The First Crusade (1096–1099) was the first of a number of crusades that attempted to recapture the Holy Land, called for by Pope Urban II at the Council of Clermont in 1095. Urban called for a military expedition to aid the Byzantine Empire, which had recently lost most of Anatolia to the Seljuq Turks. The resulting military expedition of primarily French-speaking Western European nobles, known as the Princes' Crusade, not only re-captured much of Anatolia but went on to conquer the Holy Land (the Levant), which had fallen to Islamic expansion as early as the 7th century, and culminated in July 1099 in the re-conquest of Jerusalem and the establishment of the Kingdom of Jerusalem.

The expedition was a response to the appeal for military aid by Byzantine Emperor Alexios I Komnenos. Urban's convocation of the Council of Clermont was specifically dedicated to this purpose, proposing siege warfare against the recently occupied cities of Nicaea and Antioch, even though Urban's speech at Clermont in the testimony of witnesses writing after 1100 was phrased to allude to the re-conquest of Jerusalem and the Holy Land as additional goals.

The successful Princes' Crusade was preceded by the People's Crusade, which was a popular movement instigated by Peter the Hermit in the spring of 1096. Mobs of peasants and laymen travelled to Anatolia where they came up against the Turks, on the way attacking populations of Jews in the Rhineland. They were decisively defeated at the Battle of Civetot in October.

The Princes' Crusade, by contrast, was a well-organized military campaign, starting out in late summer of 1096 and arriving at Constantinople between November 1096 and April 1097. The crusaders marched into Anatolia, capturing Nicaea in June 1097 and Antioch in June 1098. They arrived at Jerusalem in June 1099 and took the city by assault on 7 July 1099, massacring the defenders. A brief attempt by the Saracens to recapture Jerusalem was repulsed at the Battle of Ascalon.

During their conquests, the crusaders established the Crusader states of the Kingdom of Jerusalem, the County of Tripoli, the Principality of Antioch, and the County of Edessa. This was contrary to the wishes of the Eastern Rite Byzantines, who wanted the land that the Muslims took from them returned, rather than occupied by Latin Catholics. After the retaking of Jerusalem, most of the crusaders returned home. This left the crusader kingdoms vulnerable to Muslim reconquest during the Second and Third Crusades.

Historical context

The causes of the Crusades in general, and particularly of the First Crusade, is widely debated among historians. While the relative weight or importance of the various factors may be the subject of ongoing disputes, it is clear that the First Crusade came about from a combination of factors in both Europe and the Near East. Its origin is linked both with the political situation in Catholic Christendom, including the political and social situation in 11th-century Europe, the Gregorian Reform within the papacy,[3] as well as the military and religious confrontation of Christianity and Islam in the East.

Christianity had been adopted throughout the Roman Empire in Late Antiquity, but in the 7th to 8th centuries, the Umayyad Caliphate had conquered Syria, Egypt, and North Africa from the predominantly Christian Byzantine (Eastern Roman) Empire, and Hispania from the Visigothic Kingdom.[4] In North Africa, the Umayyad empire eventually collapsed and a number of smaller Muslim kingdoms emerged, such as the Aghlabids, who attacked Italy in the 9th century. Pisa, Genoa, and the Principality of Catalonia began to battle various Muslim kingdoms for control of the Mediterranean Basin, exemplified by the Mahdia campaign of 1087 and battles at Majorca and Sardinia.[5]

Between the years of 1096 and 1101, the Byzantine Greeks experienced the crusade as it arrived in Constantinople in three separate waves. In the early summer of 1096, the first large unruly group arrived on the outskirts of Constantinople. This wave was reported to be undisciplined and ill-equipped as an army. This first group is often called the Peasants' Crusade or the People's Crusade. It was led by Peter the Hermit and Walter Sans Avoir.

