On May 25 and 26, 2023, the Pontificia Università Gregoriana and the Archivum Historiae Pontificiae organised the conference I modi di governo del papa. Il tempo della sede vacante.
At this occasion, the Fraknói Research Group was again represented by its Vatican Archives Research Resident, Katalin Nagy.
The symposium was opened by Délio Mendonça SJ, Dean, François Jankowiak, Director of the Centre de recherches Droit et Sociétés Religieuses, and Roberto Regoli, Professor at Pontificia Universitá Gregoriana. The two-day series of conferences focused on the Sedes vacans periods in papal history when the papacy was vacant.
On the first day of the international conference, which brought together historians from all over Europe, Simone Raponi, Edouard Martin, François Jankowiak, Alessandra Rodolfo and others gave presentations.
The following day's presentations analysed the conclave from the perspective of the Church and the State, rather than from a symbolic, rhetorical approach. So did Massimo C. Giannini, Stefano Brancatelli, Roberto Regoli and Domenico Rocciolo. Finally, Maria Antonietta Visceglia, a renowned professor at La Sapienza Università di Roma, analysed the significance of the successive vacans of the See in the history of the papacy. The proceedings of the conference will be published in book form.
