Stefan Nemanjić was the second-eldest son of Grand PrinceStefan Nemanja and Anastasija. His older brother and heir apparent, Vukan, ruled over Zeta and the neighbouring provinces (the highest appanage) while his younger brother Rastko (later known as Saint Sava) ruled over Hum.
The Byzantines attacked Serbia in 1191, raiding the banks of the South Morava. Nemanja had a tactical advantage, and began to raid the Byzantine armies. Isaac II Angelos summoned a peace treaty, and the marriage of Nemanja's son Stefan to Eudokia Angelina, the niece of Isaac II, was confirmed. Stefan Nemanjić received the title of sebastokrator.
Conflict over succession
Throughout the 12th century, Serbs were at the center of war events between Byzantium and Hungary for dominance. In such circumstances, Serbs had no chance of gaining independence. Their only chance was to look for an ally on third side.
In 1190, the German Emperor Friedrich Barbarossa drowned in the river Calycadnus. At the same time, Emperor Isaac II Angelos launched a punitive expedition against the Serbs, and Nemanja was defeated in the battle of South Morava. In fact, Constantinople did not want to subdue the Serbs, but to regain Niš and the main road to Belgrade, as well as to make allies of the rebellious Serbs. The peace treaty provided for Stefan Nemanjić, the middle son of the grand zoupan Stefan Nemanja, to marry a Byzantine princess, i.e. niece of the Byzantine emperor.
The concluded peace envisages that the grand zoupan Nemanja will be succeeded by his middle son Stefan, who received the Byzantine title of sebastokrator and the Byzantine princess Eudokia for a wife, and not the firstborn Vukan.
In 1196, at the state assembly near Church of Saints Peter and Paul, Stefan Nemanja abdicated the throne in favor of his middle son Stefan, who became the grand zoupan of Serbia. He left his eldest son Vukan in charge of Zeta, Travunija, Hvosno and Toplica. Nemanja became a monk in his old age and was given the name Simeon. Shortly afterwards, he went to Byzantium, to Mount Athos, where his youngest son Sava had been a monk for some time. They received permission from the Byzantine emperor to rebuild the abandoned Hilandar monastery.

The new Pope Innocent III, who in a letter in 1198 called on the entire West to liberate the Holy Land, was not satisfied with the fact that the Serbs were subordinated to the Patriarch of Constantinople, but wanted to return them to Rome through Vukan. In 1198, the Hungarian dux Andrew conquered Hum (Hercegovina) of grand zoupan Stefan and rebelled against brother king Emeric but did not gain legitimacy from Rome. In any case, the Hungarians became dominant on the eastern Adriatic coast. But Venice, because of its business interests, did not like the eastern coast of the Adriatic to be controlled by the mighty Byzantium or Hungary. Vukan and the Hungarian king Emeric (1196–1204) make an alliance against Stefan, after which a civil war breaks out in Serbia. The action against Stefan was preceded by his letter to the Pope in which he asked for the crown. Around 1200, Stefan expelled his wife Eudokia, a daughter of Alexios III Angelos, who found refuge with Vukan in Zeta. Emeric saw Stefan's move as an open attack on his crown, because in Hungary it was traditionally believed that only it in the region could have primacy with the Roman pope. Stefan lost the conflicts and had to flee the country in 1202 to the ruler of BulgariaKaloyan.[5][6][7]
In the meantime, control of the newly formed crusade army was taken over by the powerful Venetian doge Enrico Dandolo, who, to the surprise of all, including the pope himself, in the Fourth Crusade first sent an attack on Hungarian Zara in 1202, and then on Byzantium, whose capital Constantinople crusaders conquered in April 1204. Stefan uses this situation and in the counter-offensive, with the help of Prince Kaloyan, he returns to the throne in Ras in 1204, while Vukan retreats to Zeta. The fighting between the brothers was stopped in 1205 and relations were established as they were before the outbreak of the conflict. Meanwhile, in November 1204, the Hungarian king Emeric died and the Kaloyan of Bulgaria was crowned for king by the Pope.
Numerous states were created on the ruins of Byzantium, which were almost equal in strength. The Crusaders founded the Kingdom of Thessalonica, the principality of Achaia, the duchy of Athens and Thebes, the duchy of Archipelago or Naxos. They were all under rule of Latin emperor of Constantinople. The remaining Byzantine factions also formed their own successor states on the fringes of the empire, at Niceae and Trebizond in Asia Minor, and at Epiros in west Balkan. Of the newly created Greek states, two gained some stability and survived through this period: Niceae under the Laskaris dynasty, which soon became an empire (1208), and Epiros, which took considerably to rise to same status (1224–27). The two rivals sought to present themselves as lawful successor of Empire of the Romans and to get the upper hand in the struggle for its restoration. Bulgaria was located to the north, and Serbia to the northwest. Serbia's neighbors at the time were Epirus to the south, Bulgaria to the east, and the Hungary to the north and west.
