Great power

A great power is a state that is recognized as having the ability to exert its influence on a global scale. Great powers characteristically possess military and economic strength, as well as diplomatic and soft power influence, which may cause small powers to consider the great powers' opinions before taking actions of their own. International relations theorists have posited that great power status can be characterized into power capabilities, spatial aspects, and status dimensions. Sometimes the status of great powers is formally recognized in conferences such as the Congress of Vienna or an international structure such as the United Nations Security Council.

The term "great power" was first used to represent the most important powers in Europe during the post-Napoleonic era. The "Great Powers" constituted the "Concert of Europe" and claimed the right to joint enforcement of the postwar treaties. The formalization of the division between small powers and great powers came about with the signing of the Treaty of Chaumont in 1814. Since then, the international balance of power has shifted numerous times, most dramatically during World War I and World War II. While some nations are widely considered to be great powers, there is no definitive list of them. Alternative terms for great powers are world powers or major powers.

Characteristics
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.

Early writings on the subject tended to judge states by the realist criterion, as expressed by the historian A. J. P. Taylor when he noted that "The test of a great power is the test of strength for war." Later writers have expanded this test, attempting to define power in terms of overall military, economic, and political capacity. Kenneth Waltz, the founder of the neorealist theory of international relations, uses a set of five criteria to determine great power: population and territory; resource endowment; economic capability; political stability and competence; and military strength. These expanded criteria can be divided into three heads: power capabilities, spatial aspects, and status.

Power dimensions
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 hegemony. In his essay, 'French Diplomacy in the Postwar Period', the French historian Jean-Baptiste Duroselle spoke of the concept of multi-polarity: "A Great power is one which is capable of preserving its own independence against any other single power."

This differed from earlier writers, notably from Leopold von Ranke, who clearly had a different idea of the world situation. In his essay 'The Great Powers', written in 1833, von Ranke wrote: "If one could establish as a definition of a Great power that it must be able to maintain itself against all others, even when they are united, then Frederick has raised Prussia to that position." These positions have been the subject of criticism.

Spatial dimension
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 regional power is restricted to its region. It has been suggested that a great power should be possessed of actual influence throughout the scope of the prevailing international system. Arnold J. Toynbee, for example, observes that "Great power may be defined as a political force exerting an effect co-extensive with the widest range of the society in which it operates. The Great powers of 1914 were 'world-powers' because Western society had recently become 'world-wide'."

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.

Status dimension
Formal or informal acknowledgment of a nation's great-power status has also been a criterion for being a great power. As political scientist George Modelski notes, "The status of Great power is sometimes confused with the condition of being powerful, The office, as it is known, did in fact evolve from the role played by the great military states in earlier periods ... But the Great power system institutionalizes the position of the powerful state in a web of rights and obligations."

This approach restricts analysis to the post-Congress of Vienna epoch; it being there that great powers were first formally recognized. In the absence of such a formal act of recognition it has been suggested that great power status can arise by implication, by judging the nature of a state's relations with other great powers.

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 political and diplomatic questions of the day, and have 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 were decided based on their great power status. These were conferences which settled important questions based on major historical events. This might mean deciding the political resolution of various geographical and nationalist claims following a major conflict, or other contexts.

There are several historical conferences and treaties which display this pattern, such as the Congress of Vienna, the Congress of Berlin, the discussions of the Treaty of Versailles which redrew the map of Europe, and the Treaty of Westphalia.

History
Different sets of great, or significant, powers have existed throughout history; however, the term "great power" has only been used in scholarly or diplomatic discourse since the Congress of Vienna in 1815. The Congress established the Concert of Europe as an attempt to preserve peace after the years of Napoleonic Wars.

Lord Castlereagh, the British Foreign Secretary, first used the term in its diplomatic context, in a letter sent on February 13, 1814: "It affords me great satisfaction to acquaint you that there is every prospect of the Congress terminating with a general accord and Guarantee between the Great powers of Europe, with a determination to support the arrangement agreed upon, and to turn the general influence and if necessary the general arms against the Power that shall first attempt to disturb the Continental peace."

The Congress of Vienna consisted of five main powers: the Austrian Empire, France, Prussia, Russia, and the United Kingdom. These five primary participants constituted the original great powers as we know the term today. Other powers, such as Spain, Portugal, and Sweden were consulted on certain specific issues, but they were not full participants. Hanover, Bavaria, and Württemberg were also consulted on issues relating to Germany.

Of the five original great powers recognised at the Congress of Vienna, only France and the United Kingdom have maintained that status continuously to the present day, although France was defeated in the Franco-Prussian War and occupied during World War II. After the Congress of Vienna, the British Empire emerged as the pre-eminent power, due to its navy and the extent of its territories, which signalled the beginning of the Pax Britannica and of The Great Game between Britain and Russia. The balance of power between the Great Powers became a major influence in European politics, prompting Otto von Bismarck to say "All politics reduces itself to this formula: try to be one of three, as long as the world is governed by the unstable equilibrium of five great powers."

Over time, the relative power of these five nations fluctuated, which by the dawn of the 20th century had served to create an entirely different balance of power. Some, such as the United Kingdom and Prussia (as part of the newly formed German state), experienced continued economic growth and political power. Others, such as Russia and Austria-Hungary, stagnated. At the same time, other states were emerging and expanding in power, largely through the process of industrialization. The foremost of these emerging powers were Japan after the Meiji Restoration and the United States after its civil war, both of which had been minor powers in 1815. By the dawn of the 20th century the balance of world power had changed substantially since the Congress of Vienna. The Eight-Nation Alliance was a belligerent alliance of eight nations against the Boxer Rebellion in China. It formed in 1900 and consisted of the five Congress powers plus Italy, Japan, and the United States, representing the great powers at the beginning of 20th century.

