Dinar - Ziyadat Allah I

Ziyadat Allah I ruled Ifriqiya through one of its most turbulent stretches — his reign saw the catastrophic revolt of the Aghlabid army between 824 and 827, a mutiny so sustained and destructive that large parts of Tunisia were effectively ungovernable for years. Fiscal continuity was not guaranteed. That gold dinars continued to be struck to Abbasid weight standards throughout this period reflects the dynasty's structural dependence on maintaining caliphal legitimacy, even when military control of the province was tenuous at best.

The same reign also launched the conquest of Sicily in 827, a campaign that would outlast Ziyadat Allah himself by decades.