Later rule
After the death of Kaloyan, there was a succession war in Bulgaria. Tsar Boril, the most ambitious of the nobles, took the throne and exiled Alexius Slav, Ivan Asen II and Strez (of the Asen family). Strez, the first cousin or brother of Boril, took refuge in Serbia, and was warmly welcomed at the court of Stefan II.[8][9] Even though Boril requested the extradition of Strez to Bulgaria with gifts and bribes, Stefan II refused. Kaloyan had conquered Belgrade, Braničevo, Niš and Prizren, all of which were claimed by Serbia.[8] At the same time, Boril was unable to take military action against Strez and his Serbian patron, as he had suffered a major defeat at the hands of the Latins at Plovdiv.[9] Stefan went as far as to become a blood brother with Strez, in order to assure him of his continued favor.[8]
Andrija Mirosavljević was entitled to the governance of Hum, as the heir of Miroslav of Hum, the uncle of Stefan II, but the Hum nobles chose his brother Petar as Prince of Hum. Petar exiled Andrija and Miroslav's widow (the sister of Ban Kulin of Bosnia), and Andrija fled to Serbia, to the court of Stefan II. In the meantime, Petar fought successfully with neighbouring Bosnia and Croatia. Stefan sided with Andrija and went to war and secured Hum and Popovo field for Andrija sometime after his accession. Petar was defeated and crossed the Neretva, continuing to rule the west and north of the Neretva, which had in 1203 been briefly occupied by Andrew II of Hungary. Stefan gave the titular and supreme rule of Hum to his son Radoslav, while Andrija held the district of Popovo with the coastal lands of Hum, including Ston. By agreement, when Radoslav died, the lands were bound to Andrija.[10]
Đorđe of Zeta, in order to secure his lands from Stefan, accepted Venetian suzerainty, possibly in 1208. Đorđe may have done this due to tensions between the two, although this must not be the case. Venice, after the Fourth Crusade, tried to exert control of the Dalmatian ports, and managed in 1205 to submit Ragusa – Đorđe submitted to prevent that Venice claimed his ports of southern Dalmatia.[11]
Đorđe promised Venice military aid in case of a revolt by another theoretical Venetian vassal, Dhimitër Progoni, the Prince of Albania andLord of Kruja.[11] This was likely related to the Serbia-Zeta conflict.[11] Stefan II married off his daughter,[11]Komnena, to prince Dhimitër Progoni in 1208.[12] The marriage resulted in close ties and an alliance between Stefan and Dimitri amidst these conflicts.[11][12] Kruja is conquered by Epirote DespotMichael I Komnenos Doukas, and Dimitri is not heard of in any surviving sources.[13][12] After Dhimitër's death, the lands are left to Komnena,[14] who soon married Greek-AlbanianGregorios Kamonas, who took power of Kruja,[15] strengthening relations with Serbia, which had after a Serbian assault on Scutari been weakened.[15][12] Đorđe disappears from sources, and Stefan II controls Zeta by 1216, probably through military action.[11] Stefan either put Zeta under his personal rule, or assigned it to his son Stefan Radoslav. Zeta would from now on have no special status, and would be given to the heir apparent.[11]
Despot Michael I of Epirus conquered Skadar, and tried to press beyond, but was stopped by the Serbs and his murder by one of his servants in 1214 or 1215.[13] He was succeeded by his half-brother Theodore Komnenos Doukas.[13] Theodore took on a policy of aggressive expansion, and allied himself with Stefan II. Stefan Radoslav married Anna Angelina Komnene Doukaina, the daughter of Theodore.[16][17]
Having long wanted to call himself king, Stefan set about procuring a royal crown from the papacy. It is not clear what Stefan promised in regard to the status of the Catholic Church, which had numerous adherents in the western and coastal parts of his realm, but a papal legate finally arrived in 1217 and crowned Stefan. In 1217 Stefan Nemanjić declared his independence from Byzantium and was crowned as king, adopting the title: "Crowned King and Autocrat of all Serbian and coastal lands".[18] The influence of the Catholic Church in Serbia did not last long but angered Serbian clergy. Many opposed Stefan's coronation, with Sava protesting by leaving Serbia and returning to Mount Athos. Later Serbian churchmen were also bothered by Stefan's relations with the papacy; while Stefan and Sava's contemporary Domentian wrote that the coronation was performed by a papal legate, a century later Theodosius the Hilandarian claimed that Stefan was crowned by Sava. The contradiction led some Serbian historians to conclude that Stefan underwent two coronations, first by the legate and in 1219 by Sava, but modern scholars tend to agree that only the former took place.[19][20]
The disagreements surrounding Stefan's coronation were definitively resolved in 2018 by finding evidences that the papal legate never came to Serbia and that Stefan was actually crowned by his brother Sava in 1219.[21][unreliable source]
He built many fortresses including Maglič. At the end of his life, Stefan took the monastic vow under the name Symeon and died soon after. He was canonized as his father was.
