Campagna e Marittima Province
The Campagne and Maritime Province (Latin Campaniæ Maritimæque Provincia, Italian Provincia di Campagna e Marittima) was one of the seven provinces of the Papal States from the 12th century to the end of the 18th.
The province was established by Pope Innocent III in the year 1198, with Frosinone as its capital. Innocent's aim was to counter a tendency towards self-government in some of the towns in the south of his domains, such as Alatri, Ferentino, Velletri and Terracina, by installing a garrison at Ferentino. Even before that the 'Roman Campagne and the Maritime Province' was part of the Patrimony of St Peter.
In 1357, the establishment of the province was confirmed by the Constitutiones Sanctæ Matris Ecclesiæ.
The province was administered by a class of feudal 'Roman barons'.
Marittima e Campagna
Marittima e Campagna was a papal legation (IV Legation) from 1850 until 1860, when it was annexed by the Kingdom of Sardinia as part of the reunification of Italy. It covered a slightly larger area than the old Campagna and Maritime province.
