioners of
international relations (
diplomats) have used the following concepts of
political powerModern discourse generally speaks in terms of state power, indicating both economic and military power. Those states that have significant amounts of power within the international system are referred to as middle powers, regional powers, great powers, superpowers, or hyperpowers, although there is no commonly accepted standard for what defines a powerful state.
Entities other than states can also acquire and wield power in international relations. Such entities can include multilateral international organizations, military alliance organizations (e.g. NATO), multinational corporations, non-governmental organizations, or other institutions such as the Roman Catholic Church, Wal-Mart[1], or the Hanseatic League.
Primary usage of "power" as a goal in international relations belongs to political theorists, such as Niccolò Machiavelli and Hans Morgenthau. Especially among Classical Realist thinkers, power is an inherent goal of mankind and of states. Economic growth, military growth, cultural spread etc. can all be considered as working towards the ultimate goal of international power.
