In 1095, at the Council of Clermont, Pope Urban II calls for a Crusade to the Holy Land.
The Council of Clermont was a mixed synod of ecclesiastics and laymen of the Catholic Church, called by Pope Urban II and held from 18 to 28 November 1095 at Clermont, Auvergne, at the time part of the Duchy of Aquitaine.
Pope Urban’s speech on November 27 included the call to arms that would result in the First Crusade, and eventually the capture of Jerusalem and the establishment of the Kingdom of Jerusalem. In this, Urban reacted to the request by Byzantine emperor Alexius I Comnenus who had sent envoys to the Council of Piacenza requesting military assistance against the Seljuk Turks
Several accounts of the speech survive, the one by Fulcher of Chartres, who was present at the council, is generally accepted as the most reliable.
