A great power is a
While some nations are widely considered to be great powers, there is no definitive list of them. Sometimes the status of great powers is formally recognized in conferences such as the
The term "great power" was first used to represent the most important powers in
There are no set or defined characteristics of a great power. These characteristics have often been treated as empirical, self-evident to the assessor. However, this approach has the disadvantage of subjectivity. As a result, there have been attempts to derive some common criteria and to treat these as essential elements of great power status. Danilovic (2002) highlights three central characteristics, which she terms as "power, spatial, and status dimensions," that distinguish major powers from other states. The following section ("Characteristics") is extracted from her discussion of these three dimensions, including all of the citations.
Early writings on the subject tended to judge states by the
As noted above, for many, power capabilities were the sole criterion. However, even under the more expansive tests, power retains a vital place.
This aspect has received mixed treatment, with some confusion as to the degree of power required. Writers have approached the concept of great power with differing conceptualizations of the world situation, from multi-polarity to overwhelming
This differed from earlier writers, notably from
All states have a geographic scope of interests, actions, or projected power. This is a crucial factor in distinguishing a great power from a regional power; by definition the scope of a
Other suggestions have been made that a great power should have the capacity to engage in extra-regional affairs and that a great power ought to be possessed of extra-regional interests, two propositions which are often closely connected.
Formal or informal acknowledgment of a nation's great power status has also been a criterion for being a great power. As political scientist
This approach restricts analysis to the epoch following the
A further option is to examine a state's willingness to act as a great power. As a nation will seldom declare that it is acting as such, this usually entails a retrospective examination of state conduct. As a result, this is of limited use in establishing the nature of contemporary powers, at least not without the exercise of subjective observation.
Other important criteria throughout history are that great powers should have enough influence to be included in discussions of contemporary political and diplomatic questions and exercise influence on the final outcome and resolution. Historically, when major political questions were addressed, several great powers met to discuss them. Before the era of groups like the United Nations, participants of such meetings were not officially named but rather were decided based on their great power status. These were conferences which settled important questions based on major historical events.
