Overview

The First Crusade (1095–1099), called for by Pope Urban II, was the first of a number of crusades intended to recapture the Holy Lands. It started as a widespread pilgrimage in western Christendom and ended as a military expedition by Roman Catholic Europe to regain the Holy Lands taken in the Muslim conquests of the Mediterranean (632–661), ultimately resulting in the recapture of Jerusalem in 1099.

It was launched on November 27, 1095, by Pope Urban II with the primary goal of responding to an appeal from Byzantine Emperor Alexios I Komnenos, who requested that western volunteers come to his aid and help to repel the invading Seljuq Turks from Anatolia (modern-day Turkey). An additional goal soon became the principal objective—the Christian reconquest of the sacred city of Jerusalem and the Holy Land and the freeing of the Eastern Christians from Muslim rule.

During the crusade, knights, peasants, and serfs from many regions of Western Europe travelled over land and by sea, first to Constantinople and then on toward Jerusalem. The Crusaders arrived at Jerusalem, launched an assault on the city, and captured it in July 1099, massacring many of the city’s Muslim and Jewish inhabitants. They also established the crusader states of the Kingdom of Jerusalem, the County of Tripoli, the Principality of Antioch, and the County of Edessa.

People’s Crusade

Pope Urban II planned the departure of the crusade for August 15, 1096; before this, a number of unexpected bands of peasants and low-ranking knights organized and set off for Jerusalem on their own, on an expedition known as the People’s Crusade, led by a monk named Peter the Hermit. The peasant population had been afflicted by drought, famine, and disease for many years before 1096, and some of them seem to have envisioned the crusade as an escape from these hardships. Spurring them on had been a number of meteorological occurrences beginning in 1095 that seemed to be a divine blessing for the movement—a meteor shower, an aurorae, a lunar eclipse, and a comet, among other events. An outbreak of ergotism had also occurred just before the Council of Clermont. Millenarianism, the belief that the end of the world was imminent, widespread in the early 11th century, experienced a resurgence in popularity. The response was beyond expectations; while Urban might have expected a few thousand knights, he ended up with a migration numbering up to 40,000 Crusaders of mostly unskilled fighters, including women and children.

Lacking military discipline in what likely seemed a strange land (Eastern Europe), Peter’s fledgling army quickly found itself in trouble despite the fact that they were still in Christian territory. This unruly mob began to attack and pillage outside Constantinople in search of supplies and food, prompting Alexios to hurriedly ferry the gathering across the Bosporus one week later. After crossing into Asia Minor, the crusaders split up and began to plunder the countryside, wandering into Seljuq territory around Nicaea, where they were massacred by an overwhelming group of Turks.

The First Crusade

The four main Crusader armies left Europe around the appointed time in August 1096. They took different paths to Constantinople and gathered outside the city walls between November 1096 and April 1097; Hugh of Vermandois arrived first, followed by Godfrey, Raymond, and Bohemond. This time, Emperor Alexios was more prepared for the Crusaders; there were fewer incidents of violence along the way.

The Crusaders may have expected Alexios to become their leader, but he had no interest in joining them, and was mainly concerned with transporting them into Asia Minor as quickly as possible. In return for food and supplies, Alexios requested that the leaders to swear fealty to him and promise to return to the Byzantine Empire any land recovered from the Turks. Before ensuring that the various armies were shuttled across the Bosporus, Alexios advised the leaders on how best to deal with the Seljuq armies they would soon encounter.

Siege of Nicaea and March to Jerusalem

The Crusader armies crossed over into Asia Minor during the first half of 1097, where they were joined by Peter the Hermit and the remainder of his little army. Alexios also sent two of his own generals, Manuel Boutoumites and Tatikios, to assist the Crusaders. The first object of their campaign was Nicaea, previously a city under Byzantine rule, but which had become the capital of the Seljuq Sultanate of Rum under Kilij Arslan I. Arslan was away campaigning against the Danishmends in central Anatolia at the time, and had left behind his treasury and his family, underestimating the strength of these new Crusaders.

