Noureddin (Malek al-Adel Nun ed-Din Maiimoud), a Mohammedan ruler of Syria and Egypt, born in Damascus about 1116, died there in 1173 or 1174. He succeeded his father Zen-ghi, of the Atabek dynasty, in 1145, and made Aleppo his capital. Soon afterward he expelled the Christians from Edessa, demolished the walls, and massacred the inhabitants. Subsequently he invaded Antioch, and defeated and slew Prince Raymond. He was routed in the following year by Jocelin de Courtenay, but afterward captured that leader. The whole of northern Syria now fell into his hands. In 1154 the Damascenes, dreading an attack from Baldwin III., king of Jerusalem, sought the protection of Noureddin, who in 1156 entered Damascus, rebuilt and adorned it, and made it his capital. In 1159 the Greek emperor, Manuel Comnenus, formed an alliance with the Franks of Antioch against him, but was bought off, and Noureddin defeated and captured Reginald de Chatillon, prince of Antioch. He now sent to Egypt an army under Shir-kuh to support the emir Shawer against his rival Ed-Dargam. Shawer, having gained the throne, formed an alliance with the Franks and drove Noureddin's troops out of Egypt. In a second expedition Skirkuh defeated the Franks, put Shawer to death, and ruled Egypt as the lieutenant of Noureddin, who received from the caliph of Bagdad the title of sultan and the direct investiture of Syria and Egypt. Moslems and Christians equallv extol his character.
