International Relations and the Study of History
International relations and history are inextricably linked, and with good reason. This link is centuries old: Thucydides’ History of the Peloponnesian War, one of the very earliest and one of the very greatest historical works of all time, is widely regarded as the founding textbook of international relations. Still, those two disciplines are legitimately separate. A somewhat clear boundary between them can probably be drawn around three lines of demarcation: (1) past versus present, (2) idiographic versus nomothetic, and (3) description versus analysis. The utility of history for the analysis of international affairs has been taken for granted since time immemorial. History is said to offer three things to international relations scholars: (1) a ready source of examples, (2) an opportunity to sharpen their theoretical insights, and (3) historical consciousness, that is, an understanding of the historical context of human existence and a corresponding ability to form intelligent judgment about human affairs. This tradition continued well after international relations firmly established itself as a recognized separate discipline some time after World War II, and would remain virtually unchallenged until the 1960s. Since the 1960s, attitudes toward history have diverged within the international relations community. Some approaches, most notably the English school and the world system analysis, have almost by definition thriven on history. History plays a fundamental role in the critical-constructivist approach, while realist scholars continue to draw regularly on history. History is far less popular, though not absent from works belonging to the liberal-idealist approach. Postmodernism is the one approach that is almost completely antithetical to the analytical use of history. Postmodernists have characterized history as merely another form of fiction and question the existence of objective truth and transhistorical knowledge. One cannot exclude the possibility that postmodernism is correct in this respect; however, it is highly unlikely that uncountable generations of people have been victims of mass deception or mass psychosis regarding the utility of history, not least in the analysis of international relations.
