The Worms massacre was the murder of at least 800 to 1,000 Jews from Worms, Holy Roman Empire (now Germany), during the events of the First Crusade (More precisely by the People's Crusade) under Count Emicho in May, 18-25 1096. This massacre is a part of series of mass murders of Jews that happen in the Rhineland Jewish communities that known as The Rhineland massacres or Gzerot Tatnó.
The massacre at Worms was one of a number of attacks against Jewish communities perpetrated during the First Crusade (1096–1099). Followers of Count Emicho arrived at Worms on 18 May 1096. Soon after his arrival, a rumor spread that the Jews had boiled a Christian alive, and used his corpse to contaminate water to poison the town's wells.
