Diplomatic history deals with the history of international relations between states. Diplomatic history can be different from international relations in that the former can concern itself with the foreign policy of one state while the latter deals with relations between two or more states. Diplomatic history tends to be more concerned with the history of diplomacy whereas international relations deals more with current events and creating a model intended to shed explanatory light on international politics.
The political history of the world is the history of the various political entities created by the Human race throughout their existence on Earth and the way these states define their borders. The history of political thinking goes back to antiquity. Political history, and thus the history of political thinking throughout human existence stretches though up to Medieval period and the Renaissance. In the Age of Enlightenment, political entities expanded from basic systems of self-governance and monarchy to the complex democratic and communist systems that exist of the Industrialized and the Modern Era, in parallel, political systems have expanded from vaguely defined frontier-type boundaries, to the definite boundaries existing today.
Although much of existing written history might be classified as diplomatic history—Thucydides, certainly, is among other things, highly concerned with the relations among states—the modern form of diplomatic history was codified in the 19th century by Leopold von Ranke, a the leading German historian of the 19th century. Ranke wrote largely on the history of Early Modern Europe, using the diplomatic archives of the European powers (particularly the Venetians) to construct a detailed understanding of the history of Europe wie es eigentlich gewesen ("as it actually happened."). Ranke saw diplomatic history as the most important kind of history to write because of his idea of the "Primacy of Foreign Affairs" (Primat der Aussenpolitik), arguing that the concerns of international relations drive the internal development of the state. Ranke's understanding of diplomatic history relied on the large number of official documents produced by modern western governments as sources, which he argued should be examined in an objective and neutral spirit.
In the 19th and early 20th centuries, work by prominent diplomatic historians such as Charles Webster, Harold Temperley, Alfred Pribram, R.H. Lord and B.E. Schmitt were mostly concerned with the events such as the Napoleonic Wars, the Congress of Vienna and the origins of the Franco-German War. A notable event in diplomatic history occurred in 1910 when the French government start to publish all of the archives relating to the war of 1870.
Ranke's understanding of the dominance of foreign policy, and hence an emphasis on diplomatic history, remained the dominant paradigm in historical writing through the first half of the twentieth century. This emphasis, combined with the effects of the War Guilt Clause in the Treaty of Versailles (1919) which ended the First World War, led to a huge amount of historical writing on the subject of the origins of the war in 1914, with the involved governments printing huge, carefully edited, collections of documents and numerous historians writing multi-volume histories of the origins of the war. In the interwar period, most diplomatic historians tended to blame of the all the Great Powers of 1914 for the First World War, arguing that the war was in effect everybody's responsibility. In general, the early works in this vein, including Fritz Fischer's controversial (at the time) 1961 thesis that German goals of "world power" were the principal cause of the war, fit fairly comfortably into Ranke's emphasis on Aussenpolitik.
For the first half of the 20th century, most diplomatic history working within the narrow confines of the Primat der Aussenpolitik approach was very narrowly concerned with foreign-policy making elites with little reference to broader historical forces. The most notable exceptions to this tendency were A. J. P. Taylor and William Medlicott in Britain, Pierre Renouvin in France, and William L. Langer in the United States. A sign of the future tendencies in diplomatic history occurred in 1939 with the publication of the British historian E. H. Carr's book The Twenty Years' Crisis which suggested that it was a flawed peace settlement in 1919 instead of the decisions of individual leaders that caused the problems of interwar Europe. Through The Twenty Years' Crisis was published just months before World War II began, the Japanese historian Saho Matusumoto wrote that in a sense, Carr's book began the debate on the origins of World War II.
By contrast, Sir Winston Churchill's 1948 book The Gathering Storm presented World War II as caused by the insane ambitions of Adolf Hitler who was unwillingly abetted by cowardly and weak-willed British and French leaders who chose appeasement over resistance. In the 1950s, almost all diplomatic history on the origins of World War II followed Churchill's lead in unsparingly condemning British and French leaders for appeasement in the 1930s. A group of French historians centered around Pierre Renouvin and his protégés Jean-Baptiste Duroselle and Maurice Baumont started a new type of international history in the 1950s that included taking into account what Renouvin called forces profondes (profound forces) such as the influence of domestic politics on French foreign policy. However, Renouvin and his followers still followed the concept of la décadence with Renouvin arguing that French society under the Third Republic was “sorely lacking in initiative and dynamism” and Baumont arguing that French politicians had allowed "personal interests" to override "any sense of the general interest". In 1979, Duroselle published a well-known book entitled La Décadence that offered a total condemnation of the entire Third Republic as weak, cowardly and degenerate.
The British historian A. J. P. Taylor's 1961 book The Origins of the Second World War claimed that Hitler had no master-plan for conquering the world and was instead an opportunistic leader seizing whatever chances he had for expansionism, and that the war that started over Poland in 1939 was due to diplomatic miscalculation on the part of the Germans, the British, the French and the Poles instead of being a case of German aggression. Taylor's book set off a huge storm in the 1960s that led to much reappraisal of the origins of World War II. British historians such as D.C. Watt, George Peden and David Dilks followed Taylor and argued that far being a case of a degenerate clique who had mysteriously seized control of British foreign policy in the 1930s, that appeasement was due to a number of structural economic and military factors that had limited British options. Reflecting the new interests, British historians such as Christopher Thorne and Harry Hinsley abandoned the previous focus on individual leaders to discuss the broader societal influences such as public opinion and narrower ones like intelligence on diplomatic relations.
