At Quiercy on the Oise, the Frankish nobles finally gave their consent. Pepin promised in writing to give the Church certain territories, the first documentary record for the States of the Church. This document has not been preserved, but a number of citations during the decades immediately following indicate its contents, and it is likely that it was the source of the much interpolated "Fragmentum Fantuzzianum", which probably dates from 778 to 80. In the original document of Quiercy Pepin promised to restore to the pope the lands of central Italy conquered by Aistulf, especially in the exarchate and the Roman Duchy, and of a number of patrimonies in the Lombard Kingdom and the Duchies of Spoleto and Benevento. These lands had yet to be conquered by Pepin, so his promise was on condition that he did.
