The nineteenth century system: balance of power or political equilibrium?

Abstract

Students of international politics do not need to be told of the unsatisfactory state of balance of power theory. The problems are well known: the ambiguous nature of the concept and the numerous ways it has been defined, the various distinct and partly contradictory meanings given to it in practice and the divergent purposes it serves (description, analysis, prescription, and propaganda); and the apparent failure of attempts clearly to define balance of power as a system and specify its operating rules. Not surprisingly, some scholars have become sceptical about the balance of power ‘system’ and a few have even denied that balance of power politics prevailed in the nineteenth century. None of the methods generally used seems to promise much help. These have included studying the views and theories of balance of power held by individual publicists, theorists, and statesmen, making case studies of the balance of power in certain limited periods, analysing events and policies within an assumed balance of power framework, or constructing theoretical analyses comparing the supposed system of balance of power to other systems. Undoubtedly a method for operationalizing the study of the balance of power would be very valuable, and efforts to do this have yielded useful information. But the obstacles to establishing reliable indices of power and status and the problems of quantifying alignments and co-operation-conflict ratios in international affairs are formidable indeed.
