In the later 1350s, the Ottoman expansion into Thrace began, under the prince Süleyman Pasha. After Kantakouzenos' abdication in 1354, Süleyman conquered many cities "up to Chariopolis", establishing the first Ottoman province on European soil. If Chariopolis was not conquered in this first wave, then it definitely fell to Süleyman between 1359 and 1362. As a result of the Ottoman conquest, by the end of the 14th century, the bishopric became a titular see, and vanishes completely in the 15th century. The Catholic Church still lists Chariopolis as a titular see, with eight incumbents between 1713 and 1970.
