Yurii II Boleslav
Yurii II Boleslav [Jurij] (Troidenovych), b ca 1306, d 7 April 1340 in Volodymyr-Volynskyi. Last ruler of the Principality of Galicia-Volhynia (1323–40); son of Trojden II of Mazovia and grandson of Yurii Lvovych. He was initially known as Bolesław and raised as a Catholic, but he converted to Orthodoxy, and he ascended to the throne of Volodymyr-Volynskyi principality. He maintained relations with Lithuania (he married Yevfymiia-Ofka, daughter of the grand duke of Lithuania, Gediminas) and the Teutonic Knights, with whom he signed treaties in 1325, 1327, 1334, 1335, and 1337. He was met with hostility by Poland and Hungary, however. Yurii sought to strengthen his rule by supporting towns and burghers, protecting German colonists, and encouraging the influx of foreigners. Under his rule Sianik was granted rights under Magdeburg law. The boyars rebelled against him, and he was poisoned in suspicious circumstances. His death marked the end of the Romanovych dynasty of Galician-Volhynian princes as well as the end of the Princely era of Ukraine.
