Dirham - 'Abd Allah I

'Abd Allah I ruled the Aghlabid emirate for just five years before his death in 817, a reign short enough that his silver dirhams were never struck in quantity approaching those of his longer-lived successors. The Aghlabids operated as nominally Abbasid vassals, and their coinage maintained the Abbasid epigraphic formula as a deliberate signal of religious legitimacy — even as the dynasty exercised near-total political autonomy from Baghdad.
