Prehistory Archaeological sites excavated near Aversa have revealed human presence in the area since the
Neolithic period. Some say that the founding of the ancient city took place with the
Etruscans. One of the first bishops was the Norman
Guitmund (died c. 1090–95), a Benedictine monk, theologian, and opponent of
Berengar of Tours. The count of Aversa,
Richard I, was one of the chief leaders in the struggle against the Papal forces which culminated in the
Battle of Civitella del Fortore (1053) in
Beneventan territory; even
Pope Leo IX himself was captured at what turned into a rout in favour of the Normans. The astute Richard did not treat the pope as a prisoner, however, but escorted him back to Rome with full honours, a gesture that led to the conciliation of the Normans with the Church, the lifting of the ban of excommunication that had been laid upon Aversa.
Angevins After the Norman dynasty Aversa declined in importance: the Angevin kings of Naples came to Aversa mostly to hunt and hold court in the citadel, of which a few traces remain in via Roma in Aversa's historic centre. In particular
Queen Joanna I chose Aversa for her preferred seat. There a group of nobles threw her husband
Andrew from a window with a rope around his neck. His brother,
King Louis I of Hungary, head of the
Capetian House of Anjou, marched into Italy and at Aversa took his vengeance at a banquet of reconciliation, as Joanna escaped to Avignon. The presence of the court also benefitted Aversa by the institution of the Real Casa dell'Annunziata (about 1315) an orphanage and hospice that occupied a central place in Aversan public life.
Crown of Aragon When
Alfonso V of Aragon permanently enthroned the kingdom of Naples within the domains of the
Crown of Aragon, Aversa continued to maintain the privileges it had enjoyed. Soon the epidemics and subdivisions of land caused it to be relegated as a peripheral urban center of Naples. In fact, the palace of the Count of Almenara in Almenara (Castellón) is also known as the palace of the Count of Aversa. ==Demographics==
