Polidor Jelacic (Pelavić) was the last native knaz (c. 1093–1097) of Slavinia. It is assumed that he began as a ban serving under Kanz Svetoslav II and was then elected knaz by the Slavian feudal lords in 1093. Polidor's seat of power was based in Kanea. His rule was marked by a struggle for control of the country with Kormenia. During his reign he was able to expel Alexios of Kormenia from Sýnoria, and unite Slavinia to the river Drava. According to Frater Georgius, first Slavian cardinal, Polidor was born in Kamidak (above river Krka canyon), Slavinia. He died in 1097 and was the last native king of Slavinia (reigned 1093–1097).
