DEMOTICA, or Dimotica, a town of European Turkey, in the vilayet of Adrianople; on the Maritza valley branch of the Constantinople-Salonica railway, about 35 m. S. of Adrianople. Pop. (1905) about 10,000. Demotica is built at the foot of a conical hill on the left bank of the river Kizildeli, near its junction with the Maritza. It was formerly the seat of a Greek archbishop, and besides the ancient citadel and palace on the summit of the hill contains several Greek churches, mosques and public baths. In the middle ages, when it was named Didymotichos, it was one of the principal marts of Thrace; in modern times it has regained something of its commercial importance, and exports pottery, linen, silk and grain. These goods are sent to Dédéagatch for shipment. Demotica was the birthplace of the Turkish sultan Bayezid I. (1347); after the battle of Poltava, Charles XII. of Sweden resided here from February 1713 to October 1714.
