In the 7th cent., Jerusalem was taken by the caliph Umar. Pilgrimages (see pilgrim) were not cut off at first, but early in the 11th cent. the Fatimid caliph Hakim began to persecute the Christians and despoiled the Holy Sepulcher. Persecution abated after his death (1021), but relations remained strained and became more so when Jerusalem passed (1071) from the comparatively tolerant Egyptians to the Seljuk Turks, who in the same year defeated the Byzantine emperor Romanus IV at Manzikert.
Late in the 11th cent., Byzantine Emperor Alexius I, threatened by the Seljuk Turks, appealed to the West for aid. This was not the first appeal of the kind; while it may have helped to determine the time and the route of the First Crusade, 1095–99, its precise import is difficult to estimate. Modern historians have speculated that two internal problems also helped trigger the First Crusade: an attempt, begun by Pope Gregory VII, to reform the church, and the pressing need to strengthen the weakened Papacy itself. Direct impetus was given the crusade by the famous sermon of Pope Urban II at the Council of Clermont (now Clermont-Ferrand) in 1095. Exaggerating the anti-Christian acts of the Muslims, Urban exhorted Christendom to go to war for the Sepulcher, promising that the journey would count as full penance and that the homes of the absent ones would be protected by a truce. The battle cry of the Christians, he urged, should be Deus volt [God wills it]. From the crosses that were distributed at this meeting the Crusaders took their name. Bishop Ademar of Le Puy-en-Velay was designated as papal legate for the crusade, and Count Raymond IV of Toulouse was the first of the leaders of the expedition to take the cross.
Proclaimed by many wandering preachers, notably Peter the Hermit, the movement spread through Europe and even reached Scandinavia. It is estimated that between 60,000 and 100,000 heeded the call and took up the cause of the First Crusade. The chief factors that contributed to this enthusiastic response were the increase in the population and prosperity of Western Europe; the high point that religious devotion had reached; the prospect of territorial expansion and riches for the nobles, and of more freedom for the lower classes; the colonial projects of the Normans (directed against the Byzantine Empire as much as against the Muslim world); the desire, particularly of the Italian cities, to expand trade with the East; and a general awakening to the lure of travel and adventure.
The conflict between spiritual and material aims, apparent from the first, became increasingly serious. The organized host of the crusade was preceded in the spring of 1096 by several undisciplined hordes of French and German peasants. Walter Sans Avoir (Walter the Penniless) led a French group, which passed peacefully through Germany and Hungary but sacked the district of Belgrade. The Bulgarians retaliated, but Walter reached Constantinople by midsummer. He was joined there by the followers of Peter the Hermit, whose progress had been similar. A German group started off by robbing and massacring the Jews in the Rhenish cities and later so provoked the king of Hungary that he attacked and dispersed them.
The bands that had reached Constantinople were speedily transported by Alexius I to Asia Minor, where they were defeated by the Turks. The survivors either joined later bands or returned to Europe. Alexius began to take fright at the proportions the movement was assuming. When, late in 1096, the first of the princes, Hugh of Vermandois, a brother of Philip I of France, reached Constantinople, the emperor persuaded him to take an oath of fealty. Godfrey of Bouillon and his brothers Eustace and Baldwin (later Baldwin I of Jerusalem), Raymond IV of Toulouse, Bohemond I, Tancred, Robert of Normandy, and Robert II of Flanders arrived early in 1097. At Antioch all except Tancred and Raymond (who promised only to refrain from hostilities against the Byzantines) took the oath to Alexius, which bound them to accept Alexius as overlord of their conquests. Bohemond's subsequent breach of the oath was to cause endless wrangling.
The armies crossed to Asia Minor, took Nicaea (1097), defeated the Turks at Dorylaeum, and, after a seven-month siege, took Antioch (1098) and slaughtered nearly all of its inhabitants, including its Christians. The campaign was completed in July, 1099, by the taking of Jerusalem, where they massacred the city's Muslims and Jews. The election of Godfrey of Bouillon as defender of the Holy Sepulcher marked the beginning of the Latin Kingdom of Jerusalem (see Jerusalem, Latin Kingdom of). A Latin patriarch was elected. Other fiefs, theoretically dependent on Jerusalem, were created as the crusade's leaders moved to expand their domains. These were the counties of Edessa (Baldwin) and Tripoli (Raymond) and the principality of Antioch (Bohemond).
The First Crusade thus ended in victory. It was the only crusade that achieved more than ephemeral results. Until the ultimate fall (1291) of the Latin Kingdom, the brunt of the fighting in the Holy Land fell on the Latin princes and their followers and on the great military orders, the Knights Hospitalers and the Knights Templars, that arose out of the Crusades.
