The Alid revolt of 762–763 or Revolt of Muhammad the Pure Soul was an uprising by the Hasanid branch of the Alids against the newly established Abbasid Caliphate. The Hasanids, led by the brothers Muhammad (called "the Pure Soul") and Ibrahim, rejected the legitimacy of the Abbasid family's claim to power. Reacting to mounting persecution by the Abbasid regime, in 762 they launched a rebellion, with Muhammad rising in revolt at Medina in September and Ibrahim following in Basra in November.
