His feats were repeated and bested by Stefan Vojislav twenty years later, and in 1034 AD, the Bar diocese was elevated to an archdiocese, but a war with Theophilos Erotikos soon followed. Stefan Vojislav's son Mihailo obtained papal support following the East–West Schism of 1054, further weakening Byzantine influence in Dalmatia. Except for Ragusium and the southern third of Dalmatia, Byzantine control collapsed in the 1060s. Constantine Bodin pledged his support for Pope Urban II, which confirmed Bar's status as an archdiocese in 1089 AD, and resulted in a temporary demotion of the Ragusan diocese. By the end of the 11th century, the Kingdom of Hungary took the Kingdom of Croatia's place in controlling the northern Dalmatian hinterland. Duklja remained largely under Byzantine control, with a series of internal conflicts weakening its leaders. Byzantine predominance was restored under Emperor Manuel I Komnenos (r. 1143–1180), but vanished after his death and was replaced by Venetian control. With the rise of Stefan Nemanja, the Nemanjić dynasty took control of the lands in the south of coastal Dalmatia, while nearly all the Dalmatian islands and coastal north-central Dalmatia was under full Venetian control since the 13th century and remained an area of the venetian Stato da Mar until 1797.
