Answer:
The main task of the congress was not only to restore the order violated by N. Bonaparte in Europe, the borders and status of the possessions seized by him, but also to develop such new international rules that would make attempts to upset the balance impossible. This balance, which arose from the chaos of interstate confrontations, rivalries, political unions and counter-unions, claims, threats, challenges and compromises, which made it a rather unstable system, should now rely not only on the absence of the “physical” ability of any state to violate it, but also on the development by all participants of such general agreements that would give a sense of justice to the new international order.
During the congress, for the first time, world powers sat down at the negotiating table to resolve disputed issues, which became the prerequisite for creating modern diplomacy.
The Congress of Vienna created on the borders of France a kind of stronghold from the Sardinian kingdom and Rhine Prussia. This cordon also included Switzerland, which was declared an eternally neutral state, and the new Kingdom of the Netherlands, formed from Holland and Belgium under the supreme authority of the Orange House, to which Luxembourg was also given in Germany.
The Congress of Vienna marked the end of the period of wars and started an era of lasting peace. With very few exceptions, the new map of Western Europe remained unchanged until 1859.
