The treaty that finally brought an end to the Napoleonic Wars was the Treaty of Paris, signed in 1815. Following Napoleon Bonaparte's defeat at the Battle of Waterloo, the allies convened to restore stability to Europe. The treaty declared the end of hostilities and reaffirmed the territorial changes and political adjustments done in previous treaties. It established a new balance of power aimed at preventing future French expansion and maintained peace in Europe for a period through the Concert of Europe. The Treaty of Paris marked the end of an era and the restoration of monarchies across many parts of Europe.
