King of Ruthenia, King of Rus', King of Galicia and Lodomeria, Lord and Heir of Ruthenian Lands (Latin: Rex Rusiae, Rex Ruthenorum, Rex Galiciae et Lodomeriae, Terrae Russiae Dominus et Heres; Ukrainian: Король Русі, король Галичини і Володимирії, князь і володар Всієї Землі Руської, romanized: Korol Rusi, korol Halychyny i Volodymyrii, kniaz i volodar Vsiiei Zemli Ruskoi) was a title of princes of Galicia and Volhynia, granted by the Pope.
The title was initially issued to the ruling Izyaslavichi of Volhynia.[citation needed] Later the title was passed on to the Romanovichi as rulers of the united Kingdom of Galicia–Volhynia. By the 15th century the title was used as a claim by other royal houses.
