Mein Kampf - "My Struggle") is an autobiography by the National Socialist leader Adolf Hitler, in which he outlines his political ideology and future plans for Germany. Volume 1 of Mein Kampf was published in 1925 and Volume 2 in 1926. The book was edited by Hitler's deputy Rudolf Hess.

Hitler began dictating the book to Hess while imprisoned for what he considered to be "political crimes" following his failed Putsch in Munich in November 1923. Although Hitler received many visitors initially, 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 governor of Landsberg 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." In 2016, following the expiry of the copyright held by the Bavarian state government, Mein Kampf was republished in Germany for the first time since 1945.
