Resumen de Un Comune e i suoi spazi normativi. Milano nel Thronstreit, l’autorialità del Liber consuetudinum Mediolani (1216) e il ruolo degli iudices tra diritto e politica

Alberto Spataro

• The essay considers the social and institutional events in Milan at the beginning of the 13th century. In particular, two key events are examined: the participation of some Milanese in Lateran Council IV (1215) and the promulgation of the Liber consuetudinum Mediolani (1216). In both contexts, the decisive role of the Milanese iudices is revealed. Moreover, the analysis of the miscellaneous manuscript suggests an active involvement of Passaguerra iudex in the preparation of Liber consuetudinum, a text aimed at giving normative homogeneity in the perspective of greater social compactness within the political space of the ambrosian civitas.
