In 1030, the first Norman foothold in the Mezzogiorno was created when Sergius IV of Naples gave the town and vicinity of Aversa as a county to Ranulf Drengot. The following are the counts of Aversa:

• Rainulf I Drengot 1020-1045

• Asclettin 1045 (nephew)

• Rainulf II Trincanocte 1045-1048 (cousin)

• Herman 1048-1049 (son)

• Richard I 1049-1078 (cousin)

In 1058, Richard conquered the Principality of Capua and thereafter the counts of Aversa were, more importantly, princes of Capua.
