The MGH section Diplomata working at the Austrian Institut für Mittelalterforschung at the Österreichische Akademie der Wissenschaften, Abteilung Editionsunternehmen und Quellenforschung has now completed the edition of the charters of Emperor Otto IV (1198-1218) to be published in volume 13 of the Diplomata series "Die Urkunden der deutschen Könige und Kaiser". The edition comprises all 339 known charters and deperdita issued during the rule of Otto IV as Roman-German King resp. Emperor.
To shorten the wait for the final printed publication, since 2019 the MGH make digital pre-print versions of the completed charter editions available online; the pre-print edition is updated on a yearly basis.
Last year, we were able to complete the remaining 42 documents, amounting to a sum total of 339 royal and imperial charters of Otto IV that are now available in our digital pre-print edition.
