The character of Abd-al-Mumen presents an epitome of the homely virtues and ferocious vices of the Desert. In the attainment of his ends he was seldom swayed by considerations of pity, honor, or benevolence. He never shrank from indiscriminate butchery in the heat of battle. He seldom hesitated to pardon a defeated and submissive foe. In the dispensation of justice the culprit promptly underwent the extreme penalty of violated law. The attention of the founder of a stupendous empire was not entirely engrossed by schemes of war and conquest. He established schools and colleges in the larger cities of his dominions, fostered literature, encouraged art. The most talented and accomplished teachers in the entire realm of Islam were attracted to his court, where, honored with the friendship and enriched by the liberality of their royal patron, their efforts were directed to the education of youth. Three thousand of the latter, selected from the most distinguished families, were assembled in a university at the capital, where they not only profited by the instruction of learned professors, but were daily exercised in the military evolutions essential to a competent knowledge of the art of war—the manœuvring, the encampment, and the discipline of armies. Under the care of such a monarch the city of Morocco became a metropolis worthy of an empire which comprehended an hundred distinct tribes and nations, and whose opposite boundaries were separated by a four months’ journey. The royal residence and its gardens enclosed a vast area beautified by every resource of art and luxury. The inventive genius of skilful foreign artisans had provided both palace and mosque with many appliances of wonderful ingenuity,—doors which opened and closed apparently without human agency; pulpits and tribunes which, acting automatically, moved to and fro impelled by hidden mechanism; fountains whose jets, mysteriously controlled by valves and springs, were the perpetual delight and wonder of the people.

Under his administration hundreds of vessels were constructed; the navy-yards were enlarged and increased in number, and powerful fleets bearing the white standard of the Almohades maintained the dignity of the Sultan of Africa and Spain in every quarter of the Mediterranean.

The long reign of Abd-al-Mumen, who governed Spain entirely through his viceroys, was not less injurious to the interests of that country than the domination of the Almoravides had been. The plague of civil war, the menace of Christian conquest, the evils of revolution and anarchy, the ferocity of the remorseless conqueror, with whom resistance was an offence only to be expiated by death or slavery, were conditions fatal to agricultural and commercial prosperity. Moorish Spain, once the proud mistress of the Occident, the seat of learning and the arts, now the sport of fortune and the prey of savage hordes nurtured amidst the African deserts, was, with the passage of each decade, rapidly descending in the scale of civilization. Her political influence and the prestige of her name had disappeared. The wealth accumulated under the beneficent rule of the Ommeyade dynasty had either been dissipated in luxury or been borne away by barbarian invaders. The time was almost at hand when a religious tyranny, more grievous in its burdens, more cruel in the inexorable severity of its decrees, than the worst examples of African despotism, was to be imposed on the descendants of a people which had made the Western Khalifate the seat of the most opulent, the most intellectual, the most powerful of nations.

Yusuf, the new Sultan of the Almohades, distrusting the loyalty of his subjects, and apprehensive of a disputed succession, had no sooner ascended the throne than he disbanded the great army collected by his father for the subjection of the Peninsula. A well-balanced and discriminating mind, an excellent education acquired under the direction of the most learned doctors of the age, unusual proficiency in the martial exercises practised with such assiduity by the Mauritanian youth, considerable experience in the arts of policy and in the conduct of campaigns, admirably fitted Yusuf for the cares of government. The summary measures adopted by his father to maintain public security, and his own well-established reputation for ability and resolution, preserved his accession from the dangers of revolt. A few insignificant demonstrations by the restless tribes of the Atlas, which were speedily and mercilessly repressed, disturbed the first few months of his reign. But no pretender rose to dispute his claims to sovereignty; no prophet ventured to arouse the credulous and fanatical swarms of the Desert; no concerted movement of discontented chieftains threatened the permanence of a monarchy which had been founded on revolution, and whose history had been marked by incessant turmoil and sedition. Satisfied with the peaceful condition of his African possessions, Yusuf, having sent to Spain twenty thousand of his choicest troops, after a short delay followed them, and, assuming the supreme command, established his residence at Seville. The discord existing between the petty rulers of the Moslem states, whose enmity was the more decided in proportion to their incapacity to indulge it, operated in the most signal manner to the advantage of his cause. Ibn-Saad, lord of Eastern Spain, whose kingdom included the cities of Murcia, Valencia, Alicante, Xativa, Denia, Lorca, many flourishing villages, and the most fertile portion of the Peninsula, was killed in an expedition to Minorca, and his sons, unable to defend their rich inheritance against both the Aragonese and the Almohades at once, entered into negotiations with Yusuf for the exchange of their territories for others less valuable, perhaps, but more secure, on the shores of Northern Africa. The bargain was soon concluded. The Murcian princes, eager to dispose of what they must otherwise inevitably lose, embarked for their new dominions; the daughter of Ibn-Saad, a pledge of the contract, became the wife of Yusuf, and the most valuable district in Spain—when the productiveness of the soil, the wealth and commercial advantages of the cities, and the density and industrious character of the population are considered—passed, without the hazards of a campaign or the loss of a single drop of blood, under the control of the Sultan of the Almohades.

