A revelatory new biography of Adolf Hitler from the acclaimed historian Brendan Simms. Adolf Hitler is one of the most studied men in history, and yet the most important things we think we know about him are wrong. As Brendan Simms's major new biography shows, Hitler's main preoccupation was not, as widely believed, the threat of Bolshevism, but that of international capitalism and Anglo-America. These two fears drove both his anti-semitism and his determination to secure the 'living space' necessary to survive in a world dominated by the British Empire and the United States. Brendan Simms's new book is the first to explain Hitler's beliefs fully, demonstrating how, as ever, it is ideas that are the ultimate source of the most murderous behaviour.
