The First Crusade was a military expedition from 1096 to 1099 by Western Christianity to regain the Holy Lands taken in the Muslim conquest of the Levant, ultimately resulting in the recapture of Jerusalem. It was launched in 1095 by Alexios I Komnenos, who requested that western volunteers come to his aid and help to repel the invading Seljuq Turks from Anatolia. 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 Islamic rule.
