Despite growing scepticism concerning the evidentiary value of normative legal sources, scholars continue to mine the legislative acts of ecclesiastical councils for insight into political, religious, and quotidian life in Frankish Gaul. Between the reigns of Clovis and Charlemagne (AD 511-768) at least eighty councils assembled, often on royal command, to discuss issues of concern to the episcopal and clerical attendees. Their published canons were intended to communicate ecclesiastical policy in the Frankish regnum. However, scholars have paid comparatively slight attention to the institution responsible for this body of legislation. This book remedies this lacuna by delineating the functions and modus operandi of the Frankish church council as an administrative body.
