Denier - Hartwig

Hartwig I served as Archbishop of Magdeburg during one of the most convulsive periods in medieval German history — the Investiture Controversy, which pitted Emperor Henry IV directly against the papacy over the right to appoint church officials. Magdeburg's archbishops held both ecclesiastical and secular authority over a strategically vital see on the eastern frontier, and their coinage functioned as a direct assertion of that dual power during a period when such claims were violently contested.

The Kluge Kar#431 attribution places this piece within a documented sequence of episcopal deniers from the region, though surviving examples are scarce enough that die linkage studies remain incomplete.
