Stefan Radoslav of Serbia

Stefan Radoslav (; 1192 – after 1235), also known as Stephanos Doukas, was the King of Serbia, from 1228 to 1233. Family Stefan was the eldest son of Stefan Nemanjić (r. 1196–1228), by his first wife Eudokia Angelina, daughter of Byzantine Emperor Alexios III Angelos (r. 1195–1203) and Euphrosyne Doukaina Kamaterina. He reportedly had two unnamed sisters, the first of whom married first the Albanian prince Dhimitër 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 of Bulgaria (r. 1189–96). 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 (r. 1256). According to the historian John Van Antwerp Fine, Jr., Eudokia was repudiated on grounds of adultery in 1200–01. Fine summarizes a passage of Niketas Choniates to state "She left on foot with only the clothes on her back". Eudokia sought refuge with her brother-in-law Vukan Nemanjić, Prince of Zeta. Vukan provided her with hospitality for a while and then arranged for her transportation to Durrës, where she boarded a Byzantine ship heading for Constantinople and returned safely to her father. This indicates Stefan Radoslav was born either in the 1190s or the early 1200s (decade). Fine considers the treatment of Eudokia to be an indication of a decline in the prestige the Byzantine Empire held at the time. 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. The alliance with the Empire had apparently outlived its use to the Serbian rulers. Stefan Nemanjić had ongoing border disputes with both Vukan Nemanjić and Emeric of Hungary, though outright war had not started yet. The Byzantines had failed to provide him with any military support and Stefan had apparently despaired of any help arriving from that direction. At the same time the senior Stefan was negotiating submitting himself and his subjects to the Roman Catholic Church in exchange for Pope Innocent III declaring him a King. He had reasons to distance himself from the Byzantines and the Eastern Orthodox Church associated with them.
