One major consequence of the Napoleonic Wars (1803-1815) was the significant redrawing of the map of Europe. The wars initiated by Napoleon led to the rise of nationalism and the emergence of modern nation-states. The Congress of Vienna in 1815 aimed to restore stability by balancing power among European nations and suppressing revolutionary movements. Additionally, the wars weakened traditional monarchies and fueled political change, paving the way for future revolutions and shaping European politics throughout the 19th century.
