In 1840, the Jews of Damascus were falsely accused of having murdered a Christian monk and his Muslim servant and of having used their blood to bake Passover bread. A Jewish barber was tortured until he "confessed"; two other Jews who were arrested died under torture, while a third converted to Islam to save his life. Throughout the 1860s, the Jews of Libya were subjected to what Gilbert calls punitive taxation. In 1864, around 500 Jews were killed in Marrakech and Fez in Morocco. In 1869, 18 Jews were killed in Tunis, and an Arab mob on Jerba Island looted and burned Jewish homes, stores, and synagogues. In 1875, 20 Jews were killed by a mob in Demnat, Morocco; elsewhere in Morocco, Jews were attacked and killed in the streets in broad daylight. In 1897, synagogues were ransacked and Jews were murdered in Tripolitania.
