"The future belongs to peace," said the French economist Frédéric Passy.
Not everyone was so hopeful, "I shall not live to see the Great War," warned German Chancellor Otto von Bismarck, "but you will see it, and it will start in the east." It was Bismarck's prediction, rather than Passy's, that came true.
