Abd ar-Rahman

Abd ar-Rahman, 1778-1859, sultan of Morocco (1822-59). He sought, unsuccessfully, to take advantage of the overthrow of Turkish rule in Algeria in order to extend his territory. Later he allied himself with the emir, Abd al-Kader, but after their defeat at Isly (1844), he made peace with France and refused the emir further asylum in Morocco. Abd ar-Rahman was at various times involved in difficulties with Austria, Spain, and Great Britain.
