Α. η . 1177. TREATY BETWEEN ALPHONSO AND SANCHO. king of Navarre and Nagara, was the father of king Sancho, who was afterwards slain at Penafiel : he was the father of Sancho, who died without issue when a child, and was succeeded, in Navarre and Nagara, by king Alphonso, his father's kinsman, who took Toledo, as far as the boundaries of Puente la Eeyna and Sangosa : and the said child was succeeded by Sancho, king of Arragon, his father's kinsman, in the remaining portion of Navarre and Pampeluna. The Treaty and Covenants entered into between Alphonse, king of Castille, and SancM, Icing of Navarre. " These are the treaty and covenants which were entered into between Alphonso, king of Castille, and Sancho, king of Navarre, his uncle, for submitting the points in dispute between them to the judgment of the king of England.
