He had succeeded so far as to establish a dynasty; and his son Garcia Fernández became the next count of Castile as of right. The defects of the hereditary system became at once apparent, for while inheriting his father’s rank, Garcia inherited little of his ability. Unluckily for him, he was the contemporary of the terrible Al Mansûr, the greatest and most formidable of the Moorish race. Castile was ravaged from the Sierra Guadarrama to the sea. Don Sancho, supported by the Moors, revolted against his father, who died from wounds received in battle on the banks of the Douro, in May 995. The unfilial Sancho was at once acknowledged sovereign Count of Castile, but was compelled to pay an annual tribute to the Khalifa of Cordoba. But we find Al Mansûr waging war against him seven years later. It was the great Mohammedan’s last campaign, and Sancho profited by the dismay into which their leader’s mortal sickness plunged the Moslems to expel them from his dominions. Two or three years later we find the envoys of rival Moorish monarchs soliciting the aid of the count of Castile; and in 1009 Sancho paid off old scores by taking and sacking the proud city of the Khalifas. Never had so much richness been seen in barren Castile, when her armies returned laden with booty. ‘He of the good laws,’ as Sancho was styled by his subjects, died in 1021, and was buried in the church of the monastery of San Salvador de Oña, which he had founded. The sisters of his youthful son and successor, Garcia II., were married to the kings of Leon and Navarre; and Garcia went to Leon to seek the hand of King Bermudo’s daughter, and to demand recognition of his title as king of Castile. The poniards of the three sons of the Count de Vela left him a bleeding corpse at the door of the church of San Isidoro, on the 13th May 1029, and put an end to the male line of the house of Fernan González. His destined bride became the wife of Fernando, son of the king of Navarre, who was proclaimed count of Castile, though he enjoyed nothing more than the semblance of sovereignty till his father’s death in 1035. Bermudo of Leon died two years later, and Fernando thus became king of united Leon and Castile--the former in right of his wife, the latter in right of his mother.
