Light Denier - Henry X

Henry X ("the Black"), Duke of Bavaria from 1126, was among the most powerful Welf princes of his generation — powerful enough that Emperor Lothair III granted him Saxony as well in 1137, briefly uniting the two great duchies under a single hand. That political apex was short-lived; Henry died in 1139, the same year his rival Conrad III moved to strip the Welf family of both territories.

The light denier format reflects the broader debasement of south German silver coinage during the first half of the twelfth century, driven by fragmented minting authority across competing ecclesiastical and secular lords.
