Abd al-Rahman ibn Rustam

Abd al-Rahman ibn Rustum (Arabic: عبد الرحمن ابن رستم; c. 8th century, d. c.784–785) was an Ibadi leader and the first imam associated with the polity later known as the Rustamud Imamate in the Maghreb, whose capital and principal center of rule was established at Tihert (near modern Tiaret, in present-day Algeria).

After building his reputation within the Ibadi networks of Ifriqiya (with formative links to eastern Ibadi scholarship), Abd al-Rahman became a key leader for Ibadi communities seeking autonomy from caliphal authority. Proclaimed imam by Ibadi groups around 776–777 (some chronologies place the decisive phase slightly later), he ruled until his death and was succeeded by his son Abd al-Wahhab, beginning the Rustumid dynasty that lasted until the Fatimid conquest in 909.
