Following Napoleon's defeats in 1814–1815, the Congress of Vienna returned France to its pre-war size and the number of departments was reduced to 86 (three of the original departments having been split).
Pärast Napoleoni kaotusi aastatel 1814–1815 andis Viini kongress Prantsusmaale tagasi tema sõjaeelse suuruse; departemangude arvu vähendati 86-ni, kui kolm algset departemangu jagati.
