In 1776, the Landgraviate of Hesse-Cassel was a financially robust but monetarily complex state within the Holy Roman Empire. Its ruler, Landgrave Frederick II, had amassed great wealth, largely through a notorious system of leasing Hessian soldiers as mercenaries to foreign powers, most notably to Great Britain for service in the American Revolutionary War. This substantial income, however, existed alongside a convoluted currency system typical of the German territories of the time. The official unit of account was the
Reichsthaler, but in practice, a multitude of physical coins—both domestic and foreign—circulated, including
Taler,
Gulden,
Kreuzer, and
Albuses, all with fluctuating exchange rates.
The monetary landscape was defined by the
Konventionsmünzfuß of 1753, a regional treaty that attempted to standardize coinage among several German states, including Hesse-Cassel. This system established a fixed silver content for the
Konventionsthaler. However, the landgravate also issued its own lower-quality
Landmünze (local coinage) for everyday domestic trade, creating a persistent duality between "good" convention money and "inferior" local money. Furthermore, a significant portion of the mercenary subsidy payments from Britain was received in high-quality British specie, which further complicated the circulating mix of silver.
Consequently, merchants and citizens in Hesse-Cassel in 1776 navigated a challenging environment of constant calculation and exchange risk. While the state treasury was famously full, the actual currency in daily use was a heterogeneous and often unstable blend. This situation required frequent official ordinances to adjust exchange rates and combat the outflow of good silver, making the monetary system a source of administrative headache even as the landgrave's foreign policy filled the coffers.
