Abu al-Abbas Abdallah ibn Harun al-Rashid (Arabic: ??? ?????? ??? ???? ?? ????? ???????, romanized: Abu al-?Abbas ?Abd Allah ibn Harun ar-Rashid; 14 September 786 – 9 August 833), better known by his regnal name al-Ma'mun (Arabic: ????????, romanized: al-Ma?mun), was an Islamic Golden Age ruler and the seventh Abbasid caliph, who reigned from 813 until his death in 833.
He succeeded his half-brother al-Amin after a civil war, during which the cohesion of the Abbasid Caliphate was weakened by rebellions and the rise of local strongmen; much of his reign was consumed in pacification campaigns.
Well educated and with a considerable interest in scholarship, al-Ma'mun promoted the Translation Movement, the flowering of learning and the sciences in Baghdad, and the publishing of the book now known as "Algebra".
He is also known for supporting the doctrine of Mu'tazilism and the rise of the inquisition (mihna), and for the resumption of large-scale warfare with the Byzantine Empire.