The second wave was also not under the command of the Emperor and was made up of a number of armies with their own commanders. Together, this group and the first wave numbered an estimated 60,000.[6][7]

The second wave was led by Hugh I, Count of Vermandois, the brother of King Philip I of France. Also among the second wave were Raymond IV, Count of Toulouse and the army of Provençals. "It was this second wave of crusaders which later passed through Asia Minor, captured Antioch in 1098 and finally took Jerusalem 15 July 1099."[8]

The third wave, composed of contingents from Lombardy, France, and Bavaria, arrived in Jerusalem in the early summer of 1101.[9]

Situation in Europe

At the western edge of Europe and of Islamic expansion, the Reconquista in the Iberian Peninsula was well underway by the 11th century. It was intermittently ideological, as evidenced by the Codex Vigilanus compiled in 881.[10][note 1] Increasingly in the 11th  century foreign knights, mostly from France, visited Iberia to assist the Christians in their efforts.[11][note 2] Shortly before the First Crusade, Pope Urban II had encouraged the Iberian Christians to reconquer Tarragona, using much of the same symbolism and rhetoric that was later used to preach the crusade to the people of Europe.[12]

The heart of Western Europe had been stabilized after the Christianization of the Saxon, Viking, and Hungarian peoples by the end of the 10th century. However, the breakdown of the Carolingian Empire gave rise to an entire class of warriors who now had little to do but fight among themselves.[13] The random violence of the knightly class was regularly condemned by the church, and in response, it established the Peace and Truce of God to prohibit fighting on certain days of the year. At the same time, the reform-minded papacy came into conflict with the Holy Roman Emperors, resulting in the Investiture Controversy. Popes such as Gregory VII justified the subsequent warfare against the Emperor's partisans in theological terms. It became acceptable for the Pope to utilize knights in the name of Christendom, not only against political enemies of the Papacy, but also against Al-Andalus, or, theoretically, against the Seljuq dynasty in the east.[14]

To the east of Europe lay the Byzantine Empire, composed of Christians who had long followed a separate Orthodox rite; the Eastern Orthodox and Roman Catholic churches had been in schism since 1054. Historians have argued that the desire to impose Roman church authority in the east may have been one of the goals of the crusade,[15] although Urban II, who launched the First Crusade, never refers to such a goal in his letters on crusading. The Seljuq Turks had taken over almost all of Anatolia after the Byzantine defeat at the Battle of Manzikert in 1071; however, their conquests were piecemeal and led by semi-independent warlords, rather than by the sultan. A dramatic collapse of the empire's position on the eve of the Council of Clermont brought Byzantium to the brink of disaster.[16] By the mid-1090s, the Byzantine Empire was largely confined to Balkan Europe and the northwestern fringe of Anatolia, and faced Norman enemies in the west as well as Turks in the east.[17] In response to the defeat at Manzikert and subsequent Byzantine losses in Anatolia in 1074, Pope Gregory VII had called for the miles Christi ("soldiers of Christ") to go to Byzantium's aid. This call was largely ignored and even opposed.[18] The reason for this was that while the defeat at Manzikert was shocking, it had limited significance and did not lead to major difficulties for the Byzantine empire, at least in the short term.[19]

Situation in the East

The Byzantine empire had lost control over most of Anatolia in the decade following the disastrous Battle of Manzikert.

Until the Crusaders' arrival, the Byzantines had continually fought the Seljuqs and other Turkish dynasties for control of Anatolia and Syria. The Seljuqs, who were orthodox Sunni Muslims, had formerly ruled the Great Seljuq Empire, but by the time of the First Crusade it had divided into several smaller states after the death of Malik-Shah I in 1092.

Malik-Shah was succeeded in the Anatolian Sultanate of Rum by Kilij Arslan I, and in Syria by his brother Tutush I, who died in 1095. Tutush's sons Fakhr al-Mulk Radwan and Duqaq inherited Aleppo and Damascus respectively, further dividing Syria amongst emirs antagonistic towards each other, as well as Kerbogha, the atabeg of Mosul.[20]

Egypt and much of Palestine were controlled by the Arab Shi'ite Fatimid Caliphate, which was significantly smaller since the arrival of the Seljuqs. Warfare between the Fatimids and Seljuqs caused great disruption for the local Christians and for western pilgrims. The Fatimids, under the nominal rule of caliph al-Musta'li but actually controlled by vizier al-Afdal Shahanshah, had lost Jerusalem to the Seljuqs in 1073 (although some older accounts say 1076);[21] they recaptured it in 1098 from the Artuqids, a smaller Turkish tribe associated with the Seljuqs, just before the arrival of the crusaders.[22]
