The Goebbels Diaries are a collection of writings by Joseph Goebbels, a leading member of the National Socialist German Workers Party (NSDAP) and the Reich Minister of Public Enlightenment and Propaganda in Adolf Hitler's government from 1933 to 1945. The diaries, which have only recently been published in full in German and are available only in part in English, are a major source for the inner history of the Nazi Party and of its twelve years in power in Germany. The British historian Ian Kershaw wrote in the preface to his biography of Hitler: "For all the caution which must naturally be attached to Goebbels's regularly reported remarks by Hitler ... the immediacy as well as the frequency of the comments makes them a vitally important source of insight into Hitler's thinking and action."^[1]

Goebbels began to keep a diary in October 1923, shortly before his 26th birthday, while unemployed and living in his parents' home at Rheydt in the Lower Rhine region. He had been given a diary as a present by Else Janke, a young woman (of part-Jewish background) with whom he had a turbulent and eventually unsuccessful relationship, and most of his early entries were about her. His biographer Toby Thacker writes: "Writing a diary quickly became a kind of therapy for this troubled young man, and several historians have commented on how extraordinarily candid and revealing Goebbels was, particularly in his early years as a diarist."^[2] From 1923 onwards he wrote in his diary almost daily.

According to biographer Peter Longerich, Goebbels' diary entries from late 1923 to early 1924 reflected the writings of a man who was isolated, preoccupied by "religious-philosophical" issues, and lacked a sense of direction.^[3] Diary entries of mid-December 1923 forward show Goebbels was moving towards the völkisch nationalist movement.^[4] Goebbels first took an interest in Adolf Hitler and Nazism in March 1924.^[5] In February 1924, Hitler's trial for treason had begun in the wake of his failed attempt to seize power in Munich, Bavaria, during 8–9 November 1923 (this failed coup became known as the Beer Hall Putsch).^[6] The trial garnered Hitler much press and gave him a platform for propaganda.^[7] After Goebbels first met Hitler in July 1925, however, the Nazi leader increasingly became the central figure in the diary. By July 1926 Goebbels was so enraptured by Hitler speaking on "racial issues", that he wrote: "It is impossible to reproduce what [Hitler] said. It must be experienced. He is a genius. The natural, creative instrument of a fate determined by God. I am deeply moved."^[8]

Hitler became Chancellor in January 1933 and appointed Goebbels Propaganda Minister. Goebbels then published an edited version of his diaries for the period of Hitler's rise to power in book form, under the title Vom Kaiserhof zur Reichskanzlei: Eine historische Darstellung in Tagebuchblättern (From the Kaiserhof to the Reich Chancellery: a Historical Diary). The Kaiserhof was a Berlin hotel where Hitler stayed before he came to power. Goebbels's book was later published in English as My Part in Germany's Fight. Although this book was propagandist in intent, it provides insight into the mentality of the Nazi leadership at the time of their accession to power.

By July 1941 the diaries had grown to fill twenty thick volumes, and Goebbels realised that they were too valuable a resource to risk their destruction in an air raid. He therefore moved them from his study in his Berlin home to the underground vaults of the Reichsbank in central Berlin.^[9] From this time onwards, he no longer wrote the diaries by hand. Instead he dictated them to a stenographer, who later typed up corrected versions. He began each day's entry with a resume of the day's military and political news. Thacker notes: "Goebbels was already aware that his diary constituted a remarkable historical document, and entertained fond hopes of reworking it at some future stage for further publication, devoting hours to each day's entry."^[10] The involvement of a stenographer, however, meant that the diaries were no longer entirely secret, and they became less frank about personal matters.

By November 1944 it was evident to Goebbels that Germany was going to lose the war. He wrote in his diary: "How distant and alien indeed this beautiful world appears. Inwardly I have already taken leave of it." Realising that he was unlikely to survive the fall of the Third Reich, he gave orders that his diaries were to be copied for safekeeping, using the new technique of microfilm.^[11] A special darkroom was created in Goebbels's apartment in central Berlin, and Goebbels's stenographer, Richard Otte, supervised the work.^[12]

The last preserved entry dates to 10 April 1945 and contains only a report on the military situation, on which Goebbels did not comment.^[13] The boxes of glass plates containing the microfilmed diaries were sent in April 1945 to Potsdam just west of Berlin, where they were buried. The original handwritten and typed diaries were packed and stored in the Reich Chancellery.^[14] Some of these survived, and formed the basis for the publication of sections of the diaries (mainly from the war years) after the war. The boxes of glass plates at Potsdam were discovered by the Soviets and shipped to Moscow, where they sat unopened until they were discovered by Elke Fröhlich in March 1992. Only then did the publication of the full diaries become possible.^[15][16][17]
