16th International Congress of Medieval Canon Law

Welcome to ICMCL XVI!

Dear colleagues,

We are pleased to be able to announce our new dates for the 16th International Congress of Medieval Canon Law. They are July 18-24, 2021. As announced previously, we intend to keep the program the same. We will re-invite those who had removed their name because of scheduling conflicts and/or lack of access to funding for July 2020. We will keep your name in the program unless you request that it be removed. In due time, we will release the updated program with the correct dates on each day.

We are grateful to the administration of Saint Louis University for supporting us and our scholarly community and for helping us secure these new dates.

We hope you all remain healthy and well, and it will surely be a great pleasure to see everyone when we gather, deo volente, in July 2021.

With all best wishes,

Atria Larson and Steve Schoenig, S.J.

The 16th International Congress of Medieval Canon Law, co-sponsored by ICMAC (Iuris Canonici Medii Aevi Consociatio/ International Society of Medieval Canon Law) and Saint Louis University, will take place on SLU’s campus in St. Louis, Missouri, USA, from Sunday, July 18, through Saturday, July 24, 2021.

These week-long, quadrennial Congresses, alternating sides of the Atlantic, constitute the premier academic conference in the field of medieval canon law. Traditionally they have drawn scholars from many countries, including not only medievalists and canonists, but also those who study related fields, such as Western jurisprudence and legal norms, Roman law, ecclesiastical and papal history, theology and biblical exegesis, manuscript studies, and the history of culture, society, and ideas.

Medieval canon law contributed to an international system of law for hundreds of years and had a significant impact on the development of Western legal norms, jurisprudence, and judicial procedure, as well as on the history of Christianity, especially the evolution of papal authority.
