(, ) refers to the theory in German historiography that considers the German-speaking lands or the country of Germany itself to have followed a unique course from aristocracy to democracy unlike any other in Europe.

The modern school of thought by that name arose early during World War II as a consequence of the rise of Nazi Germany. In consequence of the scale of the devastation wrought on Europe by Nazism, the theory of German history has progressively gained a following inside and outside Germany, especially since the late 1960s. In particular, its proponents argue that the way Germany developed over the centuries virtually ensured the evolution of a social and political order along the lines of Nazi Germany. In their view, German mentalities, the structure of society, and institutional developments followed a different course in comparison with the other nations of the West.

19th century

The term was first used by German conservatives in the imperial period, starting in the late 19th century as a source of pride at the "Golden Mean" of governance that in their view had been attained by the German state, whose distinctiveness as an authoritarian state lay in taking the initiative in instituting social reforms and in imposing them without waiting to be pressured by demands "from below". That type of authoritarianism was seen to be avoiding both the autocracy of Imperial Russia and what they regarded as the weak, decadent and ineffective democratic governments of Britain and France. The idea of Germany as a great Central European power, neither of the West nor of the East, was to be a recurring feature of right-wing German thought right up to 1945.

The historian Hans-Ulrich Wehler of the Bielefeld School places the origins of Germany's path to disaster in the 1860s and the 1870s, when economic modernization took place, but political modernization did not happen, and the old Prussian rural elite remained in firm control of the army, diplomacy and the civil service. Traditional, aristocratic and premodern society battled an emerging capitalist, bourgeois and modernizing society. Recognizing the importance of modernizing forces in industry and the economy and in the cultural realm, Wehler argues that reactionary traditionalism dominated the political hierarchy of power in Germany, as well as social mentalities and in class relations ().Hans-Ulrich Wehler, (1995)

20th century During World War II Nazi Germany's occupation of Czechoslovakia in March 1939 and its invasion of Poland in September 1939 (the latter invasion immediately drawing France and Britain into World War II) provoked the drive to explain the phenomenon of Nazi Germany. In 1940, Sebastian Haffner, a German living in Britain, published Germany: Jekyll and Hyde, in which he argued it was Adolf Hitler alone, by the force of his peculiar personality, who had brought about Nazi Germany. In 1941, the British diplomat Robert Vansittart published The Black Record: Germans Past And Present, according to which Nazism was only the latest manifestation of what Vansittart argued were the exclusively German traits of aggressiveness and brutality. Other books with a thesis similar to Vansittart's were Rohan Butler's The Roots of National Socialism (1941) and William Montgomery McGovern's From Luther to Hitler: The History of Nazi-Fascist Philosophy (1946).

Early postwar period After Germany's defeat in World War II in 1945, the term lost its positive connotations from the 19th century and acquired its present negative meaning. There was much debate about the origins of this "German catastrophe" (as the German historian Meinecke titled his 1946 book) of Nazi Germany's rise and fall. Since then, scholars have examined developments in intellectual, political, social, economic and cultural history to investigate why German democracy failed during the Weimar Republic and which factors led to the rise of Nazism. In the 1960s, many historians concluded that the failure of Germany to develop firm democratic institutions in the 19th century had been decisive for the failure of the Weimar Republic in the 20th century.

Until the mid-1960s, the debate was polarized with most non-German participants at one pole and German participants at the other. Historians like Léon Poliakov, A. J. P. Taylor, and Lewis Bernstein Namier, echoed by journalists like the American William L. Shirer, portrayed Nazism as the inevitable result of German history, reflecting unique flaws in "German national character" that went back to the days of Martin Luther, if not before.

During the Raleigh Lecture on History in 1944, Namier stated that the German liberals in the Revolution of 1848 were "in reality forerunners of Hitler", whose views about the Poles and Czechs presaged the great international crises of 1938–39, and called the 1848 revolution "a touchstone of German mentality and a decisive element in East-European politics"Hamerow, Theodore "Guilt, Redemption and Writing German History" pages 53–72 from The American Historical Review, 1983. In his lecture, Namier described the 1848 revolution as "the early manifestations of aggressive nationalism, especially of German nationalism which derives from the much belauded Frankfurt Parliament rather than from Bismarck and "Prussianism". Namier concluded "had not Hitler and his associates blindly accepted the legend which latter-day liberals, German and foreign had spun around 1848, they might well have found a great deal to extol in the [] of the Frankfurt Assembly".

Taylor wrote in his 1945 book The Course of German History that the Nazi regime "represented the deepest wishes of the German people", and that it was the first and only German government created by the Germans as the Holy Roman Empire had been created by France and Austria, the German Confederation by Austria and Prussia and the Weimar Republic by the Allies. In contrast, Taylor argued, "but the Third Reich rested solely on German force and impulse; it owed nothing to alien forces. It was a tyranny imposed upon the German people by themselves". Taylor argued that Nazism was inevitable because the Germans wanted "to repudiate the equality with the peoples of eastern Europe which had then been forced upon them" after 1918. Taylor wrote that:

The American historian Peter Viereck wrote in his 1949 book Conservatism Revisited: The Revolt Against the Revolt 1815–1949:

Shirer in his 1960 book The Rise and Fall of the Third Reich argued for the view that German history proceeded logically from "Luther to Hitler" and saw Hitler's rise to power as an expression of German character, rather than of the international phenomenon of totalitarianism. Shirer encapsulated that by stating that "the course of German history... made blind obedience to temporal rulers the highest virtue of Germanic man and put a premium on servility."

The French historian Edmond Vermeil wrote in his 1952 book () that Nazi Germany was not "a purely adventitious episode appearing on the fringes of the German tradition". Instead, Vermeil contended that German nationalism had an especially aggressive character, which had been restrained only by Bismarck. After Bismarck's departure in 1890, Vermeil wrote, "It was after his fall, under William II, that this nationalism, breaking all barriers and escaping from the grip of a weak government, gave rise to a state of mind and a general situation that we have to analyze, for otherwise Nazism with its momentary triumphs and its terrible collapse will remain incomprehensible". Vermeil concluded that Germany will remain on a separate path, "always placing the spirit of its implacable technical discipline at the service of those visions of the future that its eternal romanticism begets".

Poliakov wrote that even if not all Germans supported the Holocaust, it was "tacitly accepted by the popular will".Marrus, Michael The Holocaust in History, Key Porter: Toronto 2000 page 86.

In contrast, German historians such as Friedrich Meinecke, Hans Rothfels, and Gerhard Ritter, joined by a few non-German historians such as Pieter Geyl, contended that the Nazi period had no relationship to earlier periods of German history and that German traditions were at sharp variance with the totalitarianism of the Nazi movement. Meinecke famously described Nazism in his 1946 book () as a particularly unfortunate () of history. Although opposed to what they regarded as Meinecke's excessively-defensive tone, Ritter and Rothfels have been joined by their intellectual heirs Klaus Hildebrand, Karl Dietrich Bracher and Henry Ashby Turner in contending that although the Nazi dictatorship was rooted in the German past, individual choices made during the later Weimar years led to the Nazi years. Though Bracher is opposed to the interpretation of German history, he does believe in a special German mentality (, ) that emerged in the late 18th century.Lukacs, John The Hitler of History, New York: Alfred A. Knopf, 1997 page 201. Bracher wrote that:

In response, Heinrich August Winkler argued that there was a before 1933 and that Germany was a country deeply influenced by the Enlightenment, which meant there was no point of comparison between Hitler on one hand and Pol Pot and Stalin on the other.
