 copied this breif descrtion from  wikipedia Crusades
The Crusades were a series of religious expeditionary wars blessed by Pope Urban II and the Catholic Church, with the stated goal of restoring Christian access to the holy places in and near Jerusalem. Jerusalem was and is a sacred city and symbol of all three major Abrahamic faiths (Judaism, Christianity and Islam).^[1] The background to the Crusades was set when the Seljuk Turks decisively defeated the Byzantine army in 1071 and cut off Christian access to Jerusalem. The Byzantine emperor, Alexis I feared that all Asia Minor would be overrun. He called on western Christian leaders and the papacy to come to the aid of Constantinople by undertaking a pilgrimage or a crusade that would free Jerusalem from Muslim rule.^[2] Another cause was the destruction of many Christian sacred sites and the persecution of Christians under the Fatimid caliph Al-Hakim.


The crusaders comprised military units of Roman Catholics from all over western Europe, and were not under unified command. The main series of Crusades, primarily against Muslims in the Levant, occurred between 1095 and 1291. Historians have given many of the earlier crusades numbers. After some early successes, the later crusades failed and the crusaders were defeated and forced to return home. Several hundred thousand soldiers became Crusaders by taking vows;^[3] the Pope granted them plenary indulgence. Their emblem was the cross — the term "crusade" is derived from the French term for taking up the cross. Many were from France and called themselves "Franks," which became the common term used by Muslims.^[4]


The term "crusade" is also used to describe religiously motivated campaigns conducted between 1100 and 1600 in territories outside the Levant^[a] usually against pagans, heretics, and peoples under the ban of excommunication for a mixture of religious, economic, and political reasons.^[b] Rivalries among both Christian and Muslim powers led also to alliances between religious factions against their opponents, such as the Christian alliance with the Islamic Sultanate of Rûm during the Fifth Crusade.
