The Peasants' Crusade: Peter the Hermit, a native of Amiens in France, led 40,000 commoners out of Cologne on the Peasants' Crusade in April, and today they are shipped across the Bosphorus by Emperor Alexius I Comnenus of Constantinople.
Peter only arrived in Constantinople at the end of July with 30,000 people, and Alexius I had welcomed them at first. However, these peasant Crusaders were so decimated by hunger and disease that they caused a great deal of unrest, looting churches and houses around Constantinople.
Alexios I Komnenos had no desire to provide food and care for 30,000 paupers, none of whom had resources to pay for what they needed. Thus, Alexius has them taken to Anatolia as quickly as possible.
Made up of poorly organized groups led by Peter the Hermit and Walter the Penniless (Gautier sans-Avoir, who had led a separate contingent from Peter, most of whom were killed by the Bulgarians), the Peasants' Crusade would proceed to pillage Asia Minor and meet with a very messy end.
