Following the fall of southern Ravenna in 902, the League of Napoli was recognized as a force to be reckoned with in Italy. Multiple battles with the Carolingians prevented them from gaining much territory following the fall of Ravenna, though it also prevented the Carolingians from taking territory from the League of Napoli. The Emirate of Sicily, at war with the Carolingians over Carolingian Sicily, offered an alliance to the League of Napoli. With Sicily on the League's side, the League was able to invade Spoleto.
