The book, dedicated to Thule Society member Dietrich Eckart, was an autobiography and exposition of his ideology. In "Mein Kampf", Hitler speaks at length about his youth, his early days in the Nazi Party and general ideas on politics, including the transformation of German society into one based on race, with some passages implying genocide. Published in two volumes in 1925 and 1926, it sold 228,000 copies between 1925 and 1932. In 1933, Hitler's first year in office, 1,000,000 copies were sold. The book acts as a reference, giving insight into the world view from which Hitler never wavered throughout his life.
