Abderrahman, sultan of Morocco, born in 1778, died in August, 1859. He succeeded to the throne in 1823, on the death of his uncle, Muley Suleiman. At his succession the practice of paying tribute to the Barbary states and Morocco by independent Christian states, as a guarantee against piracy, had not ceased; but Abderrahman was compelled by the Aus-trians in 1828 to abandon the claim. In 1844 the prolonged resistance of Abd-el-Kader to the French invasion in Algeria involved Mo-rocco in war with France, and Mogadore and Tangier were bombarded by a French fleet. The contest was terminated by the battle of Isly, Aug. 14, 1844, in which only Abd-el-Kader's Arabs fought well on the Moslem side. Abderrahman was now compelled to turn his arms upon the Algerian emir, and, having collected a large army, finally drove him beyond the frontiers of Morocco into French captivity. Abderrahman was succeeded by his eldest son, Sidi Mohammed, born in 1803.
