Abd al-Aziz IV, 1880-1943, sultan of Morocco (1894-1908), son of Hassan. His weak control was evident after the death (c.1900) of the regent Ba Ahmed. His submissiveness to foreign influence, his indulgence in European luxuries (which Muslims considered unbefitting his position as religious leader), and his reorganization of the tax system led to widespread unrest. The Franco-British agreement of 1904 furnished a pretext for French demands that led in 1906 to the Algeciras Conference (see Morocco). Moroccan disapproval of the settlement led to revolt; Abd al-Aziz was deposed (1908) by his brother Abd al-Hafiz.
