Роман Мстиславич
The Romanovych branch of the dynasty ruled central and western Rus'. These territories were unified by Roman the Great and his son Danylo, who was later crowned king of Galicia–Volhynia. After the line's extinction, the kingdom was absorbed by Poland and Lithuania, and the title of its king eventually passed to the ruler of Austro-Hungary. Continuous Rurikid sovereignty from the ninth century to the fourteenth represents part of Ukraine's historical process. In Ukrainian historiography, Rus' civilization—sometimes called Ukraine-Rus"'—"is not considered to have ended in 1240, but merely to have shifted its centre slightly westward.
