1/2 Kreuzer - William II and Frederick William

Hesse-Kassel's coinage of the 1830s was issued under the joint reign convention recognizing both the sitting Elector and his heir — an arrangement that reflected dynastic anxiety more than administrative necessity. William II was by then effectively sidelined by mental incapacity, with actual governance increasingly handled by Frederick William, who would formally succeed as Frederick William I in 1847.

KM#593 is a minor copper piece from a small electorate that would cease to exist entirely in 1866, when Prussia annexed Hesse-Kassel following its support for Austria in the Austro-Prussian War.
