Roman Danylovich

Roman Danylovich (b. ca 1230, d. ca 1261), Prince of Black Ruthenia (Navahradak) 1254–1258, Prince of Slonim?.

He was born as a younger son of Danylo of Halych, a powerful prince of lands east from Poland and later king of those regions, which was most of the times called Volhynia or Ruthenia (roughly, near modern Belarus and Ukraine).

In 1252 he was married to Gertrude, Duchess of Austria as her third husband. He, in Western Europe, participated in her attempts to get the power in her duchy, under rivaling claimants. However, already next year they ended up in divorce and Roman returned to Ruthenia where he was 1254-58 Prince of Navahradak.
