Ulv Galiciefarer (also known as Galicieulv (Galiciwolf) c. 1010), aka Jarl Galizur-Ulfric was a Danish jarl, a Viking chieftain who became famous for his raids, looting and pillaging the lands of Galicia in the early eleventh century, perhaps in 1028 or 1048, during the reign of Bermudo III and Ferdinand I of Leon. According to Saxo Grammaticus and the Knýtlinga saga, Galicieulv was grandfather of Boedil Thurgotsdatter, the wife of Eric I of Denmark.
The Knýtlinga saga is one of the main sources on his life. It states that he left "bravely with his westward to conquer Jakobsland" (the land of Santiago de Compostela). Most likely he was devoted to raiding and plundering with relatively little opposition. Some legends claim that he served as a mercenary for galician count Rodrigo Romániz, in the assault on Labio Castle, near present-day Lugo, over the riots against Bermudo III. Ulf also helped Romariz against the Basque, achieving victory. The raids continued until Ulf was expelled from Cresconio troops, but not before looting Redondela monastic communities as on the islands of San Simon, Cies and Toralla enclosures. After his expulsion, the Viking attacks on Galicia fell sharply.
According to Saxo Grammaticus, Úlfr (Old Norse: Wolf) was of noble family. It is speculated that he was the son of Ulf the Earl of Swedish origin who settled in Denmark. His father married Astrid, daughter of King Sweyn I of Denmark. The genealogies seem to relate Ulf to the Danish royal family, specifically Lavard lineage. He married when young with Bothild Håkonsdatter (b. 1014), daughter of the Earl of Lade Håkon Eiriksson. They had a son, Thrugot Fagrskinna Ulfsen (n. 1032, nicknamed pale skin although apparently his skin was dark). Trugot would become Count Palatine (Leibhauptman des Königs) Trugot's daughter, Bothild Thorgunnsdatter (Bothilda, 1068-1134) married the Danish King Eric I of Denmark. The couple died on a pilgrimage to the Holy Land. However, his son, Prince Lavard became Duke of Schleswig.
