With the granting of Roman citizenship, Abruzzo became an Augustan province, and took the name of Provincia Valeria, but it was greatly neglected in the imperial age, since it did not have great economic or strategic importance. After the fall of the Roman empire Abruzzo was the theater of the struggle between Byzantines and Ostrogoths and underwent heavy devastation. Later on, the Longobards divided it into two parts (afterwards the plural "Abruzzi" was used); the former annexed to the dukedom of Spoleto, the latter to that of Benevento. Between 1061 and 1150 the Normans defeated the Longobards and unified the region again, receiving it as a feud from Pope Hadrian IV; and ever since then Abruzzo was a part of the kingdom of the Two Sicilies.
In 1266 the Anjou proceeded to an administrative organization, then the domain of the Aragonese followed, then the Bourbons in the 17th century. All these rulers left the area in the utmost carelessness, turning it into one of the most desolate areas of Italy. In the Napoleonic period there were riots of farmers under Murat, then again under the Bourbons after the Restoration, and with the new Kingdom of Italy in 1860.
