How did the representatives at the Congress of Vienna try to create balance of power in Europe after the defeat of Napoleon?

Explanation:

As the four major European powers (Britain, Prussia, Russia, and Austria) opposing the French Empire in the Napoleonic Wars saw Napoleon’s power collapsing in 1814, they started planning for the postwar world. The Treaty of Chaumont of March 1814 reaffirmed decisions that would be ratified by the more important Congress of Vienna of 1814–15. The Congress of Vienna was the first of a series of international meetings that came to be known as the Concert of Europe, an attempt to forge a peaceful balance of power in Europe. It served as a model for later organizations such as the League of Nations in 1919 and the United Nations in 1945. They included the establishment of a confederated Germany, the division of French protectorates and annexations into independent states, the restoration of the Bourbon kings of Spain, the enlargement of the Netherlands to include what in 1830 became modern Belgium, and the continuation of British subsidies to its allies. The Treaty of Chaumont united the powers to defeat Napoleon and became the cornerstone of the Concert of Europe, which formed the balance of power for the next two decades. The basic tenet of the European balance of power is that no single European power should be allowed to achieve hegemony over a substantial part of the continent and that this is best curtailed by having a small number of ever-changing alliances contend for power.

The Congress of Vienna dissolved the Napoleonic world and attempted to restore the monarchies Napoleon had overthrown, ushering in an era of reaction. Under the leadership of Metternich, the prime minister of Austria (1809–48), and Lord Castlereagh, the foreign minister of Great Britain (1812–22), the Congress set up a system to preserve the peace. Under the Concert of Europe, the major European powers—Britain, Russia, Prussia, Austria, and (after 1818) France—pledged to meet regularly to resolve differences. The goal was not simply to restore old boundaries but to resize the main powers so they could balance each other and remain at peace. The leaders were conservatives with little use for republicanism or revolution, both of which threatened to upset the status quo in Europe. This plan was the first of its kind in European history and seemed to promise a way to collectively manage European affairs and promote peace.