At the same time, in 1961 when the German historian Fritz Fischer published Griff nach der Weltmacht, which established that Germany had caused the First World War led to the fierce "Fischer Controversy" that tore apart the West German historical profession. One result of Fischer's book was the rise in the Primat der Innenpolitik (Primacy of Domestic Politics) approach. As a result of the rise of the Primat der Innenpolitik school, diplomatic historians increasing started to play attention to domestic politics. In the 1970s, the conservative German historian Andreas Hillgruber, together with his close associate Klaus Hildebrand, was involved in a very acrimonious debate with the leftish German historian Hans-Ulrich Wehler over the merits of the Primat der Aussenpolitik ("primacy of foreign politics") and Primat der Innenpolitik ("primacy of domestic politics") schools. Hillgruber and Hildebrand made a case for the traditional Primat der Aussenpolitik approach to diplomatic history with the stress on examining the records of the relevant foreign ministry and studies of the foreign policy decision-making elite. Wehler, who favored the Primat der Innenpolitik approach, for his part contended that diplomatic history should be treated as a sub-branch of social history, calling for theoretically-based research, and argued that the real focus should be on the study of the society in question. Moreover, under the influence of the Primat der Innenpolitik approach, diplomatic historians in the 1960s, 70s and 80s start to borrow models from the social sciences.
A notable example of the Primat der Innenpolitik approach was the claim by the British Marxist historian Timothy Mason who claimed that the launch of World War II in 1939 was best understood as a “barbaric variant of social imperialism”. Mason argued that “Nazi Germany was always bent at some time upon a major war of expansion”. However, Mason argued that the timing of a such a war was determined by domestic political pressures, especially as relating to a failing economy, and had nothing to do with what Hitler wanted. In Mason's view in the period between 1936–41, it was the state of the German economy, and not Hitler's "will" or "intentions" that was the most important determinate on German decision-making on foreign policy. Mason argued that the Nazi leaders were deeply haunted by the November Revolution of 1918, and was most unwilling to see any fall in working class living standards out of the fear that it might provoke another November Revolution. According to Mason, by 1939, the “overheating” of the German economy caused by rearmament, the failure of various rearmament plans produced by the shortages of skilled workers, industrial unrest caused by the breakdown of German social policies, and the sharp drop in living standards for the German working class forced Hitler into going to war at a time and place not of his choosing. Mason contended that when faced with the deep socio-economic crisis the Nazi leadership had decided to embark upon a ruthless “smash and grab” foreign policy of seizing territory in Eastern Europe which could be pitilessly plundered to support living standards in Germany. Mason's theory of a "Flight into war" being imposed on Hitler generated much controversy, and in the 1980s he conducted a series of debates with economic historian Richard Overy over this matter. Overy maintained the decision to attack Poland was not caused by structural economic problems, but rather was the result of Hitler wanting a localized war at that particular time in history. For Overy, a major problem with the Mason thesis was that it rested on the assumption that in a way unrecorded by the records, that information was passed on to Hitler about the Reich's economic problems. Overy argued that there was a major difference between economic pressures inducted by the problems of the Four Year Plan, and economic motives to seize raw materials, industry and foreign reserve of neighboring states as a way of accelerating the Four Year Plan. Moreover, Overy asserted that the repressive capacity of the German state as a way of dealing with domestic unhappiness was somewhat downplayed by Mason.
In addition, because World War II was a global war, diplomatic historians start to focus on Japanese-American relations to understand why Japan had attacked the United States in 1941. This in turn led diplomatic historians to start to abandon the previous Euro-centric approach in favor of a more global approach. A sign of the changing times was the rise to prominence of such diplomatic historians such as the Japanese historian Chihiro Hosoya, the British historian Ian Nish, and the Japanese historian Akira Iriye, which was the first time that Asian specialists became noted diplomatic historians. The Cold War and decolonization greatly added the tendency to a more global diplomatic history. The Vietnam War led to the rise of a revisionist school in the United States, which led many American historians such as Gabriel Kolko and William Appleman Williams to reject traditional diplomatic history in favor of a Primat der Innenpolitik approach that saw a widespread examination of the influence of American domestic politics together with various social, economic and cultural forces on foreign-policy making. In general, the American Cold War revisionists tended to focus on American foreign policy decision-making with respect to the genesis of the Cold War in the 1940s and on how the United States became involved in Vietnam in the 1960s. Starting in the 1960s, a ferocious debate has taken place within Cold War histriography between the advocates of the “orthodox” school which saw the Cold War as a case of Soviet aggression such as Vojtech Mastny against the proponents of the “revisionist” school which saw the Cold War as a case of American aggression. Latterly, a third school known as "neo-orthodox" whose most prominent member is the American historian John Lewis Gaddis has emerged, which holds through the United States borne some responsibity for the Cold War, the lion's share of the responsibility goes to the Soviet Union.
In Europe, diplomatic history fell out of favor in the late Cold War era. Since the collapse of communism, there has been a renaissance, led especially by historians of the early modern era, in the history of diplomacy. The new approach differs from previous perspectives by the wholesale incorporation of perspectives from political science, sociology, the history of mentalities, and cultural history.
In the U.S. since 1980, the discipline of diplomatic history has become more relevant to and integrated with the mainstream of the historiographic profession, having been in the forefront of the internationalization of American historical studies. As a field that explores the meeting of domestic and international forces, the study of US foreign relations has become increasingly important for its examination of both the study of culture and identity and the exploration of political ideologies. Particularly shaped by the influence of studies of Orientalism and globalism, gender studies, race, and considerations of national identity, diplomatic history was often at the cutting edge of historical research. Despite such innovations, however, the core endeavor of diplomatic history remains the study of the state, which is also a key to its broadening appeal, since considerations of US state power are essential to understanding the world internationally.
