Many inhabited places in Xanthi Prefecture of Greece had older Greek and non-Greek forms. Most of those names were in use during the multinational environment of the Ottoman Empire, which controlled the region until the Balkan Wars on 1912–1913. Some of the forms were identifiably of Greek origin, others were Turkish and even of Slavic or of more obscure origins. Following the First World War and the Greco-Turkish War which followed, an exchange of population took place between Greece, Yugoslavia, Bulgaria and Turkey (the Treaty of Neuilly between Greece and Bulgaria and the Treaty of Lausanne between Greece and Turkey).
