The Crusades: the History of Christianity’s Wars for the Holy Land

Of the many campaigns during the Middle Ages, few are as remarkable or seemingly impossible to win at the start as the First Crusade (1095-99), and the true crowning achievement of that crusade, which resulted in two centuries of Western European Christian states in the Middle East and the permanent firing of the European imagination, was the conquest of Jerusalem on July 15, 1099 after three weeks of siege. That victorious siege came four years after the call for a crusade first went out, and had the Crusaders not taken Jerusalem, the First Crusade would not likely have been followed by any more and the campaign might have been no more than an historical footnote of what could have been.As it turned out, the siege of Jerusalem and the crusade as a whole says much about the first major clash of Western and Eastern military tactics after the fall of the Roman Empire, as well as the power of faith and even fanaticism to motivate people beyond ordinary human endurance. For better and worse, the siege and fall of Jerusalem to the Crusaders has become a fundamental piece in the current view of the West in that part of the world.Though it went largely unremarked in the Islamic world at the time, the First Crusade has since become a contentious symbol of European imperialism in the Middle East. Debate over whether the Crusades can truly be perceived as an early example of European colonialism continues in medieval historiography, though the evidence for this is thin. The territory taken by the Franks from the Turks had previously belonged to Eastern Christians and had only recently been seized by the Turks themselves.The Crusader States were relatively small and weak, and while they tried to be a bulwark of Christianity in the Holy Land, the Crusader States were reconquered centuries before modern European colonialism began. Nonetheless, the Crusades and the Crusader States galvanized the Christians of Western Europe to expand their world. While it remains unclear how much that world expanded in practical terms such as trade, or how it affected later attitudes during the expansion to the New World and other regions, it definitely engaged the European mind in both positive and negative ways. As such, the crusades soon achieved near-mythic status in the European literature and remain among the most important events of the Middle Ages.In the 50 years following the First Crusade, the Latin states in the East were consolidated, but there were also growing tensions and new challenges. Against this backdrop, the fall of the County of Edessa in December 1144 at the hands of Zengi, the atabeg of Aleppo and Mosul, was a catastrophic event. Founded in 1098 by the future King Baldwin of Boulogne, Edessa was the first Crusader state, as well as the northernmost, weakest, and least populated. It was constantly exposed to Muslim attacks, and news of its fall reached Europe at the beginning of 1145, and the fall was the catalyst for the Second Crusade. Furthermore, the Crusader states were also concerned about their relationship with the Byzantine Empire. Relations with the Empire were often tense. As early as 1105, Bohemond of Antioch travelled to the West in search of troops to fight the Muslims while concealing his intention to attack parts of the Byzantine Empire. He reportedly obtained papal acquiescence, though not an explicit bull.The last major failure of the Crusades came in 1221 after a disastrous advance towards Cairo, and though it was blamed on divided leadership and logistics, it had massive ramifications for the region, the collapsing Crusader States, and the floundering Byzantine Empire moving forward.
