In 626, the Basques rebelled against the Franks, with the bishop of Eauze being exiled on the accusation of supporting or sympathising with the Basque rebels, while in 635 a gigantic Frankish expedition led by the duke Arnebert and 9 more dukes launched an attack against the Basques, forcing them to retreat to the mountains, while Arnebert's column was defeated in Subola, maybe near Tardets. However, the Basques' relish was short-lived since they were brought to heel by Dagobert (Clichy, 636). By 626, it is certain that the duchy extended up to the Pyrenees and Vasconia had replaced Novempopulania as a preferred name for the geographical area between the Pyrenees and the Garonne. In 643, there was another rebellion to the north of the Pyrenees and in 642 and 654 they battled against the Visigoths to the south, in Saragossa. From 589 to 684, the Bishop of Pamplona was absent from the Visigothic Councils of Toledo, which is interpreted by some as the result of this city being under Basque or Frankish control.
