The Treaty of Vienna of 1815 was the formal agreement of the allied powers – Austria, Great Britain, Prussia and Russia to draw up a settlement for Europe.
The main goal of this treaty was to undo all the changes that were brought about in Europe during the reign of Napoleon wars.
The Bourbon dynasty, which had been deposed during the French Revolution, was restored to power, and France lost the territories it had annexed under Napoleon.
A series of states were set up on the boundaries of France to prevent French expansion in future.
Thus the kingdom of the Netherlands, which included Belgium, was set up in the north and Genoa was added to Piedmont in the south.
Prussia was given important new territories on its western frontiers, while Austria was given control of northern Italy.
But the German confederation of 39 states that had been set up by Napoleon was left untouched.
In the east, Russia was given part of Poland while Prussia was given a portion of Saxony.
The main intention was to restore the monarchies that had been overthrown by Napoleon, and create a new conservative order in Europe.
