Answer:
1 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.
2 . Great Britain, Russia, Prussia, and Austria (the Quadruple Alliance) made most of the decisions at this conference known as the Congress of Vienna.
3 . The Congress of Vienna was dominated by the allied Great Powers that defeated Napoleon -- Austria, Prussia, Great Britain, and Russia.
4 Austria was given control of northern Italy. The German confederation of 39 states set up by Napoleon was left untouched. Russia was given part of Poland and Prussia was given part of Saxony. Monarchy was restored and a new conservative order was created in Europe.
