Prince and History in the Mirror of the Chronicon Holtzatiae Auctore Presbytero Bremensi. This article deals with the issue of « regional » identity within the boundaries of a northern German principality in the late Middle Ages: the county of Holstein. The author, who draws upon his own MPhil dissertation, focuses himself on a quite ignored Latin chronicle from 1448, the so-called « Chronicon Holtzatiae » by an anonymous « Presbyter Bremensis ». He shows that first and foremost the chronicler, under the guise of history writing, buttresses the ambitions of the old and childless count of Holstein Adolf VIII of Schauenburg relating to the foreseeable « succession crisis » by excluding from the landscape of Holstein history throughout the centuries serious pretendants, i.e. the Schauenburg-Pinneberg. But, from a wider point of view, the « Presbyter Bremensis » also sketches a picture of « regional identity » which is typical of late medieval German dynastic historiography: the bond uniting the « terra » and the counts is depicted as a consubstantial one, constitutive of the very existence of the former, whereas other elements such as the regional law merely play a subordinate role.
