What measures were taken by the …

Napoleon set about introducing many of the reforms that he had already introduced in France. Through a return to monarchy Napoleon had, no doubt, destroyed democracy in France, but in the administrative field he had incorporated revolutionary principles in order to make the whole system more rational and efficient. Napoleon simplified administrative divisions, abolished the feudal system and freed peasants from serfdom and manorial dues. In the towns too, guild restrictions were removed. Transport and communication systems were improved. Peasants, artisans, workers and new businessmen and small-scale producers of goods, in particular, began to realize that uniform laws, standardized weights and measures, and a common national currency would facilitate the movement and exchange of goods and capital from one region to another.
The reactions of the local populations to French rule were mixed. Initially, in many places such as Holland and Switzerland, as well as in certain cities like Brussels, Mainz, Milan and Warsaw, the French armies were welcomed as harbingers of liberty. But the initial enthusiasm soon turned to hostility, as it became clear that the new administrative arrangements did not go hand in hand with political freedom. Increased taxation, censorship, forced conscription into the French armies required to conquer the rest of Europe.
