Historical analysis of the event
Background
As the Clermont appeal spread through France and Germany, some preachers and armed groups embraced the idea that war on “the enemies of Christendom” need not be limited to distant Muslims. The search for money to finance the expedition also made Jewish communities a target. The episcopal cities of the Rhine were home to long-established communities living under the bishops' protection.
Course of events
The first attack came at Speyer on 3 May 1096; Bishop John protected most of the community and the number killed remained limited. At Worms, in attacks on 18 and 25 May, most of the community was killed, including those who had taken refuge in the bishop's palace. Count Emicho of Leiningen's army entered Mainz on 27 May; Archbishop Ruthard's protection collapsed and most of the community was killed or took their own lives rather than submit.
In June the Jews of Cologne were dispersed to hide in surrounding villages, but attacks took place in some of these places too. Forced baptisms and killings were also recorded at Trier, Metz, Regensburg and Prague. Emicho's army was later scattered before Moson (Wieselburg) in Hungary and never reached the East.
Outcome and significance
The attacks were remembered as a deep rupture in European Jewish history, and the memory of the victims entered Hebrew liturgy. Some of those forcibly baptised returned to their faith in 1097 with the permission of Emperor Henry IV. The events show the gap between the official aims of the crusade appeal and how it was interpreted on the ground, and the limits of the bishops' power to protect.
Sources and debates
The main sources are three Hebrew texts: the chronicle attributed to Solomon bar Samson, the account of Eliezer bar Nathan, and the one known as the Mainz Anonymous. On the Latin side, Albert of Aachen reports the attacks critically. The figures and the narratives of kiddush ha-shem (martyrdom for the faith) in the Hebrew chronicles bear traces both of the violence itself and of later communal memory, and must be read with care.
