The eras of the French Revolution and Napoleon brought a series of major changes to France which the Bourbon Restoration did not reverse. First, France was now highly centralized, with all important decisions made in Paris. The political geography was completely reorganized and made uniform, dividing the nation into more than 80 "départements" which have endured into the 21st century. Each department had an identical administrative structure, and was tightly controlled by a prefect appointed by Paris. The thicket of overlapping legal jurisdictions of the old regime had all been abolished, and there was now one standardized legal code, administered by judges appointed by Paris, and supported by police under national control.
