Bosnia, Zahumlje and Rascia never were incorporated into an integrated state with Duklja. Petrislav was the last son of Mihailo I and his Greek second wife. Mihailo I conquered Rascia from the Byzantines between 1060 and 1074.
He appointed Petrislav as Prince of Rascia.
Mihailo I died in 1081, and Constantine Bodin succeeded as Prince. Constantine Bodin ruled unchallengedly.
Each principality had its own nobility and institutions, simply requiring a member of the royal family to rule as Prince or Duke.
