In 1472, in the drastic redistribution of the Italian Provinces by the Vicar General, Christopher Martignoni, the houses in the Kingdom of Naples were separated from the Province of Rome. After 1598, the Neapolitan Province was also called the Province of Terra di Lavoro. Its houses were numerous, even after it gave rise to the Vicariate of Abruzzo (1573) and the Province of Calabria (1575) and contributed two houses to the reform of Santa Maria della Vita (1662). In 1725, the Province of Terra di Lavoro handed over five houses to a new Province of Naples formed from the ten granges of the Carmine Maggiore of Naples and the former convent of the Province of Monte Santo in the same city. This latter convent became the principal house of the Province. After all that, Terra di Lavoro still counted nineteen houses. A great deal of confusion arises due to the fact that the two names, Terra di Lavoro and Naples, are used indiscriminately in the records.
