Great Britain's economic blockade of Germany in World War I was one of the key elements to the victory of the Entente. Though Britain had been the leading exponent of blockades for two centuries, the World War I blockade was not effective at the outbreak of hostilities.

In his study of the Allied blockade of 1915-1919, Vincent examines the rationale and impact of this first large-scale use of food as a weapon in the twentieth century. Vincent demonstrates that the collapse of the German war effort was induced as much by prolonged hunger as by military reversal. Under blockade since 1915, the starving Germans were, by 1918, in a state of growing anarchy. Remarkably, however, the armistice ending hostilities specifically required the continuation of the blockade until such time as German signatures had been affixed to a peace treaty.
