The Alaholfings (occasionally Ahalolfings) were a noble family of Alemannia in the Early Middle Ages. They were related to the previous rulers of Alemannia, to the Bavarian Agilolfings and to the Geroldings. Their original power base was around the upper Neckar and Danube rivers. They came to possess lands in not only Alemannia, but also in Bavaria, Franconia and Italy.
The Ahalolfings are divided into two groups, the older and the younger. It is not certain how the two groups are related. The older group descends from a Berthold who was the joint founder, with Hnabi, of Reichenau Abbey in 724. His most famous descendant was Cadolah, Duke of Friuli, who defended the Pannonian plains into Italy from the Avars.
