La geopolitica dell'antipapa Niccolò V attraverso il suo registro di cancelleria

A study of the chancery documents of the antipope Nicholas V, conveyed for the most part through the unpublished Reg. Vat. 118 if the Vatican Apostolic Archive, cannot forgo consideration of the nature and quantity of the surviving documents. That the extant licterae gratiae and executoriae - which date from May 18, 1328, to March 22, 1329 - were grouped according to diocese allows to make some initial considerations about the secular and religious support provided to the antipope and his local representatives. This paper examines the cases of Rome, Viterbo, Milan, Todi, and of the whole Ligurian region, taking into account the pecularities that characterize each of these areas.
