After this fateful battle on the Carrion, in which Bermudo fell, Ferdinand, who had taken Bermudo’s sister to wife, seized upon the whole of Leon and its dependencies and united them with the rest of his dominions to form the kingdom of Castile. His solemn coronation at Leon ushered in a new epoch in the history of Christian Spain. To pacify the Leonese, who were profoundly aggrieved at the loss of their supremacy, he caused an assembly of the estates to be held at Coyanza, and there confirmed all the civil and ecclesiastical privileges and liberties which had come down to them from earlier times, and added others. At the same time he augmented the defensive armaments of his dominions, with the twofold object of repressing rebellion and making war upon the Saracens. His elder brother, Garcia, cast envious glances at the flourishing neighbour country, which rose steadily to greater heights of prosperity and power under Ferdinand’s wise governance. He was mortified that his hereditary kingdom of Navarre should be ousted from the dominant position it had taken under his great father. He therefore laid snares in his brother’s way and embarrassed his dominion by perpetual intrigues till at length a fratricidal war broke out between them. The hatred he bore his brother led Garcia to conclude an alliance with the emir of Saragossa and Tudela. But the battle of Atapuerca (1054), not far from Burgos, decided the struggle in Ferdinand’s favour; Garcia was slain by a lance-thrust, the Navarrese were routed, and most of their Moorish auxiliaries killed or taken prisoners. Ferdinand then added the district on the right bank of the Ebro to his own dominions, and left the rest of the kingdom to the late king’s son, Sancho III. Having thus tranquillised his own kingdom and assured its safety, he endeavoured to extend it southwards by making war upon the infidels. He destroyed the fortresses in the northern provinces of what is now the kingdom of Portugal, crossed the Douro, and took Lamego, Viseu, and other fortified towns, under whose walls Christian and Moslem had so often measured their strength in days gone by. These successes inflamed the Castilians with martial ardour and religious enthusiasm and made them eager for fresh ventures. Having first secured the consent of his knights and nobles in an assembly of the estates, the king conquered a chain of fortified towns on the eastern frontier of Castile which had long served the enemy as a _point d’appui_, and then pressed forward into the heart of the Moorish provinces. He laid the country waste, and spread terror as far as Andalusia. The aged ruler of Seville purchased peace with rich gifts, among which were the relics of St. Isidore, which Ferdinand buried with great pomp at Leon in the church he had built and dedicated to the saint.
