Mam(O)un, al, Abbas-Abdallah
Mam(O)Un, Al, Abbas-Abdallah,
a celebrated Mussulman ruler, was born at Bagdad in A.D. 786; was the son of Haroun-al-Raschid; and ascended the throne as the seventh Abasside caliph in 813. By his determintation to enforce the heretical doctrine that the Koran was created and not eternal, he became very unpopular among the Moslem doctors and gave strength to the house of Ali. (See MOHAMMEDANISM); (See MOHAMMEDAN SECTS). Mamoun was a patron of science and literature, and is praised by Eastern writers for his talents and liberality. His capital, Bagdad, was in his day the great center of the world of learning and science. — He died in 833. See Weil, Gesch. d. Chalifen, II, chap. 7; Hammer-Purgstall, Literaturgesch. d. Araber.
