After this little is known from historical records about the abbey and the city until the 19th century. In 1798-1799 and 1810-1814 French troops under Napoleon entered the city, plundering the monasteries and the churches. In 1849 and 1867 Giuseppe Garibaldi conquered the city as part of his campaign to end the temporal rule of the Pope and unify Italy: in 1870 the city became definitively part of the Regno d'Italia.
