A similar movement arose again in 1399, again in Northern Italy in the form of the White Penitents or "Bianchi" movement. This rising is said to have been started by a peasant who saw a vision. The movement became known as the "laudesi" from their constant hymn singing. At its peak, a group of over 15,000 adherents gathered in Modena and marched to Rome, but the movement rapidly faded when one of its leaders was burned at the stake by order of Boniface IX.