Subsequently, upon the Crusaders’ arrival, the city was subjected to a lengthy siege, and when Arslan had word of it he rushed back to Nicaea and attacked the Crusader army on May 16. He was driven back by the unexpectedly large Crusader force, with heavy losses suffered on both sides in the ensuing battle. The siege continued, but the Crusaders had little success as they found they could not blockade Lake Iznik, which the city was situated on, and from which it could be provisioned. To break the city, Alexios had the Crusaders’ ships rolled over land on logs, and at the sight of them the Turkish garrison finally surrendered, 18 June 18. The city was handed over to the Byzantine troops.

At the end of June, the Crusaders marched on through Anatolia. They were accompanied by some Byzantine troops under Tatikios, and still harbored the hope that Alexios would send a full Byzantine army after them. After a battle with Kilij Arslan, the Crusaders marched through Anatolia unopposed, but the journey was unpleasant, as Arslan had burned and destroyed everything he left behind in his army’s flight. It was the middle of summer, and the Crusaders had very little food and water; many men and horses died. Fellow Christians sometimes gave them gifts of food and money, but more often than not the Crusaders simply looted and pillaged whenever the opportunity presented itself.

Proceeding down the Mediterranean coast, the crusaders encountered little resistance, as local rulers preferred to make peace with them and furnish them with supplies rather than fight.

Capture of Jerusalem

On June 7, the Crusaders reached Jerusalem, which had been recaptured from the Seljuqs by the Fatimids only the year before. Many Crusaders wept upon seeing the city they had journeyed so long to reach. The arrival at Jerusalem revealed an arid countryside, lacking in water or food supplies. Here there was no prospect of relief, even as they feared an imminent attack by the local Fatimid rulers. The Crusaders resolved to take the city by assault. They might have been left with little choice, as it has been estimated that only about 12,000 men, including 1,500 cavalry, remained by the time the army reached Jerusalem.

After the failure of the initial assault, a meeting between the various leaders was organized in which it was agreed upon that a more concerted attack would be required in the future. On June 17, a party of Genoese mariners under Guglielmo Embriaco arrived at Jaffa and provided the Crusaders with skilled engineers, and perhaps more critically, supplies of timber (cannibalized from the ships) with which to build siege engines. The Crusaders’ morale was raised when a priest, Peter Desiderius, claimed to have had a divine vision of Bishop Adhemar instructing them to fast and then march in a barefoot procession around the city walls, after which the city would fall, following the Biblical story of Joshua at the siege of Jericho.

The final assault on Jerusalem began on July 13; Raymond’s troops attacked the south gate while the other contingents attacked the northern wall. Initially the Provençals at the southern gate made little headway, but the contingents at the northern wall fared better, with a slow but steady attrition of the defense. On July 15, a final push was launched at both ends of the city, and eventually the inner rampart of the northern wall was captured. In the ensuing panic, the defenders abandoned the walls of the city at both ends, allowing the Crusaders to finally enter.

The massacre that followed the capture of Jerusalem has attained particular notoriety, as a “juxtaposition of extreme violence and anguished faith.” The eyewitness accounts from the Crusaders themselves leave little doubt that there was a great slaughter in the aftermath of the siege. Nevertheless, some historians propose that the scale of the massacre was exaggerated in later medieval sources. The slaughter lasted a day; Muslims were indiscriminately killed, and Jews who had taken refuge in their synagogue died when it was burnt down by the Crusaders. The following day, Tancred’s prisoners in the mosque were slaughtered. Still, it is clear that some Muslims and Jews of the city survived the massacre, either escaping or being taken prisoner to be ransomed. The Eastern Christian population of the city had been expelled before the siege by the governor, and thus escaped the massacre.

On July 22, a council was held in the Church of the Holy Sepulchre to establish a king for the newly created Kingdom of Jerusalem. Raymond IV of Toulouse and Godfrey of Bouillon were recognized as the leaders of the crusade and the siege of Jerusalem. Raymond was the wealthier and more powerful of the two, but at first he refused to become king, perhaps attempting to show his piety and probably hoping that the other nobles would insist upon his election anyway. The more popular Godfrey did not hesitate like Raymond, and accepted a position as secular leader.

Having captured Jerusalem and the Church of the Holy Sepulchre, the Crusaders had fulfilled their vow.
