Theodore Stratelates
The town was captured by the forces of Sviatoslav I of Kiev in 969, but two years later it was taken by the Byzantines during the Battle of Dorostolon. It was renamed Theodoropolis, after military saint Theodore Stratelates, who is said to have come to the aid of Emperor John I Tzimiskes during the battle. In 976, Tsar Samuel restored Bulgarian rule in the region until 1001, when it once again became part of the Byzantine Empire.
