The Serbs were initially under the jurisdiction of the Archbishopric of Ohrid, under the tutelage of the Ecumenical Patriarch of Constantinople.
Rastko Nemanjić, the son of Stefan Nemanja, ruled as Grand Prince of Hum 1190-1192, previously held by Grand Prince Miroslav.
In the autumn of 1192 (or shortly thereafter)
Rastko joined Russian monks and traveled to Mount Athos where he took monastic vows and spent several years.
In 1195, his father joined him, and together they founded the Chilandar, as the base of Serbian religion.
Rastko's father died in Hilandar on 13 February 1199; he was later  canonised, as Saint Simeon.
Rastko built a church and cell at Karyes, where he stayed for some years, becoming a Hieromonk, then an Archimandrite in 1201.
He writes the Karyes Typicon during his stay there.

He returned to Serbia in 1207, taking the remains of his father with him, which he relocates to the Studenica monastery, after reconciling Stefan II with Vukan, who had earlier been in a succession feud.
Stefan II asked him to remain in Serbia with his clerics.
He founded several churches and monasteries, including the Žiča monastery.
