The Zirids began as Fatimid vassals, governing Ifriqiya on behalf of Cairo after the Fatimid court relocated to Egypt in 973. Al-Mu'izz b. Badis broke that arrangement decisively in 1048, renouncing Ismaili Shia allegiance and declaring for the Sunni Abbasid caliphate in Baghdad — a political rupture that prompted the Fatimids to encourage the Banu Hilal and Banu Sulaym tribes to migrate westward into North Africa. The resulting invasions shattered Zirid power and depopulated large stretches of the Maghreb.
Dinars struck across this reign therefore fall into two sharply different political moments, before and after 1048. Those issued in the later years reflect a ruler whose territorial base was collapsing under nomadic pressure.
