The vizier (Arabic: وزير, romanized: wazīr) was the senior minister of the Abbasid Caliphate, and set a model that was widely emulated in the Muslim world. Many viziers came to enjoy considerable power, even at times eclipsing the Abbasid caliphs and using them as puppets. The majority of the viziers were of non-Arab origin, and several were also notable patrons of poets and scholars, sponsoring the Translation Movement as well as religious works.
