Harold of Gloucester was a young boy who died in 1168 in Gloucester, England. Following his death, Benedictine monks falsely alleged that he had been ritually murdered by the local Jewish community. This accusation served as an early example of the blood libel myth, which falsely claimed that Jews engaged in ritualized child murder. Although a brief period of veneration occurred in Gloucester, the movement to establish him as a saint did not gain lasting official support and eventually faded away.
