Although in 1799 the revolution seemed to have failed, by 1815 it seemed quashed and had widespread results. Feudalism, which had been part of Europe since the 9th century, was abolished and the Napoleonic Code established the social order and contractual relations. The French Revolution unified France and increased the power of the nation state through nationalism. The revolution, along with the Napoleonic Wars, also destroyed the ancient 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 entire history of the 19th century.
