The Abbasid Caliphate crushed the Alid revolt when a rebel leader was mortally wounded in battle near Basra in present-day Iraq.

The Abbasid Caliphate or Abbasid Empire was the third caliphate to succeed the Islamic prophet Muhammad. It was founded by a dynasty descended from Muhammad's uncle, Abbas ibn Abd al-Muttalib, from whom the dynasty takes its name. After overthrowing the Umayyad Caliphate in the Abbasid Revolution of 750 CE (132 AH), they ruled as caliphs based in modern-day Iraq, with Baghdad being their capital for most of their history.

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 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.

Basra or Basrah is a port city in southern Iraq. It is the capital of the eponymous Basra Governorate, as well as the third largest city in Iraq overall, behind Baghdad and Mosul. Located near the Iran–Iraq border at the north-easternmost extent of the Arabian Peninsula, the city is situated along the banks of the Shatt al-Arab that empties into the Persian Gulf. It is consistently one of the hottest cities in Iraq, with summer temperatures regularly exceeding 50 °C (122 °F).
