What happened at the congress of vienna in 1815

The Congress of Vienna in 1815 established national borders and policies for maintaining peace and a balance of power in Europe after Napoleon was defeated.

Explanation:

The Congress of Vienna was a gathering of leaders from the European nations that had defeated France and Napoleon - - and France was allowed representation also. (The French Minister of Foreign Affairs, Charles Maurice de Talleyrand-Périgord, had a role there.)

The delegates of the Congress of Vienna were interested in creating a balance of power in European politics. They did not want one nation to become too powerful again and press beyond its borders as France had done under Napoleon. The Congress of Vienna emphasized also the principal of "legitimacy" - - trying to put rulers in power that they thought to be the legitimate rulers of nations. (So, for instance, the Bourbon monarchy was restored in France.) They sought to prevent revolutions and unrest from breaking out again. (However, after a couple of decades, further revolutions did occur.)
