Theudebert and Theuderic sent an army against the Wascones and with God's help defeated them, subjected them to their overlordship, and made them pay tribute. They appointed a duke named Genialis, who ruled them well.
Some scholars believe Genial was more of a tribal leader over whom the Frankish sovereigns exercised a vague suzerainty than a Frankish court official sent to the outskirts of the realm to lord it over a subject people. Sometime around 612, Sisebut, king of the Visigoths, reconquered the trans-Pyrenean portion of his realm, diminishing Frankish suzerainty in Vasconia. Genial was succeeded by Aeghyna.
