Volodymyrko Volodarovych[1] (Ukrainian: Володимирко Володарович|Volodymyrko Volodarovych) or Vladimirko Volodarovich (Russian: Владимир Володаревич (Владимирко){{citation needed|date=May 2024; 1104 – February 1153[1]) was a Galician prince (from 1141, according to others from 1144), son of Volodar Rostyslavych.[1]
In 1124, Volodymyrko became the prince of Zvenyhorod and Belz.[1] He failed to take Peremyshl from his brother Rostyslav in 1125–6.[1]
He gradually brought together Peremyshl, Zvenyhorod, Halych and Terebovlia, uniting them into one Principality of Halych. The capital of the principality was established at Halych in 1141 (according to some sources, in 1144), which Vladimirko occupied after the death of his nephew Ivan.
He first failed to unite Halych with the Volyn principality, which was under the rule of Kievan prince Vsevolod II. However, thanks to the alliance with Yuri Dolgorukiy, he was able to defeat Kievan prince Izyaslav Mstislavich.
In alliance with the Byzantine emperor Manuel Comnenus, he led the long struggle against the Kingdom of Hungary, which ended only in 1152, when a peace treaty with the Hungarian king Géza was signed.
He had a son: Yaroslav Osmomysl, prince of Halych.[1]
