Феодор Комнин Дука
According to biographer and monk Theodosius, Radoslav was a good ruler at first, but then fell under the influence of his wife, who was the daughter of the ruler of Epirus and Thessalonica, Theodore Komnenos Doukas (r. 1215–1230). Radoslav was most likely not beloved by the Serbian nobility due to this Greek influence. Radoslav used his Greek name, Stephanos Doukas, on his coinage, in several Greek documents and even once in his signature.
