What has all this got to do with the Great War? In the study of history, as with so much else, context is everything. As Foch recognised, the First World War did not end on 11 November 1918, it shattered the old Europe, redrew its borders and created tensions and animosities which directly led to the Second. Any scholar of the war on Western Front will find this work an invaluable guide to what came next – and why. A thought-provoking dual biography of the two men whose political ideologies birthed the rise Nazi Germany’s Third Reich.
