The first Fatimite caliph, though without experience, was so vigorous a ruler that he could dispense with the dangerous support of his discoverer. He held the throne for a quarter of a century and established his authority, more or less continuously, over the Arab and Berber tribes and settled cities from the frontier of Egypt to the province of Fez (Fas) in Morocco, received the allegiance of the Mahometan governor of Sicily, and twice despatched expeditions into Egypt, which he would probably have permanently conquered if he had not been hampered by perpetual insurrections in Barbary. Distant governors, and often whole tribes of Berbers, were constantly in revolt, and the disastrous famine of 928-929, coupled with the Asiatic plague which his troops had brought back with them from Egypt, led to general disturbances and insurrections which fully occupied the later years of his reign. The western provinces, from Tahart and Nakur to Fez and beyond, frequently threw off all show of allegiance. His authority was founded more on fear than on religious enthusiasm, though zeal for the Alide cause had its share in his original success. The new "Eastern doctrines," as they were called, were enforced at the sword's point, and frightful examples were made of those who ventured to tread in the old paths. Nor were the freethinkers of the large towns, who shared the missionary's esoteric principles, encouraged; for outwardly, at least, the Mahdi was strictly a Moslem. When people at Kayrawan began to put in practice the missionary's advanced theories, to scoff at all the rules of Islam, to indulge in free love, pig's flesh, and wine, they were sternly brought to order. The mysterious powers expected of a mahdi were sedulously rumored among the credulous Berbers, though no miracles were actually exhibited; and the obedience of the conquered provinces was secured by horrible outrages and atrocities, of which the terrified people dared not provoke a repetition at the hands of the Mahdi's savage generals.
His eldest son Abul-Kasim, who had twice led expeditions into Egypt, succeeded to the caliphate with the title of El-Kaim, 934-946. He began his reign with warlike vigor. He sent out a fleet in 934 or 935, which harried the southern coast of France, blockaded and took Genoa, and coasted along Calabria, massacring and plundering, burning the shipping, and carrying off slaves wherever it touched. At the same time he despatched a third army against Egypt; but the firm hand of the Ikshid now held the government, and his brother, Obeid-Allah, with fifteen thousand horse, drove the enemy out of Alexandria and gave them a crushing defeat on their way home. But for the greater part of his reign El-Kaim was on the defensive, fighting for existence against the usurpation of one Abu-Yezid, who repudiated Shiism, cursed the Mahdi and his successor, stirred up most of Morocco and Barbary against El-Kaim, drove him out of his capital, and went near to putting an end to the Fatimite caliphate.
It was only after seven years of uninterrupted civil war that this formidable insurrection died out, under the firm but politic management of the third caliph, El-Mansur (946-953), a brave man who knew both when to strike and when to be generous. Abu-Yezid was at last run to earth, and his body was skinned and stuffed with straw, and exposed in a cage with a couple of ludicrous apes as a warning to the disaffected.
The Fatimites so far wear a brutal and barbarous character. They do not seem to have encouraged literature or learning; but this is partly explained by the fact that culture belonged chiefly to the orthodox caliphate; and its learned men could have no dealings with the heretical pretender. The city of Kayrawan, which dates from the Arab conquest in the eighth century, preserves the remains of some noble buildings, but of their other capitals or royal residences no traces of art or architecture remain to bear witness to the taste of their founders. Each began to decay as soon as its successor was built.
With the fourth caliph, however, El-Moizz, the conqueror of Egypt, 953-975, the Fatimites entered upon a new phase.
El-Moizz was a man of politic temper, a born statesman, able to grasp the conditions of success and to take advantage of every point in his favor. He was also highly educated, and not only wrote Arabic poetry and delighted in its literature, but studied Greek, mastered Berber and Sudani dialects, and is even said to have taught himself Slavonic in order to converse with his slaves from Eastern Europe. His eloquence was such as to move his audience to tears. To prudent statesmanship he added a large generosity, and his love of justice was among his noblest qualities. So far as outward acts could show, he was a strict Moslem of the Shiah sect, and the statement of his adversaries that he was really an atheist seems to rest merely upon the belief that all the Fatimites adopted the esoteric doctrines of the Ismailian missionaries.
When he ascended the throne in April, 953, he had already a policy, and he lost no time in carrying it into execution. He first made a progress through his dominions, visiting each town, investigating its needs, and providing for its peace and prosperity. He bearded the rebels in their mountain fastnesses, till they laid down their arms and fell at his feet. He conciliated the chiefs and governors with presents and appointments, and was rewarded by their loyalty.
At the head of his ministers he set Gawhar "the Roman," a slave from the Eastern Empire, who had risen to the post of secretary to the late Caliph, and was now by his son promoted to the rank of wazir commander of the forces. He was sent in 958 to bring the ever-refractory Maghreb (Morocco) to allegiance. The expedition was entirely successful, Sigilmasa and Fez were taken, and Gawhar reached the shore of the Atlantic.
Jars of live fish and sea-weed reached the capital, and proved to the Caliph that his empire touched the ocean, the "limitless limit" of the world. All the African littoral, from the Atlantic to the frontier of Egypt—with the single exception of Spanish Ceuta—now peaceably admitted the sway of the Fatimite Caliph.
The result was due partly to the exhaustion caused by the long struggle during the preceding reigns, partly to the politic concessions and personal influence of the able young ruler. He was liberal and conciliatory toward different provinces, but to the Arabs of the capital he was severe. Kayrawan teemed with disaffected folk, sheiks, and theologians bitterly hostile to the heretical "orientalism" of the Fatimites, and always ready to excite a tumult. Moizz was resolved to give them no chance, and one of his repressive measures was the curfew. At sunset a trumpet sounded, and anyone found abroad after that was liable to lose not only his way, but his head. So long as they were quiet, however, he used the people justly, and sought to impress them in his favor. In a singular interview, recorded by Makrisi, he exhibited himself to a deputation of sheiks, dressed in the utmost simplicity, and seated before his writing materials in a plain room, surrounded by books. He wished to disabuse them of the idea that he led in private a life of luxury and self-indulgence.
