Reichskreis
In individual cases the membership of some areas is disputed. These include the Bavarian language area of Alt-Eichstätt and the Hessian-speaking region around Aschaffenburg, which was never part of the Franconian Imperial Circle. The affiliation of the city of Heilbronn, whose inhabitants do not call themselves Franks, is also controversial. Moreover, the sense of belonging to Franconia in the Frankish-speaking areas of Upper Palatinate, South Thuringia and Hesse is sometimes less marked.
