Why was the Napoleonic rule over the region unpopular with some sections of people?
Napoleon rolled out a new Civil Code in 1804, known as the Napoleonic Code, which dismissed all the privileges ordained at birth and established equality before law and governance. This code was exported to all the regions that were brought under the rule of Napoleon in due course of time. This new code brought cheer to peasants, small businessmen. But nobility and landlords in France and feudal lords and manors in Italy and Switzerland did not receive this code well. Even in towns, guild restrictions were removed. So all the people who lost their privileges ordained due to birth or family status were unhappy with the new code. The initial enthusiasm of liberty that French occupation brought to Warsaw, Milan, Brussels and Mainz slowly waned and discontent grew among people of the newly occupied territories.