It was not, however, by the peaceable arts of diplomacy alone that additions were made to the empire of Yusuf. In the west, Badajoz, repeatedly captured and retaken by Christian and Moslem, was occupied by his troops. At the head of a column of several thousand cavalry he ravaged the valley of the Tagus as far as the suburbs of Toledo. The border stronghold of Alcantara, long vaunted as impregnable, submitted to his arms. Nor was it on account of his military exploits that the name of Yusuf has been transmitted to the admiration of posterity. Although he passed but a year in the most enchanting of Andalusian cities, the evidences of his presence are to-day the principal, almost the sole, attractions of that beautiful capital. The memory of his genius and munificence have been perpetuated by the erection of quays, palaces, towers, whose stupendous dimensions are now the wonder of the modern engineer, and of mosques whose minarets were once incomparable models of architectural symmetry and elegance. He repaired and enlarged the Roman aqueduct, which still conducts from the springs of Alcalá the purest water for the use of Seville. He spanned the Guadalquivir with a bridge of boats, the counterpart and predecessor of the one which until within a century united the opposite banks of that broad and rapid stream. Its inundations, which had previously damaged property and imperilled life, were partially controlled by the construction of gigantic walls, which arrested the destructive torrent and turned it again into its proper channel. These structures served as quays, which, approached from the river-side by broad and easy stairways, greatly facilitated the unloading and shipment of merchandise. Near at hand were warehouses and magazines designed and erected by Yusuf, and whose convenience and capacity were not surpassed by those of any Mediterranean seaport. The defences of the city also claimed the attention of this wise and indefatigable monarch, whose care and vigilance no detail, however insignificant, seemed to escape. The ancient walls were repaired and new ones constructed. Numerous towers were added to command the river, among them the peculiar one now known as the Tower of Gold, where was once kept the royal treasure. In the heart of the city, and on the site of an ancient Christian church, a great mosque was founded. The plan was a rectangle of four hundred and fourteen by two hundred and seventy feet, and, although it could not in justice be considered a rival of that noble edifice, it was in many respects not far inferior to the peerless Djalma of Cordova. Its walls were fringed with Persian battlements and painted with many colors. Its arcades looked upon a court supplied with ever-murmuring fountains and fragrant with the odor of orange blossoms. Its hundreds of marble columns suggested the spoliation of many a Pagan temple. The ceiling was formed by domes of wood and stucco, whose geometrical patterns disclosed the correctness of taste and inexhaustible fertility of fancy characteristic of the labors of the Arab artist and gilder. Its mosaic pavements, its alabaster lattices, its curious arabesques presented finished types of Moorish decorative splendor nowhere more conspicuous than in his places of religious worship. At one corner of the building rose a minaret of moderate height but elaborate ornamentation, and diagonally opposite were laid the foundations of that famous tower now known as the Giralda, which, completed during the reign of the successor of Yusuf, still remains the finest specimen of Moslem architecture of its class in the world.

It was not alone in the improvement of his Spanish capital that the time and energy of the Almohade Sultan were expended. The military and naval advantages of Gibraltar had been early appreciated by the sovereigns of Africa. Its fortifications were now greatly extended and strengthened by the provident foresight of Yusuf, who recognized in its peculiar and impregnable situation the security of the Strait and the key of the Peninsula.

Summoned to Africa by the ravages of a pestilence which decimated the population of his kingdom, ignorant of medical knowledge, and abandoned to fatalism and the ministrations of charlatans, Yusuf was compelled to suspend the public works which had already produced such beneficial results amidst the decaying commerce and diminishing resources of Andalusia. The absence of the monarch became, as usual, the pretext for anarchy. With his departure the quarrels of ambitious governors of provinces and the harassing forays of the Christians were renewed. For the long period of eight years this condition of incessant and ruinous hostility continued. Then Yusuf resolved to accomplish the design matured by his father, but whose execution had been prevented by death. The Holy War was proclaimed. The forces of Africa were assembled at Ceuta, and Spain was invaded by one of the largest armies that had ever been marshalled on her soil. It is with interest that we read of the orderly but undisciplined progress of this great array. The tribes marched separately under their several sheiks. Each tribe carried its distinctive standard—the ensign of that which constituted the vanguard, the post of honor, was of blue and white silk spangled with golden crescents. In the centre of the host rode the monarch, surrounded by his negro guard, in whose equipment had been lavished all the wealth of barbaric magnificence. Before him was carried, as a talisman to insure success, the great Koran of Othman, which, having escaped the perils of many revolutions, had been sent to Morocco by the Almohades after their capture of Cordova. It was escorted by a company of a hundred Berber nobles, mounted upon superb Arabian horses whose velvet housings were embroidered with gold. This guard of honor carried lances inlaid with ivory and silver, from which fluttered pennons of many-colored silk. The casket in which was deposited the most priceless relic of Islam was the same which had been adorned by the emulous devotion and prodigality of many generations of Moslem princes. Its material of ebony and sandal-wood was entirely concealed by the multitude of jewels with which it was encrusted. The greater part of these were emeralds and rubies, and were kept in place by heavy settings of gold. They were arranged in arabesques, and in the centre of each design sparkled a magnificent ruby cut in horseshoe form. The casket was lined with green silk and cloth-of-gold, and a covering of the same material sowed with pearls and other precious stones concealed the treasure from the eyes of the multitude. Its weight, which was far from inconsiderable, was supported by a stately camel, whose burden was sheltered by a canopy on which were emblazoned in golden letters appropriate legends from the Koran. In the rear of the Sultan came the princes of the blood, the royal tributaries, and the grand officials of the empire. Seventy thousand infantry and thirty thousand cavalry composed the available force of the invaders, whose ranks were further augmented by at least a hundred thousand slaves and dependents. The army moved in four divisions, a day’s journey apart; at each halting-place provisions and forage had been collected, and the perfection of these arrangements, as well as the order maintained on the march, attested the military skill and executive ability of the Moslem general.

