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.

Napoleon was responsible for spreading the values of the French Revolution to other countries, especially in legal reform and the abolition of serfdom.[269]

After the fall of Napoleon, not only was Napoleonic Code retained by conquered countries including the Netherlands, Belgium, parts of Italy and Germany, but has been used as the basis of certain parts of law outside Europe including the Dominican Republic, the US state of Louisiana and the Canadian province of Quebec.[270] The memory of Napoleon in Poland is favorable, for his support for independence and opposition to Russia, his legal code, the abolition of serfdom, and the introduction of modern middle class bureaucracies.[271]

Napoleon could be considered one of the founders of modern Germany. After dissolving the Holy Roman Empire, he reduced the number of German states from 300 to less than 50, paving the way to German Unification. A byproduct of the French occupation was a strong development in German nationalism. Napoleon also significantly aided the United States when he agreed to sell the territory of Louisiana for 15 million dollars during the presidency of Thomas Jefferson. That territory almost doubled the size of the United States, adding the equivalent of 13 states to the Union.[272]
