A majority of the Saxons remained in continental Europe and long avoided becoming Christians and being incorporated into the orbit of the Frankish kingdom, but were decisively conquered by Charlemagne in a long series of annual campaigns. With defeat came the enforced baptism and conversion of the Saxon leaders and their people.
Under Carolingian rule, the Saxons were reduced to a tributary status. There is evidence that the Saxons, as well as Slavic tributaries like the Abodrites and the Wends, often provided troops to their Carolingian overlords.
