Al-Muwaffaq, Abbasid general (b. 842)
Abu Ahmad Talha ibn Ja'far (Arabic: أبو أحمد طلحة بن جعفر; 29 November 843 – 2 June 891), better known by his laqab as al-Muwaffaq Billah (Arabic: الموفق بالله, lit. 'Blessed of God'), was an Abbasid prince and military leader, who acted as the de facto regent of the Abbasid Caliphate for most of the reign of his brother, Caliph al-Mu'tamid. His stabilization of the internal political scene after the decade-long "Anarchy at Samarra", his successful defence of Iraq against the Saffarids and the suppression of the Zanj Rebellion restored a measure of the Caliphate's former power and began a period of recovery, which culminated in the reign of al-Muwaffaq's own son, the Caliph al-Mu'tadid.
