This Nazi leader wrote the first part of his autobiography Mein Kampf while in Jail.

After an unsuccessful attempt to seize power in 1923, he was jailed for 9 months in Landsberg Fortress. While there he dictated the first part of his autobiography to his disciple Rudolf Hess.

Mein Kampf (My Struggle or My Battle) is a book which combines elements of Hitler’s autobiography and his political ideology. Volume 1 of Mein Kampf was published in 1925 and Volume 2 in 1926.

Hitler began the dictation of the book while imprisoned for what he considered to be “political crimes” 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.

Landsberg prison governor noted at the time that “He [Hitler] hopes the book will run into many editions, thus enabling him to fulfill his financial obligations and to defray the expenses incurred at the time of his trial.”
