Who desired the Great War? No nation benefitted from it. The war brought about the destruction of the Prussian Empire, stripped the British Empire of its ability to hold its colonies, slaughtered the French and starved Germany, inspired a revolution in Russia, and prepared the ground for a more terrible slaughter to come. The great powers didn’t want a war and they certainly didn’t need one. But their people wanted a war. To the surprise of the rulers across the Allies and the Central Powers, the idea of war was seized by the people of every nation.
