ing personally many of the actors in that struggle, it was fitting that he should become, as he did, the annalist of those stirring times.
3. Spain.
The Beginnings of Spain.—When, in the eighth century, the Saracens swept like a wave over Spain, the mountains of Asturia, in the northwest corner of the peninsula, afforded a refuge for the most resolute of the Christian chiefs who refused to submit their necks to the Moslem yoke. These brave and hardy warriors not only successfully defended the hilly districts that formed their retreat, but gradually pushed back the invaders, and regained control of a portion of the fields and cities that had been lost. This work of reconquest was greatly furthered by Charlemagne, who, it will be recalled, drove the Saracens out of all the northeastern portion of the country as far south as the Ebro, and made the subjugated district a province of his great empire, under the name of the Spanish March.
By the opening of the eleventh century several little Christian states, among which we must notice the names of Castile and Aragon, because of the prominent part they were to play in later history, had been established upon the ground thus recovered or always maintained. Castile was at first simply " a line of castles " against the Moors, whence its name.
Union of Castile and Aragon (1479).—For several centuries the princes of the little states to which we have referred kept up an incessant warfare with their Mohammedan neighbors; owing however to dissensions among themselves, they were unable to combine in any effective way for the reconquest of their ancient possessions. But the marriage, in 1469, of Ferdinand, prince of Aragon, to Isabella, princess of Castile, paved the way for the union a little later of these two leading states. Thus the quarrels of these rival principalities were composed, and they were now free to employ their united strength in effecting what the Christian princes amidst all their contentions had never lost sight of,—the expulsion of the Moors from the peninsula.
