Power transition theory is a theory about the nature of war, in relation to the power in international relations. [1] [2] [3] The theory was first published in 1958 by its creator, A.F.K. Organski, in his textbook, World Politics (1958).
According to Organski:
An even distribution of political, economic, and military capabilities between contending groups of states is likely to increase the probability of war; peace is preserved best when there is an imbalance of national capabilities between disadvantaged and advantaged nations; the aggressor will come from a small group of dissatisfied strong countries; and it is the weaker, rather than the stronger power that is most likely to be the aggressor.
Organski first described power transition theory. [4] : 22 According to Organski in his textbook, World Politics (1958):
An even distribution of political, economic, and military capabilities between contending groups of states is likely to increase the probability of war; peace is preserved best when there is an imbalance of national capabilities between disadvantaged and advantaged nations; the aggressor will come from a small group of dissatisfied strong countries; and it is the weaker, rather than the stronger power that is most likely to be the aggressor. [5]
Steve Chan summarizes the theory as "the danger of systemic war is greatest when a rising challenger catches up with or even overtakes a declining hegemon." [4] : 23 The underlying logic is that a rising power that is satisfied with the order of the international system has little incentive to challenge the status quo, while a dissatisfied rising power may wish to challenge the status quo. [4] : 23–24
Power transition theory interprets the international system as a hierarchical pyramid with the dominant power at the apex, then lesser great powers, then other medium and small states and dependences. [4] : 22
While Organski's hierarchy initially referred only to the entire international system, Douglas Lemke later expanded the hierarchy model to include regional hierarchies, arguing that each region contains its own dominant, great, and small powers. Thus regional hierarchies exist embedded into the larger international hierarchy. [6]
Power transition theory, a precursor of the long-cycle theory of hegemony, seeks to explain trends between warring states in the past 500 years. It detects a general trend: a nation achieves hegemonic power and then is challenged by a great power. This leads to a war which, in the past, has resulted a transition between two powers. Eugene R. Wittkopf explores past wars and their relation to power transition theory in his 1997 book World Politics: Trend and Transformation. He explains the interactions using George Modelski's Seapower Concentration Index. [2]
Power transition theory often cites the Peloponnesian War between Athens and Sparta and Thucydides' assertions that war was inevitable because of "the growth of the power of Athens, and the alarm which this inspired in Sparta" and "the strong do what they can and the weak suffer what they must." [4] : 21
Power transition theory uses European historical cases as its theoretical basis and for deriving its causal propositions. [4] : 31
In 1518, Portugal assumed a hegemonic position in world politics.[ citation needed ] However, as the Netherlands rose in power during the Dutch Golden Age of 1588 to 1672, a series of struggles led to the destruction of Portugal's power and a transition to Dutch hegemony. Dutch hegemony came into question from 1688 with the wars of Louis XIV of France, which resulted in what political scientists refer to as the "Britain I Cycle"; the Napoleonic Wars interrupted this cycle and questioned the hegemony Britain possessed. However, ultimately, Allies' victory in 1815 resulted in the maintenance of British power and the "Britain II Cycle". [2] This cycle ended with the World Wars of the first half of the 20th century. Wittkopf portrays the period of 1914–1945 as one of particular turbulence in which no power maintained hegemony, even after the 1919 Treaty of Versailles. [2] After the Second World War (1939–1945) the United States invested in a drastic increase in seapower concentration – and the U.S. and the Soviet Union became the world's first superpowers. [2]
A review by academics Xinru Ma and David C. Kang of articles first-tier journals found that the case most analyzed under power transition theory was the Anglo-German rivalry of the 20th century. [4] : 25 No articles within their review discussed an East Asian case from earlier than the late 19th century. [4] : 27–28
In general, hegemonic periods last approximately 60 to 90 years and conflicts which result in a period stabilization of power-distribution last approximately 20 years. [2] This can be explained through war-weariness and the tendency (although this was broken in the first half of the 20th century) for nations not to engage themselves in another conflict after being involved in a power transition. [2]
Power transitions play an important role in applications of the bargaining model of war where wars are more likely to break out and be severe in situations of uncertainty and of commitment problems. During power transitions, it is harder for actors to credibly commit to abide by any agreement, thus creating major commitment problems. [7] [8]
International relations scholars Randall Schweller and Xiaoyu Pu find that the challenger not only seeks to increase its material power but also to promote its own ideological and normative frameworks as alternatives to those propagated by the hegemon. [9]
Michael Beckley, writing in 2023, states that conflict between great powers can happen even when a power transition does not appear to be likely. He argues that rising powers have historically
"lashed out when they realized that they would not catch their rivals or achieve their grand ambitions—unless they took drastic action. These peaking power dynamics help explain some of the most consequential geopolitical events of the past 150 years, including the surge of U.S. imperialism in the late nineteenth century, the outbreak of World War II, and Russia's 2014 annexation of Crimea and intervention in eastern Ukraine." [10]
Publishing in 2024, Academics Xinru Ma and David C. Kang write that nearly all of the cases analyzed under power transition theory are post-1820s European cases. [4] : 6 They write that this approach creates a Eurocentric "blind spot" and overemphasizes the importance and generalizability of the European and Western historical experience. [4] : 6 They contend that this "has led to an overexpectation that power transitions are a principal cause for war and that the theory is universally applicable across time and space." [4] : 9
Academics Richard Ned Lebow and Benjamin Valentino write, "Power transition theorists have been surprisingly reluctant to engage historical cases in an effort to show that wars between great powers have actually resulted from the motives described by their theories." [4] : 31
Neorealism or structural realism is a theory of international relations that emphasizes the role of power politics in international relations, sees competition and conflict as enduring features and sees limited potential for cooperation. The anarchic state of the international system means that states cannot be certain of other states' intentions and their security, thus prompting them to engage in power politics.