Great powers at war


Shifts of international power have most notably occurred through major conflicts. The conclusion of the Great War and the resulting treaties of Versailles, St-Germain, and Trianon witnessed the United Kingdom, France, Italy, Japan and the United States as the chief arbiters of the new world order. In the aftermath of World War I the German Empire was defeated, the Austria-Hungarian empire was divided into new, less powerful states and the Russian Empire fell to a revolution. During the Treaty of Versailles the "Big Three"—France, United Kingdom and the United States—held noticeably more power and influence on the proceedings and outcome of the treaty than Italy or Japan.

The victorious great powers also gained an acknowledgement of their status through permanent seats at the League of Nations Council, where they acted as a type of executive body directing the Assembly of the League. However, the Council began with only four permanent members—Great Britain, France, Italy, and Japan—because the United States, meant to be the fifth permanent member, left because the US Senate voted on 19 March 1920 against the ratification of the Treaty of Versailles, thus preventing American participation in the League.

When World War II started in 1939, it divided the world into two alliances—the Allies (the United Kingdom and France at first, followed in 1941 by the Soviet Union, the United States, and China); and the Axis powers consisting of Germany, Italy and Japan. The end of World War II saw the United States, United Kingdom, and Soviet Union emerge as the primary victors. The importance of the Republic of China and France was acknowledged by their inclusion, along with the other three, in the group of countries allotted permanent seats in the United Nations Security Council.

Since the end of the World Wars, the term "great power" has been joined by a number of other power classifications. Foremost among these is the concept of the superpower, used to describe those nations with overwhelming power and influence in the rest of the world. It was first coined in 1944 by William T.R. Fox and according to him, there were three superpowers: the British Empire, the United States, and the Soviet Union. But by the mid-1950s the British Empire lost its superpower status, leaving the United States and the Soviet Union as the world's superpowers. The term middle power has emerged for those nations which exercise a degree of global influence, but are insufficient to be decisive on international affairs. Regional powers are those whose influence is generally confined to their region of the world.

During the Cold War, the Asian power of Japan and the European powers of the United Kingdom, France, and West Germany rebuilt their economies. France and the United Kingdom maintained technologically advanced armed forces with power projection capabilities and maintain large defence budgets to this day. Yet, as the Cold War continued, authorities began to question if France and the United Kingdom could retain their long-held statuses as great powers. China, with the world's largest population, has slowly risen to great power status, with large growth in economic and military power in the post-war period. After 1949, the Republic of China began to lose its recognition as the sole legitimate government of China by the other great powers, in favour of the People's Republic of China. Subsequently, in 1971, it lost its permanent seat at the UN Security Council to the People's Republic of China.

Aftermath of the Cold War

China, France, Russia, the United Kingdom and the United States are referred to as great powers. These five nations are the only states to have permanent seats with veto power on the UN Security Council. They are also the recognized "Nuclear Weapons States" under the Nuclear Non-Proliferation Treaty, and have the five largest military expenditures in the world.

After the dissolution of the Soviet Union, its UN Security Council permanent seat was transferred to the Russian Federation in 1991, as its successor state. The newly formed Russian Federation emerged on the level of a great power, leaving the United States as the only remaining global superpower (although some support a multipolar world view).

However, there is no unanimous agreement among authorities as to the current status of these powers or what precisely defines a "great" power. Sources have at times referred to China, France, the United Kingdom, and Russia  as middle powers.

Japan and Germany are sometimes classified as middle powers. However, they are also included among the great powers,   due to their economic status (having the third and fourth largest economies respectively), despite their lack of permanent seats and veto power on the UN Security Council or strategic military reach.

Emerging powers
With continuing European integration, the European Union is increasingly being seen as a great power in its own right, with representation at the WTO and at G8 and G-20 summits. This is most notable in areas where the European Union has exclusive competence (i.e. economic affairs). It also reflects a non-traditional conception of Europe's world role as a global "civilian power", exercising collective influence in the functional spheres of trade and diplomacy, as an alternative to military dominance. The European Union is a supranational union and not a sovereign state, and has limited scope in the areas of foreign affairs and defense policy. These remain largely with the member states of the European Union, which include the three great powers of France, Germany and the United Kingdom (referred to as the "EU three").

Brazil and India are widely regarded as countries with the potential to be great powers. Academics, such as Zbigniew Brzezinski, Stephen P. Cohen and others regard India as a major or great power.

Permanent membership of the UN Security Council is widely regarded as being a central tenet of great power status in the modern world; Brazil, Germany, India and Japan form the G4 nations which support one another (and have varying degrees of support from the existing permanent members) in becoming permanent members. There are however few signs that reform of the Security Council will happen in the near future.

Hierarchy of Great powers
Acclaimed political scientist, geo-strategist, and former United States National Security Advisor, Zbigniew Brzezinski, appraised the current standing of the great powers in his book Strategic Vision: America & the Crisis of Global Power. In relation to great powers, he makes the following points:

""The United States is still preeminent but the legitimacy, effectiveness, and durability of its leadership is increasingly questioned worldwide because of the complexity of its internal and external challenges.... The European Union could compete to be the world’s number two power, but this would require a more robust political union, with a common foreign policy and a shared defense capability.... In contrast, China’s remarkable economic momentum, its capacity for decisive political decisions motivated by clearheaded and self centered national interest, its relative freedom from debilitating external commitments, and its steadily increasing military potential coupled with the worldwide expectation that soon it will challenge America’s premier global status justify ranking China just below the United States in the current international hierarchy....  A sequential ranking of other major powers beyond the top two would be imprecise at best. Any list, however, has to include Russia, Japan, and India, as well as the EU’s informal leaders: Great Britain, Germany, and France.""
