But the patrimonies in the vicinity of Rome (the successors to the classical latifundia in the Ager Romanus), which had begun to form in the 7th century, were the most numerous. Most of the remote patrimonies were lost in the eighth century, so the patrimonia around Rome began to be managed with especial care, headed up by deacons directly subordinate to the pope. Other Italian patrimonies included the Neapolitan with the Island of Capri, that of Gaeta, the Tuscan, the Patrimonium Tiburtinum in the vicinity of Tivoli, estates about Otranto, Osimo, Ancona, Umana, estates near Ravenna and Genoa and lastly properties in Istria, Sardinia and Corsica.
