By the mid-10th century, an Archbishopric of Dubrovnik seceded from Split and included Kotor, Zachlumia (Bishopric of Ston) and Travunija (Bishopric of Trebinje). In the second half of the 10th century the Bishopric of Duklja was mentioned, along with the bishoprics in the maritime cities of Bar, Scutari, Drivast, Pilot in the "župa" of the same name, and Gradac. Though their previous religious affiliation is not known, at this time they were all subordinated to the Metropolis of Dyrrhachium of the Patriarchate of Constantinople.
