March of Zeitz
The March of Zeitz (German: Mark Zeitz) is a historiographical term, devised by early modern scholars, who assumed that a distinctive march (frontier province), encompassing the territory of the Bishopric of Zeitz and centered at the city of Zeitz (Upper Sorbian: Žič), was created in 968 by German king and emperor Otto I (936-973). Newer scholarly analyses have shown that primary sources do not mention a march under such name, also noting that some charters that contain data on those regions should be considered as later forgeries, thus leading modern researchers to question or reject traditional views regarding the effective existence of a distinctive march centered on Zeitz, as described in older historiography.
