In 1095 Byzantine emperor Alexius I Comnenus sent envoys to the west requesting military assistance against the Seljuk Turks. The message was received by Pope Urban II at the Council of Piacenza. Later that year, in November, Urban called the Council of Clermont to discuss the matter further. In convoking the council, Urban urged the bishops and abbots whom he addressed directly, to bring with them the prominent lords in their provinces.
