When Judea fell under the authority of the Seleucid Empire, the process of Hellenization was enforced by law. This effectively meant requiring pagan religious practice. In 167 BCE Jewish sacrifice was forbidden, sabbaths and feasts were banned and circumcision was outlawed. Altars to Greek gods were set up and animals prohibited to Jews were sacrificed on them. The Olympian Zeus was placed on the altar of the Temple. Possession of Jewish scriptures was made a capital offense.
