You are visiting the Franconian Circle, which was established in 1500 and is located in the centre of the Holy Roman Empire. Several of its territories now belong to the Bavarian region of Franconia. Historians Bernhard Ebneth and Rudolf Endres have written about the Franconian Circle in the 16th and 17th centuries and note that this circle developed a strong Eigendynamik (independent momentum). Franconia is a case in point to show that Reichskreise were more than executive organs. They often represented the very element that set new accents in the Empire (Ebneth & Endres, 1994, p. 42).

Franconia developed this special dynamic not only because of its infrastructurally prominent location but also because of its unique estate-based composition. The circle consisted of several prominent prince-bishoprics (Bamberg, Würzburg, Eichstätt) but also included influential secular princes. In addition, Franconia was rich in Grafen und Herren (counts and lords), meaning representatives of the lower nobility, and included imperial cities (Nuremberg, Rothenburg, Windsheim, Schweinfurt, Weißenburg), which could legally defend their interests directly.

After the Reformation, the Franconian Circle was also one of the confessionally most divided (or diverse) regions, which naturally led to conflict but also to cooperation, as the Franconian territories were economically interdependent.

As Bernhard Sicken has shown, this special structure of the Franconian Circle even led to its development towards a closer state-societal union in the 17th and 18th centuries. (Sicken, 1994, p. 62) In this period, the activities of the Franconian Circle continuously expanded and focused on police activities (in a broad sense). Meetings among the territories belonging to the circle happened more frequently and lasted longer, and they also introduced administrative innovations. Sicken has even raised the question of whether the Franconian Circle in the Enlightenment Age can thus be considered a confederation of states more than a mere province of the Empire.
