Jaun Zuria
Jaun Zuria ("The White Lord") is the mythical first Lord of Biscay. According to the legend, he was born from a Scottish princess that had been visited by god Sugaar in the village of Mundaka. The 15th century warlord Lope García de Salázar adapted a history from the Libro dos Linhagems by Pedro Alfonso, making Jaun Zuria a noble elected by the Biscayne people to lead them against a Leonese army in the mythical battle of Arrigorriaga.
There is nothing historical in this legend, as the Lordship of Biscay was created by the Castilians after they conquered the territory to Navarre in 1200. Surely the legend was created by the members of this dynasty to justify their right to the title, creating the false story that Biscay had been independent and not just part of Navarre, as actually was the case.
