Peter the Hermit led 20,000+ untrained peasants. Massacred Jews in Rhineland. Annihilated by Seljuks at Civetot. Few reached Constantinople.

8-month siege. Starvation, disease, desertion. Bohemond bribed a tower guard. City fell. Then Kerbogha's relief army besieged the besiegers. Peter Bartholomew "discovered" the Holy Lance—morale surged. Crusaders sallied, routed Kerbogha.
Coastal route via Tripoli, Beirut, Tyre, Acre, Caesarea. Siege of Jerusalem (June–July 1099): Godfrey of Bouillon's siege towers breached walls. Massacre of Muslim/Jewish defenders and civilians. Godfrey became Advocatus Sancti Sepulchri (Defender of the Holy Sepulchre), refusing "king."
Four Crusader states established. Two centuries of conflict followed. The journey's suffering and violence shaped medieval Christendom's self-image—and the Muslim world's memory of invasion.
