What changes did Napoleon introduce to make the administrative system more efficient in the territories ruled by him?

Solution:

Napoleon introduced several changes to make the administrative system more efficient in the territories ruled by him. He formulated the Civil Code of 1804, also known as the Napoleonic Code. It did away with privileges based on birth. This law established equality before law, and also secured the right to property. Napoleon shortened administrative divisions, abolished the feudal system, and freed peasants from manorial dues and serfdom. Transport and communications were improved too.
