Three of these armies never made it past Hungary; two others (under Peter the Hermit and Walter Sansavoir) were defeated by Kilij Arslan of Nicaea. Traditionally, the First Crusade deals with those who left after that official start date. As with the People's Crusade, these crusaders did not form one unified army.

These incursions prompted the emperor of Byzantium, Alexius I Comnenus to send a delegation to Piacenza, Italy, asking Pope Urban II in March 1095 for help against the Turks.
