The moment Henry became aware of this marriage, the civil struggle recommenced. In vain the firm, yet pacific Archbishop of Toledo recalled the consent he had given, and proved that the union not only secured the after-glory of Spain, but Henry's present undisturbed possession of his throne. Urged on by his wife, and his intriguing favorite, the Marquis of Villena, who was for ever changing sides, he published a manifesto, in which he declared on oath that he believed Joanna to be his daughter, and proclaimed her heiress of Castile. Ferdinand and Isabella instantly raised an array, regardless of the forces of Portugal (to whose monarch Joanna had been betrothed), who were rapidly advancing to the assistance of Henry. Ere, however, war had regularly commenced, a brief respite was obtained by the death of Henry, and instantly and unanimously Isabella was proclaimed Queen of Leon and Castile. Peace, however, was not instantly regained; the King of Portugal married Joanna, and resolved on defending her rights. Some skirmishing took place, and at length a long-sustained conflict near Fero decided the point--Ferdinand and the Castilians were victorious; the King of Portugal made an honorable retreat to his own frontiers, and the Marquis of Villena, the head of the malcontents, and by many supposed to be the real father of Joanna, submitted to Isabella. Peace thus dawned for Castile; but it was not till three years afterwards, when Ferdinand had triumphed over the enemies of Arragon, and succeeded his father as Sovereign of that kingdom, that any vigorous measures could be taken for the restoration of internal order. The petty Sovereignties of the Peninsular, with the sole exception of the mountainous district of Navarre, and the Moorish territories in the south, were now all united; and it was the sagacious ambition of Ferdinand and Isabella to render Spain as important in the scale of kingdoms as any other European territory; and to do this, they knew, demanded as firm a control over their own subjects, as the subjection of still harassing foes.
