Was there sympathy with the Saxons on the basis of ethnicity? Or sympathy with the Franks on the basis of religion (as the Anglo-Saxons and Franks were Christian while the German Saxons were pagan)? Or any political alliance with either side?
I've written about relations between the continental Saxons and their Anglo-Saxon cousins recently
