The last of the Fatimite caliphs, El-Adid, in 555 a.h., was raised to the throne by Tataë, but his power was merely the shadow of sovereignty. Tataë’s tyranny, however, became so odious that the caliph had him assassinated a year after his accession, but he concealed the fact that he had instigated the murder. The caliph appointed Tataë’s son, El-Adil, as vizier in his stead. The governorship of Upper Egypt was at this time in the hands of the celebrated Shawir, whom El-Adil dispossessed, but in a test of battle, El-Adil was defeated and put to death. In his turn, Shawir yielded to the more powerful Ed-Durghan, and fled to Damascus. There he enlisted the aid of the Atabeg Sultan Nur ed-Din, who sent his army against Ed-Durghan, with the result that Shawir was reinstated in power in Egypt. He thereupon threw off his promised allegiance to Nur ed-Din, whose general, Shirkuh (who had led the Damascenes to Egypt), took up a strategic position. Shawir appealed for aid to the Crusaders, and with the help of Amaury, King of Jerusalem, Shawir besieged his friend Shirkuh. Nur ed-Din was successfully attacking the Crusaders elsewhere, and in the end a peace was negotiated, and the Damascenes left Egypt.
Two years later, Nur ed-Din formulated a plan to punish the rebellious Shawir. Persecuted by Shirkuh, Nur ed-Din sent him with his army into Egypt. The Franks now joined with Shawir to defend the country, hoping thereby to baffle the schemes of Nur ed-Din. The Christian army was amazed at all the splendour of the caliph’s palace at Cairo. Shawir retreated to entice the invaders on, who, advancing beyond their base, were soon reduced to straits. Shirkuh then tried to come to terms with Shawir against the Christians as a common foe, but without success. He next thought of retreating, without fighting, with all his Egyptian plunder. Persuaded at length to fight, he defeated the Franks and finally came to terms with Shawir, whereby the Franco-Egyptian alliance came to an end, and he then left Egypt on receiving an indemnity, Shawir still remaining its ruler.
The peace, however, did not last long, and Nur ed-Din sent Shirkuh again with many Frankish free-lancers against the ill-fated country. On the approach of the army towards Cairo, the vizier set fire to the ancient city of Fostât, to prevent it from falling into the hands of the invaders, and it burned continually for fifty days. El-Adid now sought aid of Nur ed-Din, who, actuated by zeal against the Franks, and by desire of conquest, once more despatched Shirkuh. In the meantime negotiations had been opened with Amaury to raise the siege of Cairo on payment of an enormous sum of money. But, before these conditions had been fulfilled, the approach of the Syrian army induced Amaury to retreat in haste. Shirkuh and Saladin entered the capital in great state, and were received with honour by the caliph, and with obsequiousness by Shawir, who was contriving a plot which was fortunately discovered, and for which he paid with his life. Shirkuh was then appointed vizier by El-Adid, but, dying very shortly, he was succeeded in that dignity by his nephew Saladin (A.D. 1169).
Saladin inaugurated his reign with a series of brilliant successes. Egypt once again took an important place among the nations, and by the wars of Saladin it became the nucleus of a great empire. Military glory was never the sole aim of Saladin and his successors. They continued to extend to letters and the arts their willing patronage, and the beneficial effects of this were felt upon the civilisation of the country. Though ruler of Egypt, Saladin gained his greatest renown by his campaigns against the Crusaders in Syria. The inability of Nur ed-Din’s son, El-Malik es-Salih Ismail, to govern the Syrian dominions became an excuse for Saladin’s occupation of Syria as guardian of the young prince, and, once having assumed this function, he remained in fact the master of Syria. He continued to consolidate his power in these parts until the Crusaders, under Philip, Count of Flanders, laid siege to Antioch. Saladin now went out to meet them with the Egyptian army, and fought the fierce battle of Ascalon, which proved to be disastrous to himself, his army being totally defeated and his life endangered. After this, however, he was fortunate enough to gain certain minor advantages, and continued to hold his own until a famine broke out in Palestine which compelled him to come to terms with the Crusaders, and two years later a truce was concluded with the King of Jerusalem, and Saladin returned to Egypt.
In the year 576 a.h., he again entered Syria and made war on Kilidj-Arslan, the Seljukide Sultan of Anatolia, and on Leon, King of Armenia, both of whom he forced to come to terms. Soon after his return, Saladin again left Egypt to prosecute a war with the Crusaders, since it was plain that neither side was desirous of remaining at peace. Through an incident which had just occurred, the wrath of the Crusaders had been kindled. A vessel bearing fifteen hundred pilgrims had been wrecked near Damietta, and its passengers captured. When the King of Jerusalem remonstrated, Saladin replied by complaining of the constant inroads made by Renaud de Châtillon. This restless warrior undertook an expedition against Eyleh, and for this purpose constructed boats at Kerak and conveyed them on camels to the sea. But this flotilla was repulsed, and the siege was raised by a fleet sent thither by El-Adil, the brother of Saladin, and his viceroy. A second expedition against Eyleh was still more unfortunate to the Franks, who were defeated and taken prisoners. On this occasion the captives were slain in the valley of Mina. Saladin then threatened Kerak, encamped at Tiberias, and ravaged the territory of the Franks. He next made a futile attempt to take Beirut. He was more successful in a campaign against Mesopotamia, which he reduced to submission, with the exception of Mosul. While absent here, the Crusaders did little except undertake several forays, and Saladin at length returned towards Palestine, winning many victories and conquering Aleppo on the way. He next ravaged Samaria, and at last received the fealty of the lord of Mosul, though he did not succeed in actually conquering the city.
In the year 1186 war broke out again between Saladin and the Christian hosts. The sultan had respected a truce which he had made with Baldwin the Leper, King of Jerusalem, but the restless Renaud, who had previously attacked Eyleh, had broken through its stipulations. His plunder of a rich caravan enraged Saladin, who forthwith sent out orders to all his vassals and lieutenants to prepare for a Holy War. In the year 1187 he marched from Damascus to Kerak, where he laid close siege to Renaud. At the same time a large body of cavalry was sent on towards Nazareth under his son El-Afdhal. They were met by 730 Knights Hospitallers and Templars, aided by a few hundred foot-soldiers. Inspired by the heroic Jacques de Maillé, marshal of the Temple, they defied the large Saracen army. In the conflict which ensued, the Crusaders immortalised themselves by fighting until only three of their number were left alive, who, after the conflict was over, managed to escape.
Soon after this, Saladin himself approached with a great army of eighty thousand men, and the Christians with all their forces hastened to meet him upon the shores of Lake Tiberias. The result of this battle proved to be the most disastrous defeat which the Christians had yet suffered. They were weakened by thirst, and on the second day of the conflict a part of their troops fled. But the knights nevertheless continued to make a heroic defence until they were overwhelmed by numbers and forced to flee to the hills of Hittûn. A great number of Crusaders fell in this conflict, and Guy de Lusignan, King of Jerusalem, and his brother, Renaud de Châtillon, were among the prisoners of war. The number of those taken was very great, and Saladin left an indelible stain upon a reign otherwise renowned for mercy and humanity by allowing the prisoners to be massacred. Tiberias, Acre, Nabulus, Jericho, Ramleh, Cæsarea, Arsûr, Jaffa, Beirut, and many other places now fell into the hands of the conqueror.
