Fazl Ibn Rabi

Abul Abbas Fazl Ibn Rabi’ (757-829), one of the viziers in Abbasid period. He was against Barmakids (Iranian family of secretaries and viziers of the early Abbasid caliphs), because in the reign of Abbasid caliph “Harun al-Rashid”; Barmakids appointed as the viziers. Eventually they were suppressed by Fazl Ibn Rabi’ and he himself became the vizier of Harun.After the death of Harun al-Rashid, Fazl remained the vizier of Amin (son of Harun). He had no relationship with Ma’mun ( the Abbasid caliph and brother of Amin), actually he was afraid of his caliphate and#### stimulated Amin to dethrone Ma’mun from the throne. Therefore Ma’mun sent his army to Baghdad, the commander of Amin was killed. As a result Amin’s rule became weakened and Ma’mun led a powerful government.
