Mein Kampf is a book by Nazi leader Adolf Hitler. It combines elements of autobiography with an exposition of Hitler's political ideology. Hitler began the dictation of the book while imprisoned for what he considered to be "political crimes" after his failed Putsch in Munich in November 1923. Though Hitler received many visitors earlier on, he soon devoted himself entirely to the book. As he continued, Hitler realized that it would have to be a two-volume work, with the first volume scheduled for release in early 1925. The prison governor of Landsberg noted at the time that "he [Hitler] hopes the book will run into many editions, thus enabling him to fulfil his financial obligations and to defray the expenses incurred at the time of his trial."
