ADIYAMAN

formerly Hsnmansur, Arabic Hisn Mansur, city located in a valley of southeastern Turkey. Founded in the 8th century by the Umayyad Arabs near the site of ancient Perre, Hisn Mansur was later fortified by Caliph Harun ar-Rashid and became the chief town of the area, replacing Perre. Ruled successively by the Byzantines, Seljuq Turks, and the Turkmen Dulkadir dynasty after the Arabs, it was incorporated into the Ottoman Empire near the end of the 14th century. Under the Turkish republic, it was renamed Adiyaman in 1926. The ruins of Perre are just to the north. The city is a local market for the agricultural products of the area. The region around Adiyaman contains mountains and plateaus drained by the Euphrates River and its tributaries. Many of the residents in the region are Kurds. Products include cereals, cotton, tobacco, pistachio nuts, and grapes. Pop. (1990) 100,045.
