The King of Granada, at the time the marriage of Ferdinand and Isabella united the thrones of Aragon and Castile, was one Muley Aben Hassan, a descendant in direct line of the founder of the Alhambra, and when he succeeded his father, Ismael, he found himself ruler over no less than fourteen fortified cities and nearly one hundred towns, as well as many castled hamlets and villages. This fierce warrior, taking account of his vast possessions, refused longer to pay tribute to the Castilian sovereigns, and in the year 1478 a noble knight, Don Juan de Vara, was sent to Granada to demand it. He was admitted, with his retinue of cavaliers, and found King Muley Hassan seated on his royal divan, within the Alhambra, in the spacious Hall of the Ambassadors. He was received with courtesy, but when he named his errand Muley Hassan haughtily replied: “Tell your sovereigns that the Kings of Granada who used to pay tribute in money to the Castilian crown are dead! Our mint at present coins nothing but blades of scimitars and heads of lances!” Now, the name of Granada signifies in Arabic a pomegranate; and when King Ferdinand received this insolent answer from the Moor he quietly replied, “It is well; I will pluck the seeds from this pomegranate, one by one!” and he began preparations for reducing the Moorish strongholds. But he was not to strike the first blow, for the old King of Granada, confident in the wealth of his provinces and the strength of his defences, and urged on by his fiery soldiery, led an army against an isolated frontier post of the Christians called Zahara. It was naturally so strong, being perched upon a craggy crest of a mountain, that its garrison neglected to keep watch, and, one dark and stormy night, was surprised and put to the sword. The wretched captives taken in the town below were driven like cattle to Granada; and thus in the year 1481 the gauntlet of war was thrown down by Muley Hassan, King of the Moors. King Ferdinand was willing enough to take it up; in truth, had the Moors not taken the initiative, war would have eventuated just the same, for the one darling project of the Christian sovereigns was the expulsion of the Arabs from the country. But yet again the Christian king was forestalled, though this time it was by one of his own cavaliers. The valiant Marquis of Cadiz, Roderigo Ponce de Leon, who owned vast estates in Andalusia, and could assemble a small army of his own retainers, resolved to avenge Zahara and strike a terrible blow at the Moors. Informed by his spies that the Moorish town and castle of Alhama, in the mountains of Granada, were but carelessly defended, he gathered together a small force of cavalry and foot soldiers, and, surprising the garrison and scaling the walls, took both castle and town by storm.
