This book gives a definite contribution to a wide-ranging reflection on the medieval parish and the secular clergy, considered within a long-term chronological framework and a wide geographical scope that allows the analysis and confrontation of case studies from the Iberian kingdoms, Northern France, Italian Piedmont, Lombardy, Flanders, Transylvania, and North of the Holy Roman Empire. The chapters published in this book tells of dynamics of social, religious, and cultural exclusion and inclusion within lay communities, of the constitution of family elites and parish confraternities; it shows the composition and the recruitment rationales of the parish clergy and of some ecclesiastical chapters with a duty of Cura animarum; it examines the relations of the churches and parochial clergy with more prominent – secular and regular – ecclesiastical institutions in the context of the establishment and exercise of the right of patronage; finally, it explores the role of the secular clergy in the application of justice, based on the characterization of their cultural and juridical formation.
