When Napoleon abdicated in 1814, Europe, and mostly France, was in great confusion. The Congress of Vienna met to draw the continent's political map again. A great number of European countries came to the congress. However, there were four most important powers that controlled the decision. These powers were the United Kingdom, Austria, Russia, and Prussia, represented by King Frederick William III. Another very important person at the Congress was Charles Maurice de Talleyrand. He was a French diplomat under Napoleon. France was considered an enemy state.
