WHI-Chap14-Abu al-Abbas
From SJS Wiki
Abu al-Abbas
Abu al-Abbas was an Abbasid caliph. Not only was he a caliph, but he was also the first (of the Abbasid Dynasty). He began " a campaign of extermination against the Umayyads, the Alids, other Abbāsid leaders who had become too popular, and all other claimants to power. He named himself as-Saffāḥ, “the blood-shedder,” because of his savage attacks. He established a firm legal and dynastic base for the ʿAbbāsids."[1]
This is not the Abbasid Caliphate at the time of Abu al-Abbas but at its greatest extent.
