According to monk and biographer
Teodosije the Hilandarian, King Radoslav was a good ruler at first, but fell under the influence of his wife,
Queen Anna, daughter of the
Epirote ruler
Theodore Komnenos Doukas (1216–1230). The Serbian nobility most likely disliked Radoslav due to this Greek influence. Radoslav was probably safe from domestic rebellion as long as Theodore remained strong. In 1230, Theodore was
defeated and captured by Emperor
Ivan Asen II of Bulgaria, after which Radoslav's position seems to have weakened; some of his nobility revolted in the
autumn of 1233. Teodosije said that the nobility no longer supported Radoslav, and instead supported Vladislav. Radoslav and his wife fled to Dubrovnik in 1233. He was unable to regain the kingdom, but eventually returned as a monk. There are indications that Radoslav organized rebellions against Vladislav, and that he thought that he would regain the throne. This is evident from a document dated February 4, 1234, which promised Ragusa trading privileges once Radoslav had returned to Serbia and become king again. Because of this, Vladislav began threatening Ragusa, which then turned to Ban
Matej Ninoslav of Bosnia for help. The revolt against Vladislav was unsuccessful, and Radoslav joined the court of Epirote ruler Manuel in
Dyrrhachium. Archbishop Sava tried to stop the conflict. He most likely sympathized with Radoslav, as he was the legitimate ruler. However, to stop the conflict, which could become more serious, Vladislav was
crowned king upon Radoslav's departure from Serbia. Thanks to Sava, Vladislav married the daughter of Ivan Asen II. Sava then abdicated in favour of his apprentice,
Arsenije, at the end of 1233. Radoslav contacted Archbishop Sava, who welcomed him back to Serbia. Radoslav took monastic vows, and took the name
Jovan (John). According to Teodosije, Sava did this to protect Radoslav from Vladislav. In 1235, while visiting the Bulgarian court, Sava died while on his way home from a pilgrimage to the
Holy Land. He was respectfully buried at the
Holy Forty Martyrs Church in
Tarnovo. Sava's body was returned to Serbia after a series of requests, and was then buried in the
Mileševa monastery, built by Vladislav in 1234. Vladislav intended Mileševa to be his own burial place. Sava was canonized, and his relics were considered miraculous; his cult remained throughout the
Middle Ages and the
Ottoman occupation. After Radoslav had returned to Serbia as a monk, the details of his relationship with Vladislav are not fully known, but he likely did not disturb Vladislav. Some even believe that Radoslav received a part of Serbia to administrate. In any case, Radoslav lived the rest of his life in peace. ==Foreign policy==
