Erich Friedrich Wilhelm Ludendorff (9 April 1865 – 20 December 1937) was a German general, the victor of the Battle of Liège and the Battle of Tannenberg.
From August 1916, his appointment as Quartermaster general (German: Erster Generalquartiermeister) made him the leader (along with Paul von Hindenburg) of the German war efforts during World War I.
His great strategic failure was that of Germany's great Spring Offensive in 1918 in its quest for total victory and he was forced out that October.After the war, Ludendorff became a prominent nationalist leader, and a promoter of the Stab-in-the-back myth, which posited that the German loss in World War I was caused by the betrayal of the German Army by Marxists, Bolsheviks, Freemasons and Jews who were furthermore responsible for the disadvantageous settlement negotiated for Germany in the Treaty of Versailles.
Consistently pursuing a purely military line of thought after the war, Ludendorff developed the theory of "Total War", which he published as Der totale Krieg (The Total War) in 1935.
In this work, he argued that the entire physical and moral forces of the nation should be mobilized, because peace was merely an interval between wars.
