ISMID, or ISNIKMID (anc. Nicomedia), the chief town of the Khoja Ili sanjak of Constantinople, in Asia Minor, situated on rising ground near the head of the gulf of Ismid. The sanjak has an area of 4650 sq. m. and a population of 225,000 (Moslems 131,000). It is an agricultural district, producing cocoons and tobacco, and there are large forests of oak, beech and fir. Near Yalova there are hot mineral springs, much frequented in summer. The town is connected by the lines of the Anatolian railway company with Haidar Pasha, the western terminus, and with Angora, Konia and Smyrna. It contains a fine 16th-century mosque, built by the celebrated architect Sinan. Pop. 20,000 (Moslems 9500, Christians 8000, Jews, 2500). As the seat of a mutessarif, a Greek metropolitan and an Armenian archbishop, Ismid retains somewhat of its ancient dignity, but the material condition of the town is little in keeping with its rank. The head of the gulf of Ismid is gradually silting up. The dockyard was closed in 1879, and the port of Ismid is now at Darinje, 334 m. distant, where the Anatolian Railway Company have established their workshops and have built docks and a quay.
