Read story from Western Bosnia, recorded among Serbs from Livno county (with Serb and Croat population) about Cyril and Methodius, who lived together (in the community).
However, they split. After division, Cyril is Orthodox and Methodius – Catholic. Since then goes and strife between Serbs and Croats on religious grounds. Until then, Cyril and Method shared same religion, and Serbs and Croats were one people.
In fact, Methodius separated from Cyril, so Cyril remained in "right faith" (ie. Orthodox).
Method took Croats, while with Cyril stay Serbs.
