Having renewed his acknowledgement of Byzantine overlordship, he soon sided with their enemies, the Normans, which resulted in a Byzantine invasion and his capture.

Kočopar, Bodin's first cousin once removed, travelled from Dyrrhachium to Rascia, forging an alliance with Vukan. This alliance would prove worthy in their successful invasion of Duklja in 1102. The battle that ensued at the Morača led to the overthrow of Dobroslav II and the coronation of Kočapar to the throne. Dobroslav was subsequently banished to Rascia and a large part of Dalmatia was pillaged in the process. Vukan gave Kočapar Duklja as a fief.

By 1186, Byzantine possessions in Upper Dalmatia were overrun by Stefan Nemanja, who also imposed his rule over Duklja.
