Henry IV's reign produced some of the most politically fractured coinage in the empire's history. The Investiture Controversy — his protracted war with Pope Gregory VII over the right to appoint bishops — destabilized ecclesiastical mints across Germany, and Speyer, as a cathedral city of particular imperial significance, sat at the center of that tension. Henry was buried there in 1106, in the Dom he had patronized heavily throughout his reign.
The fifty-year span of this attribution reflects genuine difficulty in assigning specific dies to narrower periods within his turbulent rule.
