Jaun Zuria (Basque for "the White Lord") is the mythical first Lord and founder of the Lordship of Biscay,[1][2] who defeated the Leonese and Asturian troops in the also-mythical Battle of Padura, in which he chased off the invaders to the Malato Tree, establishing there the borders of Biscay. There are three accounts of its legend, one by the Portuguese count Pedro Barcelos and two by the chronicler Lope García de Salazar.[3] According to the legend, Jaun Zuria had been born from a Scottish or English princess who had been visited by the Basque deity Sugaar in the village of Mundaka.
It has been suggested that Jaun Zuria might have the same origin or be the same mythical figure as Olaf the White, an Irish Viking sea-king from the 9th century.[citation needed]
