1. Stefan Radoslav, known as Stephanos Doukas, was the King of Serbia, from 1228 to 1233.
Stefan Radoslav reportedly had two sisters, the first of whom, Komnena Nemanjic married first Dhimiter Progoni, and secondly the Greco-Albanian lord Gregorios Kamonas, while the second married the sebastokrator Alexander Asen, whom George Acropolites identifies as a son of Tsar Ivan Asen I It is uncertain if his mother was Maria or Helena, respectively the first and second wife of Ivan Asen I Alexander was the father of Kaliman II of Bulgaria.
The senior Stefan was evidently unafraid of a military confrontation with his former father-in-law which could have occurred in retaliation for his actions.
Stefan Radoslav Nemanjic had ongoing border disputes with both Vukan Nemanjic and Emeric of Hungary, though outright war had not started yet.
The Byzantines had failed to provide him with any military support and Stefan Radoslav had apparently despaired of any help arriving from that direction.
Stefan Radoslav had reasons to distance himself from the Byzantines and the Eastern Orthodox Church associated with them.
Stefan Radoslav's father was later remarried to Anna Dandolo, a daughter of Ranier Dandolo and granddaughter of Enrico Dandolo, Doge of Venice.
Stefan Radoslav had one paternal half-brother from this marriage, Stefan Uros I His mother would proceed to marry secondly to Alexios V Doukas and thirdly to Leo Sgouros, ruler of Nafplion.
However, there were no known children by either marriage, thus Stefan Radoslav consequently had no maternal half-siblings.
Orbin then claims that Stefan Radoslav died and Nemanjic granted his area to Andrew.
Orbin continues his account but Stefan Radoslav is not mentioned again.
Stefan Radoslav acquired control over areas of Zachlumia northwest of the Neretva.
Stefan Radoslav could have either taken advantage of Andrew's troops already withdrawing or using his own forces to drive them out.
Stefan Radoslav suggests it could be as late as 1216, just a year before Nemanjic was declared a King by Pope Honorius III.
Fine mentions Stefan Radoslav acting as governor of the Principality of Zeta for part the reign of his father.
King Stefan Radoslav the First-Crowned, who had become ill, took monastic vows and died in 1227.
Stefan Radoslav who was the eldest son succeeded as King, crowned at Zica by Archbishop Sava, his uncle and the first Archbishop of the autocephalous Serbian Orthodox Church.
Stefan Radoslav was most likely not beloved by the Serbian nobility due to this Greek influence.
Stefan Radoslav used his Greek name, Stephanos Doukas, on his coinage, in several Greek documents and even once in his signature.
Stefan Radoslav was probably safe from domestic rebellion as long as his father-in-law Theodore remained strong.
In 1230 Theodore was defeated and captured by Bulgarian Emperor Ivan Asen II, after which Stefan Radoslav's position seems to have weakened; some of his nobility revolted in autumn 1233.
Serbian medieval biographers noted that the nobility had left the support of Stefan Radoslav and stood itself behind the younger Vladislav.
