The Peninsula was at this time divided among a large number of mutually independent and warring States, Christian and Moslem. The sentiments of loyalty to religion and to country were universally subordinated to those of personal interest; Christians fought under Moorish banners, Moors under Christian. Humanity toward the enemy, loyalty to oaths, were not virtues in the common estimation. Between the Christian States of Leon and Castile great jealousy ruled. Castile had come into being as a border province of the Asturian kingdom, governed by military counts. From the first there seems to have been a spirit of resistance to the overrule of the Asturian kings (later known as kings of Leon). Finally, under its Count Fernan Gonzalez (who died 970), Castile secured its independence. But whether leading a separate political existence, or united with Leon, Castile was ever jealously sensitive of any precedence claimed or exercised by its sister kingdom. Ferdinand I. of Leon-Castile, treating his territorial possessions as personal property,--a policy repeatedly fatal to all advance in Spanish history,--divided them at his death (1005), among his five children. Sancho, the eldest, received Castile, Nahera, and Pampeluna; Alfonso, Leon, and the Asturias; Garcia, Galicia, and that portion of Portugal which had been wrested from the Moors; Urraca received the city of Zamora; and Elvira, Toro. The expected occurred. Sancho made war on his brothers, compelling both to flee to Moorish territories, and wrested Toro from Elvira. Rodrigo Diaz, the Cid, appears first at this period. He is the _alferez, i.e._, the standard-bearer, or commander-in-chief under the King, in Sancho's army. The brother Kings, Sancho and Alfonso, had agreed to submit their dispute to a single combat, the victor to receive the territories of both. Alfonso's Leonese army conquered the Castilian, and relying upon the agreement withdrew to its tents. Rodrigo Diaz was already known as the Campeador, a title won through his having, vanquished in single combat the champion of Sancho of Navarre, and signifying probably one skilled in battle, or champion.