Hegemony is the political, economic, and military predominance of one state over other states, either regional or global.
In international relations, power is defined in several different ways. Material definitions of state power emphasize economic and military power. Other definitions of power emphasize the ability to structure and constitute the nature of social relations between actors. Power is an attribute of particular actors in their interactions, as well as a social process that constitutes the social identities and capacities of actors.
A great power is a sovereign state that is recognized as having the ability and expertise 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 middle or 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.
Power politics is a theory of power in international relations which contends that distributions of power and national interests, or changes to those distributions, are fundamental causes of war and of system stability.
National power is defined as the sum of all resources available to a nation in the pursuit of national objectives. Assessing the national power of political entities was already a matter of relevance during the classical antiquity, the Middle Ages and the Renaissance and today. Classics Shang Yang, Guan Zhong and Chanakya, widely discussed the power of state. Many other classics, such as Mozi, Appian, Pliny the Elder, also concerned the subject. Herodotes described whence derives the power of Babylon. The considerations of Hannibal on the matter is found in Titus Livy.
Grand strategy or high strategy is a state's strategy of how means can be used to advance and achieve national interests in the long-term. Issues of grand strategy typically include the choice of military doctrine, force structure and alliances, as well as economic relations, diplomatic behavior, and methods to extract or mobilize resources.
In international relations, the concept of balancing derives from the balance of power theory, the most influential theory from the realist school of thought, which assumes that a formation of hegemony in a multistate system is unattainable since hegemony is perceived as a threat by other states, causing them to engage in balancing against a potential hegemon.
Hegemonic stability theory (HST) is a theory of international relations, rooted in research from the fields of political science, economics, and history. HST indicates that the international system is more likely to remain stable when a single state is the dominant world power, or hegemon. Thus, the end of hegemony diminishes the stability of the international system. As evidence for the stability of hegemony, proponents of HST frequently point to the Pax Britannica and Pax Americana, as well as the instability prior to World War I and the instability of the interwar period.
Collective security is a multi-lateral security arrangement between states in which each state in the institution accepts that an attack on one state is the concern of all and merits a collective response to threats by all. Collective security was a key principle underpinning the League of Nations and the United Nations. Collective security is more ambitious than systems of alliance security or collective defense in that it seeks to encompass the totality of states within a region or indeed globally.
In international relations, regional hegemony is the hegemony of one independently powerful state, known as the regional hegemon over other neighboring countries. The relationship between regional hegemons and the other states within their spheres of influence is analogous to the relationship between a global hegemon and the other states in the international system.
Realism, a school of thought in international relations theory, is a theoretical framework that views world politics as an enduring competition among self-interested states vying for power and positioning within an anarchic global system devoid of a centralized authority. It centers on states as rational primary actors navigating a system shaped by power politics, national interest, and a pursuit of security and self-preservation.
Polarity in international relations is any of the various ways in which power is distributed within the international system. It describes the nature of the international system at any given period of time. One generally distinguishes three types of systems: unipolarity, bipolarity, and multipolarity for three or more centers of power. The type of system is completely dependent on the distribution of power and influence of states in a region or globally.
Offensive realism is a structural theory in international relations that belongs to the neorealist school of thought and was put forward by the political scholar John Mearsheimer in response to defensive realism. Offensive realism holds that the anarchic nature of the international system is responsible for the promotion of aggressive state behavior in international politics. The theory fundamentally differs from defensive realism by depicting great powers as power-maximizing revisionists privileging buck-passing and self-promotion over balancing strategies in their consistent aim to dominate the international system. The theory brings important alternative contributions for the study and understanding of international relations but remains the subject of criticism.
The balance of power theory in international relations suggests that states may secure their survival by preventing any one state from gaining enough military power to dominate all others. If one state becomes much stronger, the theory predicts it will take advantage of its weaker neighbors, thereby driving them to unite in a defensive coalition. Some realists maintain that a balance-of-power system is more stable than one with a dominant state, as aggression is unprofitable when there is equilibrium of power between rival coalitions.
Defensive neorealism is a structural theory in international relations that is derived from the school of neorealism. The theory finds its foundation in the political scientist Kenneth Waltz's Theory of International Politics in which Waltz argues that the anarchical structure of the international system encourages states to maintain moderate and reserved policies to attain national security. In contrast, offensive realism assumes that states seek to maximize their power and influence to achieve security through domination and hegemony. Defensive neorealism asserts that aggressive expansion as promoted by offensive neorealists upsets the tendency of states to conform to the balance of power theory, thereby decreasing the primary objective of the state, which they argue to be the ensuring of its security. Defensive realism denies neither the reality of interstate conflict or that incentives for state expansion exist, but it contends that those incentives are sporadic, rather than endemic. Defensive neorealism points towards "structural modifiers," such as the security dilemma and geography, and elite beliefs and perceptions to explain the outbreak of conflict.
Randall L. Schweller is Professor of Political Science at the Ohio State University, where he has taught since 1994. He is a current member of the International Security editorial board and former Editor-in-Chief of the journal Security Studies.
The Tragedy of Great Power Politics is a book by the American scholar John Mearsheimer on the subject of international relations theory published by W.W. Norton & Company in 2001. Mearsheimer explains and argues for his theory of "offensive realism" by stating its key assumptions, evolution from early realist theory, and its predictive capability. An article adapted from the book had previously been published by Foreign Affairs.
Neoclassical realism is a theory of international relations and an approach to foreign policy analysis. Initially coined by Gideon Rose in a 1998 World Politics review article, it is a combination of classical realist and neorealist – particularly defensive realist – theories.
