Mamun

Mamun, sometimes transliterated Ma'mun, is a masculine given name of Arabic origin. The name means "the faithful" or "the trusted" and has been borne by several figures in Islamic history, most notably the Abbasid caliph al-Ma'mun.

Al-Ma'mun (c. 786–833), fully Abu Musa Muhammad ibn Harun al-Rashid, was the seventh Abbasid caliph, ruling from 813 to 833. He is known for his role in ending a dynastic conflict with his brother al-Amin and for consolidating the Abbasid state in the eastern provinces of Khurasan and Transoxiana. He supported scientific and literary advances, contributing to the growth of Baghdad's House of Wisdom as a center of translation and research. He sponsored scholars in astronomy, mathematics, and medicine, and promoted the translation of Greek medical and philosophical texts into Arabic.

His reign also saw the Mihna, an inquisition over the nature of the Qur'an, which attempted to enforce the view that the Qur'an was created; this policy alienated many scholars but reflected the caliph's use of theology to unify the state. The Mihna policy continued beyond his reign and was not permanently resolved until the mid-9th century.

The name Mamun is used in various Muslim-majority regions, with spellings including Ma'mun, Mamun, and Mamoun. It remains a common given name in Arabic-speaking communities and in countries influenced by Islamic culture.
