Rioni of Rome

According to tradition, Servius Tullius, sixth king of Rome, first divided the city into regiones, numbering four.

During administrative reorganization after the Roman Republic collapsed, the first emperor Augustus created the 14 regiones of Rome that were to remain in effect throughout the Imperial era, as attested by the 4th-century Cataloghi regionari, that name them and provide data for each.

In 1744 Pope Benedict XIV, because of frequent misunderstanding, decided to replan the administrative division of Rome, giving the responsibility of it to Count Bernardini.

After Napoleon lost his power there were no significant changes in the organization of the city until Rome became the capital of the newborn Italy.

The latest reform, which is still mostly valid, was made in 1972: Rome was divided in 20 circoscrizioni (later renamed municipi, one of which became later the independent municipality of Fiumicino) and 20 rioni (which together form the Centro Storico) constituted the first one, Municipio I.
