Crusades refer to periodic military events that took place between 1096 and 1272. These expeditions were organized by European Catholic Christians, in line with the wishes of the Pope, in order to gain control over the Muslim-dominated Middle Eastern lands. Its main aim is to capture the Middle Eastern regions, especially Jerusalem, which are considered the Holy Land, and to bring these lands, which are considered holy for Christianity, under Christian domination.
The Crusade, which was the first of the Crusader armies affiliated with the Catholic Church, started in 1096 and ended in 1099. These expeditions were carried out eight times in total to the Middle East and Anatolia until 1492. The Crusades, “Crusader Raidsi” or “ReconquestIt is also referred to as “.

Battle of ManzikertHis aim was to expel the Turks, who had become stronger in Anatolia and the Middle East after 1960, from the lands considered sacred by Christians.

The Birth of the Crusade Idea
The inspiration for the Crusades is actually the Reconquista movement, which was initiated for the reconquest of Muslims in Spain and Portugal. Muslims had established dominance in Spain and Sicily. The Christian kingdoms in the Iberian Peninsula defended the cities held by Muslims, whom they saw as a common enemy, and especially the cities that were considered sacred. Jerusalem‘They started a movement to take back the city, which lasted from the 9th century to the end of the 15th century.
In fact, in 1086 Pope Gregory VII. Gregorius to the East crusade He had the idea of organizing. However, this idea was discontinued by his successor, II. Applied to Urbanus. After the Battle of Manzikert in 1071, Anatolia was exposed to Turkish raids and Seljuk Turks established a strong dominance. The Turks, who captured Syria and Palestine with these successful conquests, made the Christian world uneasy.
Byzantine Emperor Alexios I, known for his political success, requested help from the Pope to deal with the Turks. The Pope accepted this request, but his main goal was to capture the Eastern lands, especially Jerusalem, rather than helping Byzantium. It was thought to provide control over the Eastern Christians, who were considered “Hereks” who did not embrace the views of the Papacy, and to save Europe from the crisis it was in. Because in 1094, due to problems such as severe drought, hunger, misery, epidemics and increasing population, the East became almost a heavenly place in the eyes of the West.

The primary goal for the counts, dukes and knights who would participate in the Crusades was financial gain and possession of new lands. Because French, Normans, Lombards An organized army consisting of various nationalities was formed and came to Constantinople in 1097. Alexios I felt great concern when he saw these huge armed forces. He did not allow them passage through his territory and declared that he would not allow them to go to Islamic countries unless they adhered to their commitment to give him Antioch. In fact, its purpose was to encourage the Crusaders to go to Islamic countries and to ensure that they regain the lands they lost from the Turks.
