Denier - Frederick II Ulm

Frederick II issued this denier from Ulm during the period immediately following the Mainz Diet of 1235, where he promulgated the Landfrieden — the first imperial law written in German rather than Latin. The assembly effectively reasserted imperial authority over the German princes after years of Frederick's near-total preoccupation with Italian and Sicilian affairs. Ulm sat at a strategically critical point on the Danube trade routes, and the mint's activity during these years reflects the emperor's deliberate effort to project fiscal presence in Swabia.
