Ever since the early 1930s, the history of Adolf Hitler's Mein Kampf in English has been complicated and has been the occasion for controversy. No fewer than four full translations were completed before 1945, as well as a number of extracts in newspapers, pamphlets, government documents and unpublished typescripts. Not all of these had official approval from his publishers, Eher Verlag. Since the war, the 1943 Ralph Manheim translation has been the most popular published translation, though other versions have continued to circulate.
