In 702, Arce was taken by the Lombard Gisulf I, thus becoming the possession of the Duchy of Benevento. In 846 and in 877 Arce was taken and plundered by the Saracens and again, in 937, by the Magyars. At the end of the 10th century Arce was donated by the Lombard prince of Capua to the monks of Montecassino, who held it until 1058, when the Norman Richard, Count of Aversa, took possession of it. In 1191 Arce was taken by Holy Roman Emperor Henry VI. In 1230, when he returned from the Holy Land, the latter's son Frederick II took over Arce again. In 1265 the town, defended in vain by the troops of Manfredi of Sicily, was taken by Charles I of Anjou. Under the Anjou, Arce was granted in fief first to the Cantelmo family, then to the Della Rovere family. The Della Rovere family held Arce as a fief until 1612, when it was bought by Giacomo Boncompagni (Duchy of Arce and Duchy of Sora). In 1796 the domination of the Boncompagni family ended and the town was aggregated to the Kingdom of Naples. The boundary with the Papal State was marked by 14 stones.
