The Congress of Vienna (1814-1815) aimed to restore stability and order in Europe following the upheaval of the Napoleonic Wars. Major outcomes included the redrawing of national boundaries to balance power, the restoration of monarchies, and the establishment of a framework for diplomacy among European powers. The congress introduced the principle of legitimacy, ensuring that rightful rulers were reinstated, and it promoted the concept of a balance of power to prevent any one state from becoming too dominant. The decisions made created a relatively stable political environment in Europe for decades, although they also sowed seeds for future conflicts.
