Eberhard Jäckel (; 29 June 1929 – 15 August 2017) was a German historian. In the 1980s, he was a principal protagonist in the Historians' Dispute (Historikerstreit) over how to incorporate Nazi Germany and the Holocaust into German historiography and over Hitler's intentions. Career Born in Wesermünde, Hanover, Jäckel studied history at Göttingen, Tübingen, Freiburg, Gainesville, and Paris after World War II. After serving as an assistant and docent at Kiel until 1966, he taught from 1967 and followed Golo Mann as Professor for Modern History at the University of Stuttgart, a position that Jäckel retained until retirement in 1997. Jäckel's PhD dissertation was turned into his first book around 1966's Frankreich in Hitlers Europa ("France In Hitler's Europe"), a study of German policy towards France from 1933 to 1945. Jäckel first rose to fame through his 1969 book Hitlers Weltanschauung ("Hitler's Worldview"), which was an examination of Hitler's worldview and beliefs. Jäckel argued that far from being an opportunist with no beliefs, as had been argued by Alan Bullock, Hitler held to a rigid set of fixed beliefs and consistently acted from his "race and space" philosophy throughout his career. In Jäckel's opinion, the core of Hitler's worldview was his belief in what he saw as the merciless struggle for survival between the "Aryan race" and the "Jewish race" and in his belief that stronger "races" possessed large amounts of Lebensraum (living space). In Jäckel's view, everything that Hitler did throughout his life stemmed from the beliefs he had adopted in the 1920s. Jäckel has argued that Hitler felt there were three factors that determined a people's "racial value": its awareness of itself, the type of leadership that it had and its ability to make war. According to Jäckel, those for Germany meant ultranationalism, the Führerprinzip (Führer Principle) and militarism, and all three were the constants of Hitler's beliefs throughout his life. In Jäckel's opinion, Mein Kampf is a long rant against the three principles that Hitler saw as the antithesis of his three sacred principles: internationalism, democracy and pacifism. Jäckel asserts that for Hitler "the originators and bearers of all three counterpositions are the Jews". In Jäckel's view, Hitler in the Zweites Buch of 1928 established for the first time a logical link between his foreign policy conception and his antisemitism. They were synthesized in his view of history. With this, Hitler's Weltanschauung had finally achieved the kind