At Seville, designated as the rendezvous of the Spanish contingent, Yusuf was joined by several thousand Berber troops, who had served through many campaigns in the Peninsula. He then crossed the frontier of Portugal and besieged Santarem. This city, situated about fifty miles from Lisbon, was regarded as the bulwark of that capital. It was on the point of being taken, when Yusuf was surprised by an unexpected sally of the besiegers and mortally wounded. The Moslems, goaded to madness by this misfortune, drove back the attacking party, entered the gates with the fugitives, and ten thousand persons, massacred amidst the horrors of the unequal conflict, expiated the temporary and fatal success of a handful of their number. The death of the Sultan, which, to avoid political complications and civil war, was kept a secret, and did not become publicly known until his successor, Abu-Yakub-Ibn-Yusuf,—the ablest of his many sons, and who assumed the title of Al-Mansur-Billah,—a few weeks afterwards ascended the throne. The traits of Yusuf were those of a liberal, a just, a devout, a magnanimous ruler. He reduced taxation. He increased the imperial revenues. His inexorable severity was the terror of malefactors. Before his tribunals no suitor could complain of judicial oppression or venality. Under his administration, as under that of his father, the clergy were restricted to the performance of their religious duties, and were not permitted to usurp the functions or to absorb the revenues of the civil power. The cities were patrolled by a well-appointed and vigilant police, and law-abiding citizens were assured of protection. The banditti disappeared from the highways before the untiring pursuit of the authorities, who crucified every brigand as soon as he was captured. Never since the most flourishing days of the Ommeyade empire had the people of Moorish Spain enjoyed such security.

According to Moslem custom, Yakub signalized his ascent to the throne by acts of public charity and benevolence. He caused to be distributed as alms the sum of a hundred thousand pieces of gold. He increased the compensation of such officials as had honestly and faithfully administered the public service. The taxes of the poor were remitted, the tributes of the wealthy were reduced. The prisons were cleared of all offenders except such as were accused of capital crimes. Upon every magistrate was sedulously impressed the necessity for the strict yet merciful enforcement of the laws. The army was placed under better discipline, the pay of the soldiers was increased, and the sanitary conditions of the barracks and the camp improved. In both Spain and Africa new fortresses were erected at points peculiarly exposed to the incursions of an enemy. Great sums were expended in the improvement and the construction of highways, and the bridges were placed in perfect repair, that no obstacle might exist to the rapid movement of couriers or to easy military communication between the seat of government and the frontiers of the empire. At regular intervals along these thoroughfares, wells were dug and stations established for the shelter of travellers and the convenience of troops. The obligations of religion and the demands of knowledge were not neglected by this devout and generous ruler. Mosques, richly adorned, were built in every considerable town and city, and attached to them were institutions of learning, where gratuitous instruction was furnished to the poor but aspiring student. The sufferings of the afflicted were relieved by the establishment of hospitals, presided over by physicians and surgeons thoroughly versed in the medical science of the age. To such a degree had the traditions and example of the Western Khalifate awakened the noble emulation of the greatest prince who ever traced his origin to an African ancestor.

The commencement of the reign of Yakub, like those of his predecessors, was distracted by war and sedition. The remains of the Almoravide faction, established in the Balearic Isles, instigated by delusive representations the tribes of the Desert and the malcontents of the Peninsula to insurrection. Their efforts were, however, incapable of seriously endangering the power of Yakub. The leaders were arrested, and the adoption of the most energetic measures soon restored the public tranquillity. The repentant Berbers implored with success the royal clemency; and two of the brothers of the Sultan, involved in the common guilt, were sacrificed to the stern demands of justice and fraternal indignation.
