As a result of Babai revolt, in 1261, one of the Turkoman dervish Sari Saltuk was forced to take refuge in the Byzantine Empire, alongside 40 Turkoman clans. He was settled in Dobruja, whence he entered the service of the powerful Muslim Mongol emir, Nogai Khan. Sari Saltuk became the hero of an epic, as a dervish and ghazi spreading Islam into Europe.
