In 1085 the Cid, a Castilian chieftain, born at Búrgos, and famous in poetry, romance, and war, seized Toledo, and overran Valencia; in 1118 Alfonso of Aragon wrested Saragossa from the Moors. Portugal, hitherto a province of Castile, assumed the title of kingdom in 1139. Finally the four kingdoms of the north, together with Portugal, formed a league against the Infidels, and in a great battle fought in the Sierra Morena, near Tolosa, in 1212, Mahometan power in Spain was effectually broken. In this decisive engagement the Christian confederates were commanded by Alfonso III. of Castile, who never rested till the followers of the Prophet were driven from the central plateau. To the kingdom of Castile, Ferdinand III., 1217-1252, annexed Jaen, Córdova, and Seville, which with difficulty were held by his son Alfonso X., surnamed the Wise—a better scholar than soldier, as we see. Alfonso XI. was succeeded by Pedro el Cruel, who died in 1369. [Sidenote: SPAIN'S GRANDEUR.] A succession of singularly brilliant events, culminating in the empire of Charles V., brought Spain, at the beginning of the sixteenth century, to the front rank among European powers. The marriage of Ferdinand and Isabella, which in 1479 united the crowns of Aragon and Castile; the conquest of Granada in 1492, terminating eight centuries of almost continuous warfare; the discovery of America the same year; the annexation of Naples in 1503, and of Navarre in 1512, after the union of Spain and the Netherlands in the marriage of Juana, daughter of Ferdinand and Isabella, with Philip the Fair, son of the Emperor Maximilian I., and father of Charles V., all coming in quick succession, form a train of important incidents unparalleled in the history of nations. Before the death of Philip II. in 1598, the empire of Spain extended to every part of the globe—Portugal, conquered by the duke of Alva in 1580; Sicily and Sardinia, Artois and Franche Comté, the Balearic and Canary islands; in Africa—Melilla, Ceuta, Oran, and Tunis; in Asia—the Moluccas and the Philippine Islands, together with several settlements elsewhere; beside a large part of the two Americas, which alone comprised about one fifth of the world.
