Pope Gregory VI abdicated at Sutri on December 20, 1046, following the Synod of Sutri convened at the request of Emperor Henry III. In 1111 it was the seat of the treaty between Paschal II and Emperor Henry V; in 1146 and 1244 Eugene III and Innocent IV took refuge here, respectively. In 1244 it was conquered by Pietro di Vico, but was later taken by Pandolfo, count of Anguillara, who gave it back to the Papal States. The city witnessed the struggles between Guelphs and Ghibellines. In 1433 the condottiero Niccolò Fortebraccio set fire to Sutri, and from that point onward the city declined in favour of Ronciglione.
