After the troubles of the French Revolution the Paris police force was reorganized by Napoléon I on February 17, 1800 as the Prefecture of Police, along with the reorganization of police forces in all French cities with more than 5,000 inhabitants. On March 12, 1829, a government decree created the first uniformed policemen in Paris and all French cities, known as "sergents de ville" ("city sergeants"), which the Paris Prefecture of Police's website claims were the first uniformed policemen in the world.
