The Vojislavljević (, pl. Vojislavljevići / Војислављевићи) was a Serbian medieval dynasty, named after archon Stefan Vojislav, who wrested the polities of Duklja, Travunia, Zahumlje, inner Serbia and Bosnia from the Byzantines in the mid-11th century. His successors, kings Mihailo I Vojislavljević (d. 1081) and Constantine Bodin (d. 1101) expanded and consolidated the state. During the 12th century, the main line of the Vojislavljević family was ousted by their cadet branch, the Vukanović (which became the Nemanjić dynasty), in the late 12th century. History Background Stefan Vojislav Stefan Vojislav, the progenitor of the dynasty, was a nobleman in Byzantine service who had the titles of archon, and toparch of the Dalmatian kastra of Zeta and Ston. In 1034 he led an unsuccessful revolt that resulted in his incarceration at Constantinople, he however, managed to escape and return, this time successfully gaining independence of his statelet, which he would rule as Prince of the Serbs, a title signifying supreme leadership among the Serbs. The contemporary Byzantine writers call him a Serb. The Chronicle of the Priest of Duklja, a later, more dubious source, calls him a cousin to previous ruler Jovan Vladimir (r. 990–1016). Mihailo I Mihailo I became Prince in 1046. He restored independence and maintained it from the Byzantine Empire. He sought closer relations with other great powers, such as the Pope and the Normans. Mihailo installed his son Petrislav as Prince of Rascia. After the aborted rebellion in Bulgaria, the military governor of Dyrrhachium, Nicephorus Bryennius, restored Byzantine rule to Rascia in 1073. Mihailo reportedly received royal insignia in 1077 from Pope Gregory VII, although this is still a matter of debate. An image of King Mihajlo with his crown is still found in the Church of St. Michael in Ston, a town in the Pelješac peninsula (in present-day Croatia). Mihajlo's rule ended in 1081. Constantine Bodin His successor was his son Constantin Bodin, who ruled from 1081 to 1101. Bodin fought Byzantium and Normans further to the south, and took the town of Dyrrachium. He established vassal states in Bosnia (under Stefan) and Raška (under Vukan and Marko), which recognized his supremacy. Vukan and Marko, the new princes of Raška were probably sons of the aforementioned Petrislav. Vukan (1083–1115) was the Grand Župan while Marko headed administration of a part of the land. The Byzantine Emperor Alexios later forced Vukan to acknowledge Byzantine suzerainty in 1094. After
