⅙ Thaler - Ernest August

Ernest August, Duke of Cumberland, took the Hanoverian throne in 1837 only because Hanover operated under Salic Law — barring female succession — which severed its 123-year personal union with Britain the moment Victoria ascended to the Crown. His reign opened with immediate constitutional crisis: he unilaterally revoked the liberal constitution of 1833, triggering the famous protest of the Göttingen Seven, a group of professors that included the Brothers Grimm. The fractional thaler series issued under his name carries that political weight, struck for a kingdom whose king arrived under deeply contested circumstances.
