Explanation:
Congress of Vienna
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
Conservative Order
The Conservative Order is a term applied to European political history after the defeat of Napoleon in 1815. From 1815 to 1830 a conscious program by conservative statesmen, including Metternich and Castlereagh, was put in place to contain revolution and revolutionary forces by restoring old orders, particularly previous ruling aristocracies.
Britain, Prussia, Russia, and Austria renewed their commitment to prevent any restoration of Bonapartist power and agreed to meet regularly in conferences to discuss their common interests. This period contains the time of the Holy Alliance, a military agreement. The Concert of Europe was the political framework that grew out of the Quadruple Alliance in November 1815.
Diplomatic Consequences of the Congress of Vienna
Despite the efforts of the Great Powers of Europe to prevent conflict and war with the Congress of Vienna, in many ways the Congress system failed by 1823. The rest of the 19th century was marked by more revolutionary fervor, more war, and the rise of nationalism.
The battle of Antietam led to the Emancipation proclamation.
