What was the pope urbans second main reason for calling for the first crusade or war of the cross?

Answer 1

Pope Urban II's second main reason for calling for the First Crusade was to aid the Byzantine Empire, which was under threat from Muslim forces, particularly after the fall of the city of Jerusalem. He sought to unite Christians in Europe to reclaim the Holy Land and protect fellow Christians, emphasizing the spiritual benefits of participating in the crusade, including the promise of forgiveness of sins. This call also aimed to redirect the aggressive tendencies of European knights towards a common religious goal, thereby reducing internal conflicts.
