The moment in context
The crusade drew its first blood in Europe, against Europeans, and the reason lay in the logic of the summons itself. Preachers had told ordinary men that they were marching to fight the enemies of Christ, and some asked why they should travel so far to do so while Jews lived in their own towns. In the spring of 1096 bands moving through the Rhineland attacked the Jewish communities of Speyer, Worms and Mainz, killing thousands who would not accept baptism, sometimes as local bishops tried and failed to shelter them. Explaining how a licence for distant holy war was turned against vulnerable neighbours does not excuse it, and these communities are remembered here as victims rather than as a prelude to adventure. The undisciplined People’s Crusade that ran ahead of the lords was then annihilated by the Turks near Nicaea.
