The First Crusade (1095-1102) was a military campaign by western European forces to recapture the city of Jerusalem and the Holy Land from Muslim control. Conceived by Pope Urban II following an appeal from the Byzantine emperor Alexios I Komnenos, the Crusade was a success with Christian forces taking control of Jerusalem on 15 July 1099.
