Denier - Sico

Sico seized the principality of Benevento in 817 by imprisoning his predecessor Grimoald IV, ruling until his death in 832 as one of the more assertive Lombard princes of the south. Benevento had survived the Frankish destruction of the Lombard kingdom in 774 precisely because Charlemagne never fully subdued the south, and Sico exploited that autonomy aggressively — sacking Amalfi in 836 falls outside this issue's range, but his monetary output reflects a principality deliberately projecting independence from Carolingian authority.
