Even in 1799 the revolution seemed to have failed, by 1815 it seemed canceled and had widespread results. The feudalism that had been part of Europe since the 9th century was abolished and the Napoleonic Code established social order and contractual relations. The French Revolution unified France and, through nationalism, strengthened the power of the national state. The revolution as well as the Napoleonic Wars also destroyed the old structure of Europe and spread nationalism throughout Europe. The widespread anomaly of nationalism led to the unification of Germany and Italy. The French Revolution is undeniably one of the most monumental events in history and its impact had an irrevocable effect on the 19th century.
