- Balance of power in international relations
international relations, a balance of power exists when there is parity or stability between competing forces. As a term in international lawfor a 'just equilibrium' between the members of the family of nations, it expresses the doctrineintended to prevent any one nation from becoming sufficiently strong so as to enable it to enforce its will upon the rest.
"BoP" is a central concept in neorealist theory. Within a balance of power system, a
statemay choose to engage in either balancingor bandwagoningbehavior. In a time of war, the decision to balance or to bandwagon may well determine the survival of the state.
A doctrine of equilibrium
principleinvolved in a balancing of political power, as David Humepointed out in his "Essay on the Balance of Power", is as old as history, and was perfectly familiar to the ancients both as political theorists and as practical statesmen. In its essence it is no more than a precept of commonsense, born of experienceand the instinctof self-preservation; for, as Polybiusvery clearly puts it (lib. i. cap. 83):"Nor is such a principle to be despised, nor should so great a power be allowed to any one, as to make it impossible for you afterwards to dispute with him on equal terms, concerning your manifest rights."
As Professor L. Oppenheim ("Internal. Law", i. 73) justly points out, an equilibrium between the various powers which form the family of nations is, in fact, essential to the very existence of any
international law. In the absence of any central authority, the only sanction behind the codeof rules established by custom or defined in treaties, known as 'international law', is the capacity of the powers to hold each other in check. If this system fails, nothing prevents any state sufficiently powerful from ignoring the lawand acting solely according to its convenience and its interests.
Preserving the balance of power as a conscious goal of foreign policy, though certainly known in the ancient world, resurfaced in post-medieval Europe among the Italian city states in the 15th century.
Francesco Sforza, Duke of Milan, was the first ruler to actively pursue such a policy, though historians have generally (and incorrectly) attributed the innovation to the Medici rulers of Florence whose praises were sung by the well-known Florentine writers Niccolò Machiavelliand Francesco Guicciardini.
Universalism, which was the dominant direction of European international relations prior to the
Peace of Westphalia, gave way to the doctrine of the balance of power. The term gained significance after the Treaty of Utrechtin 1713, where it was specifically mentioned.
It was not until the beginning of the 17th century, when the science of international law assumed the
disciplineof structure, in the hands of Grotius and his successors, that the theoryof the balance of power was formulated as a fundamental principle of diplomacy. In accordance with this new discipline, the European states formed a sort of federal community, the fundamental condition of which was the preservation of a 'balance of power, i.e. such a disposition of things that no one state, or potentate, should be able absolutely to predominate and prescribe laws to the rest. And, since all were equally interested in this settlement, it was held to be the interest, the right, and the dutyof every power to interfere, even by force of arms, when any of the conditions of this settlement were infringed upon, or assailed by, any other member of the community.
This 'balance of power' principle, once formulated, became an
axiomof political science. Fénelon, in his "Instructions", impressed the axiom upon the young Louis, duc de Bourgogne. Frederick the Great, in his "Anti-Machiavel", proclaimed the 'balance of power' principle to the world. In 1806, Friedrich von Gentzre-stated it with admirable clarity, in "Fragments on the Balance of Power". The principle formed the basis of the coalitions against Louis XIV and Napoleon, and the occasion, or the excuse, for most of the wars which Europe experienced between the Peace of Westphalia(1648) and the Congress of Vienna(1814), especially from the British vantage point (including, in part, World War I).
During the greater part of the 19th century, the series of national upheavals which remodelled the map of Europe obscured the balance of power. Yet, it underlay all the efforts of
diplomacyto stay, or to direct, the elemental forces let loose by the French Revolution. In the revolution's aftermath, with the restoration of comparative calm, the principle once more emerged as the operative motive for the various political alliances, of which the ostensible object was the preservation of peace.
It has been argued by historians that in the sixteenth century England came to pursue a foreign policy which would preserve the equilibrium between Spain and France, which evolved into a balance-of-power policy:
The continental policy of England [after 1525] was fixed. It was to be pacific, mediating, favourable to a balance which should prevent any power from having a hegemony on the continent or controlling the Channel coasts. The naval security of England and the balance of power in Europe were the two great political principles which appeared in the reign of Henry VIII and which, pursued unwaveringly, were to create the greatness of England. [J. Pirenne, "The Tides of History: From the Expansion of Islam to the Treaties of Westphalia: Volume II" (London: 1963), p. 429.]
In 1579 the first English translation of Guicciardini's "
Storia d'Italia" or "History of Italy" popularised Italian balance of power theory in England. This translation was dedicated to Elizabeth I of Englandand claimed that "God has put into your hand the balance of power and justice, to poise and counterpoise at your will the actions and counsels of all the Christian kings of your time". [Michael Sheehan, "The Balance of Power: History & Theory" (Routledge, 2000), p. 35.]
Sir Esme Howard wrote that England adopted the balance of power as "a corner-stone of English policy, unconsciously during the sixteenth, subconsciously during the seventeenth, and consciously during the eighteenth, nineteenth and twentieth centuries, because for England it represented the only plan of preserving her own independence, political and economic". [Sir Esme Howard, 'British Policy and the Balance of Power', "The American Political Science Review", Vol. 19, No. 2. (May, 1925), p. 261.]

*Waltz, K. N. (1979). Theory of International Politics. New York: Random House. Waltz described IR in a systemic way, consisting of an anarchic structure and interacting units. His BOP-theory says that (smaller, weaker) states will balance the power or preponderance of more powerful ones to ensure that the latter do not become too powerful and dominate all other. For Waltz, a bipolar structure, as given in the Cold War, seems to be the best, i.e. the most peaceful one. Most relevant for his theory are chapters 1, 4-6.
*Walt, S. (1987). The Origins of Alliances. Walt puts the BOP-theory on a new basis and calls it balance-of-threat (BOT) theory, since some states do not balance each other, because they do not perceive one another as threats (e.g. the West in the Cold War, worked together against the Warsaw Pact, but didn't balance each other).
*Mearsheimer, J. J. (2001). The Tragedy of Great Power Politics. New York: W. W. Norton. Mearsheimer tries to mend BOP theory after it was unable to predict or explain the end of the Cold War. He describes himself as an "offensive realist" and believes that states do not simply balance, but because they want to survive in an anarchical system they get frequently aggressive. This is in contrast to Waltz, whom he describes as "defensive realist", who says that states primarily seek survival through balancing. Mearsheimer is an ardent critic of other IR theories (such as
neoliberalism, constructivism etc.) and warns heavily of the Chinese rise in their relative power position.
