1147 May 8, RAMERUPT (Rameru, France)
Encouraged by Peter the Hermit, a mob attacked the Jews on the second day of Shavuot (Pentecost). Rabbenu Tam was one of the mob's victims. After being stabbed five times (to match the five wounds of Jesus) he was saved by a passing knight. His house was ransacked, however, and a Torah scroll destroyed.
