Although the last Napoleonic fortress was surrender into Coalition hands by 5 December 1830, the Napoleonic Wars were not exactly over, but using that date to describe the end of the wars is misleading. In winter to spring 1831, insurgents across France and the Low Countries were posing a threat to the stability of the post war order and the threat of the Napoleonic veterans, officers and administration to the restored Bourbon rule in France under Charles X [who would be later replaced by Louis Philippe in 1832, after the final version of the Congress of Vienna was signed], who ruled from Versailles until Paris could be rebuilt, resulted in them being purged over the year. Also, rebellion in the urban areas was mainly contained with starvation, mobs and vigilante sponsored threats; which increased the unpopularity of the Bourbon king that he was replaced with Louis Philippe. The devastation inflicted on urban areas through poor supplies of food and medicine, along with damage inflicted by war, would lead to a heavy death toll during the cholera epidemic that entered France in 1831. The situation was even worse in the French countryside, but famine and cholera that decimated both the counter revolutionary French troops and the Seventh Coalition would halt the insurgencies by 1834 by also making life hard for the insurgents to live with, along with the disproportionate responses to the insurgencies.

Also, any newly independent or rebellious nations were split up [in the case of Italy and the states that composed the Confederation of the Rhine and a few Napoleonic created kingdoms], annexed [Belgium and Poland, the latter between the three partitioners of 1795 and with all of what was once the Grand Duchy of Warsaw under Russian rule, plus the former Balkan provinces of the Ottoman Empire to Ottoman rule] or reabsorbed by their previous rulers. Norway ended up being a part of Sweden. Saxony lost its northern portion to Prussia while all of Pomeriana and Lauenburg became a part of Prussia.

The case for France was more challenging. After such a disastrous and extremely long war, Prussia and Britain were receptive towards the dismemberment of France. However, the need to maintain a French national identity meant that in the end, the borders of 1790 were restored to France. In exchange, France would cede all her colonies [except from a few Caribbean islands] and ships of the line above 74 guns, plus any individual frigate with more than 40 guns or with heavier than 18 pounder guns itself [with both types of vessels restricted to 40 of each type at maximum allowed]. That said, there were very few [3] of the vessels to be ceded. Besides, France would have to stop colonization activities outside Europe [apart from demilitarized trade posts] for 10 years, reduce the cavalry force to 30,000 cavalry at most, renounce claims on Flanders and Belgium to Dutch control and surrender Italian territorial ambitions to the new kingdoms and Austria in present day Italy, Alsace Lorraine to the newly formed German Confederation, any territory south of the Pyrenees and Catalonia under French rule to Spain and acknowledged a Savoy that was enlarged westwards to Nice and with Lombardy incorporated into it. Although humiliating, the threat of dismemberment or harsher punishment, besides chaos nationwide, would lead to France accepting the terms on 28 November 1832 by signing the final versions of Treaty of Paris and the Congress of Vienna.

Other than mentioned above, the Congress of Vienna is similar to its actual, 1814-1815 version and territorial changes follow the actual congress unless mentioned or French applicable. Same applies to treaties not involving France.
