 The Imperial Knights with their tiny territories, of which there was a particularly large number in Franconia, were outside the Circle assembly and, until 1806, formed the Franconian Knights Circle ("Fränkischer Ritterkreis") consisting of six Knights' Cantons.Because the extent of Franconia, already referred to above, is disputed, there were many areas that might be counted as part of Franconia today, that lay outside the Franconian Circle.For example, the area of Aschaffenburg belonged to Electoral Mainz and was a part of the Electoral Rhenish Circle, the area of Coburg belonged to the Upper Saxon Circle and the Heilbronn area to the Swabian Circle.
