Pope Urban the II wanted to get back the Holy Land in which had been over taken by the Muslims at the time. Having the Holy Land was some what of a pride thing since Islams, Muslims, and Christians all use it for their Holy Land.
First crusade was initiated by Pope urban II. He believed in forgiveness, he told to the fighters who fought for their holy lands that their sin will forgive by the grace of the god. He thought crusades would increase and develop religious feelings in the fellow disciple's mind and will end fighting between Christian lords.
He also thought that the holy land would be reclaimed Seljuk Turks. Power of Pope, wealth of Church get increase after the crusades.
