Роман Мстиславич
Andrew II, King of Hungary from 1205 to 1235, claimed the title "" ("King of Galicia and Lodomeria") – a Latinised version of the Slavic names Halych and Volodymyr, the major cities of the principality of Halych-Volhynia, which the Hungarians ruled from 1214 to 1221. Halych-Volhynia had cut a swathe as a mighty principality under the rule of Prince Roman the Great (Roman Mstislavich) from 1170 to 1205. After the expulsion of the Hungarians in 1221, Ruthenians took back rule of the area. Roman's son Daniel of Galicia (Prince of Galicia until 1255) was crowned king of Halych-Volhynia in 1253. About 1247 Daniel of Galicia founded Lviv (), named in honour of his son Leo I, who later moved the capital northwestwards from Halych to Lviv in 1272.
