to Christianity. It is recorded that at this time Old Saxony was divided into the ancient dioceses of Münster, Osnabrück, and Paderborn. However, by 695 the pagan Saxons had become extremely hostile to the Christian priests and missionaries in their midst and began to realize that their aim was to convert their overlord and destroy their temples and religion. Ewald the Fair was quickly murdered, but Ewald the Black they subjected to torture, and he was torn limb from limb. Afterwards the two bodies were cast into the Rhine. This is understood to have happened on 3 October 695 at a place called Aplerbeck, near Dortmund, where a chapel still stands. The two Ewalds are now celebrated in Westphalia as saints. Their reluctance to accept the new Christian religion and propensity to mount destructive raids on their neighbours would eventually bring them into direct conflict with Charlemagne, the powerful king of the Franks and later emperor. After a bloody and highly attritious thirty-year campaign between 772–804 the Old Saxons led by Widukind were eventually subdued by Charlemagne and ultimately forced to convert to Christianity. The bonds of kindred and clan were particularly strong among the Saxons, and in spite of many divisions the Saxons were an unusually homogeneous nation living as late as the 8th century as the early Germans described by Tacitus in Germania had lived. The long warfare with the Franks largely reduced but did not wholly obliterate their distinct cultural identity.

For more information on the later Duchy of Saxony that emerged after this campaign, see: Duchy of Saxony. Adam of Bremen, writing in the 11th century, compared the shape of Old Saxony to a triangle, and estimated from angle to angle the distance was eight days journey. In area Old Saxony was the greatest of the German tribal duchies. It included the entire territory between the lower Elbe and Saale rivers almost to the Rhine. Between the mouths of the Elbe and the Weser it bordered the North Sea. The only parts of the territory which lay across the Elbe were the counties of Holstein and Ditmarsch. The tribal lands were roughly divided into four kindred groups: the Angrians, along the right bank of the Weser; the Westphalians, along the Ems and the Lippe; the Eastphalians, on the left bank
