In the early Middle Ages, and with the rise of European Christendom, sporadic anti-Jewish practices occurred as Jewish legal rights dwindled. These included, in diverse times and places, the right to own land or to receive education for emerging professions. Violence reached a crescendo during the era of the Crusades. Accusations of host desecration, the blood libel, the poisoning of wells, and the banishment from this or that realm happened periodically, though not throughout the continent simultaneously.
