Christianization of Serbs in the context of "First among equals"

The medieval period in the history of Serbia began in the 6th century with the Slavic migrations to the Balkans, and lasted until the Ottoman conquest of Serbian lands in the second half of the 15th century. The period is also extended to 1537, when Pavle Bakić, the last titular Despot of Serbia in Hungarian exile, fell in the Battle of Gorjani.

At the time of settling, Serbs were already transitioning from a tribal community into a feudal society. The first Serbian state with established political identity was founded by prince Vlastimir in the mid-9th century. It was followed by other Serbian proto states, unstable due to the constant clashes with the Bulgarians, Hungarians and Byzantines, and by the conflict between Rome and Constantinople regarding the Christianization with the Byzantines getting the upper hand in the 9th century.
