Lord Acton and "the Insanity of Nationality"

Abstract

The sixty-year period that culminated in the First World War witnessed a momentous transformation in the European state system. Italian and German unification, the expulsion of the Ottomans from southeastern Europe, the destruction of the three remaining empires—the Austrian, German, and Russian—as casualties of the war, their replacement by a band of successor states stretching from the Baltic to the Balkans: these developments completely altered the face of Europe, as dynastic states gave way to nation-states. Looking back on this transformation once the war was over, many Europeans believed the decision to rebuild their continent on the basis of nation-states made perfect sense. To establish the principles of self-determination and democracy would contribute to peace and prosperity by solving the nationalities problem that had caused such mischief in the past. But in the 1860s, as this transformation was just beginning, the question looked very different, especially to the young John Dalberg Acton—the future Lord Acton, famous for the Cambridge Modern History—as he contemplated without benefit of hindsight the rise of the modern nation-state. 1 [End Page 129]
