The official start date was set as August 15, 1096. Those armies that left before that time are considered part of the People's Crusade. 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.
Because the First Crusade was largely concerned with Jerusalem, a city which had not been under Christian dominion for 461 years, and the crusader army had refused to return the land to the control of the Byzantine Empire, the status of the First Crusade as defensive or as aggressive in nature remains controversial.homas Asbridge argues that the First Crusade was Pope Urban II's attempt to expand the power of the church, and reunite the churches of Rome and Constantinople, which had been in schism since 1054.
