The Goebbels Diaries are a collection of writings by Joseph Goebbels, a leading member of the German Nazi 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."
Goebbels began to keep a diary in October 1923, shortly before his 27th birthday, while unemployed and living in his parents' home at Rheydt in the Ruhr 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 but 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." From 1923 onwards he wrote 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. Diary entries of mid-December 1923 forward show Goebbels was moving towards the völkisch nationalist movement. Goebbels first took an interest in Adolf Hitler and Nazism in March 1924. 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). The trial garnered Hitler much press and gave him a platform for propaganda. 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.".
