On this day in 1924, the largest gathering of the Ku Klux Klan ever held in New England took place at the Agricultural Fairgrounds in Worcester. Klansmen in sheets and hoods, new Knights awaiting a mass induction ceremony, and supporters swelled the crowd to 15,000. The KKK had hired more than 400 "husky guards," but when the rally ended around midnight, a riot broke out. Klansmen's cars were stoned, burned, and windows smashed. KKK members were pulled from their cars and beaten. Klansmen called for police protection, but the situation raged out of control for most of the night. The violence after the "Klanvocation" had the desired effect. Membership fell off, and no further public Klan meetings were held in Worcester.
