This vol. provides a new analysis of the sources concerning the clash between Philip the Fair and Boniface VIII. Indeed, any attempt to study the constitutional and political position of the French clergy during the critical years at the turn of the 13th century must include an assessment of the ecclesiastical assemblies at which many clerical decisions were taken and through which the clerical voice was being heard. Although much progress has been made in the sorting and listing of materials relating to French diocesan synods, prior to this publication there had been no comparable sifting of the sources for the provincial councils.
