Napoleon's conquests had a profound impact on Europe, reshaping its political landscape through the spread of revolutionary ideals and the establishment of new governance structures. As he expanded the French Empire, Napoleon implemented legal reforms, such as the Napoleonic Code, which promoted concepts like equality before the law and secular governance. These changes influenced many European nations, fostering nationalism and reform movements. However, his aggressive expansion also led to widespread resistance and conflict, culminating in the eventual formation of coalitions against France. Ultimately, his downfall and the Congress of Vienna in 1815 sought to restore order and balance, but the seeds of nationalism remained deeply rooted.
