Kadir Natho notes that "a net of Circassian settlements enveloped practically all the European part of the Ottoman Empire". Very large numbers of Circassians were settled in Bulgaria. "Istoria Bulgarii" reports that "about 6,000 families were transferred through Burgas and settled in Thrace; 13,000 families-- through Varna and Shumen -- to Silistra and Vidin; 12,000 families to Sofia and Nish. The remainder 10,000 families were distributed in Svishtovsk, Nikipolsk, Oriskhovsk, and other outskirts." There was a chain of Circassian settlements stretching from Dobrudja to the Serbian border, with an additional cluster of 23 settlements in the Kosovo field. Circassians also settled in a few mostly Greek areas, particularly in the southern part of Epirus, Cyprus and one colony at Panderma in the Sea of Marmara.
