A powerful state apparatus. This included creating a police state with prefects overseeing administration in the provinces. Napoleon personally appointed competent prefects who reported directly to the Ministries of the Interior and Police. The prefects' duties included enforcing conscription, overseeing tax collection, monitoring food supplies and prices, maintaining local administration, gathering information on discontent, spying on politically dangerous individuals, spreading propaganda, and promoting commerce and trade. Napoleon also relied on the Minister of Police, Joseph Fouché, and the police to spy on rebellious individuals, search for deserters, supervise prisons, censor, and provide intelligence. Special courts were set up to deal with political crimes, and imprisonment without trial was reintroduced in 1810. Despite these measures, opposition was subdued, with only 2,500 people in prison for political offenses in 1814.
