followed by a Byzantine reconquest. Later on, the Strumica region was conquered by Bulgarian Khan Presian (836–852). The Strumica region remained part of the Bulgarian state throughout a period of more than 150 years right up until 1014, when it was retaken by the Byzantines. In the 11th century, written sources begin to refer to the town with its Slavic name as Strumica. In 1016, Byzantine commander David Arianites captured the city from the Bulgarians. By the end of the 12th century, the Byzantine central power had weakened and, as a result, many local lords broke away and became independent. Initially, the leader of the Vlachs and Bulgarians in eastern Macedonia Dobromir Chrysos (1185–1202) and later the Bulgarian sebastokrator and a member of the Asen dynasty in Veliko Tarnovo Strez (1208–1214) held the region, which became part of the Bulgarian kingdom in 1202. In the second half of the 13th century the city was recovered by the Byzantine Empire until the Serbian Kingdom conquered the region in the 14th century. Serbian magnate Hrelja ruled Strumica and the nearby region until 1334, when it was put under the direct rule of Serbian King Stefan Dušan who continued his conquest to the south. During the Fall of the Serbian Empire, the Strumica region was first ruled by Uglješa, the brother of magnate Vukašin. Strumica itself was then governed by Dabiživ Spandulj, who served the Dejanović brothers. The Ottoman Empire finally conquered Strumica in 1383.

Nomads and livestock breeders of Turkic origin were settled, which altered the general look of the city making it more oriental. According to the census of 1519, Strumica had a population of 2,780, of which 1,450 were Christians and 1,330 were Muslims. These were times when conversion to Islam was at its peak in the region, which accounts for the increased number of Muslims (2,200) compared to Christians (1,230) according to the census of 1570. In the 17th century, it became seat of a kadiluk. At about this time, Strumica was visited by the Ottoman travel writers Haji Kalfa (1665) and Evliya Çelebi (1670), who gave a description of the city and all its Islamic buildings.
