Restoration
Napoleon's defeaters met at the Congress of Vienna in 1815 to restore the absolute monarchy.
The great powers (Russia, UK, Prussia and Austria), reshaped the map of Europe, dividing the Napoleonic Empire.
They also created the Holy Alliance, a treaty of mutual assistance among European monarchs to any threat of liberal revolution that allowed military intervention. This would keep the absolutism in Europe.
However, the French Revolution had been too important and the new system as unable to prevent the growth of liberal and national sentiment.
