In the summer of 1914 it had been more than forty years since the last major European war. That period had witnessed unprecedented economic growth and the flourishing of culture. Lasting peace was conducive to prosperity, technological progress, and social change. Between the Franco-Prussian war of 1871 and the outbreak of the Great War in 1914 trams appeared on the streets of European cities, and the bigger capitals – London, Paris, Berlin, Budapest – acquired underground metro lines. New factories were built and the urban proletariat grew so rapidly that politicians began to vie for its support. Although the European powers pursued overseas campaigns, the latter’s impact on the daily life of Europeans was limited to articles in the morning press. Nor were peace and development the sole preserve of the West. In Central and Eastern Europe, too, war was not within living memory for the vast majority of citizens.
